It's no wonder Out happened when you really think about it. Nastya doesn't like organic life because it's complicated, it can break, sometimes it's even unfixable.

quote from gender rebels

Nastya is in love with Aurora, and in saying that she is saying "you are not organic life, I can deal with you because you are metal and algorithm and predictable" - we can see this in bedtime story when she says she'll tweak Aurora's story creation algorithm

screenshot from A Bedtime Story

Aurora is not inorganic. She is not ai. She is a space moon made of flesh and blood and teeth and bone. She is not an ai. She is a body that was taken and stripped of autonomy, of the right to self identify, of the right to think- to be imperfect and organic.

The metal is a veneer that hides how messy and traumatized and unfixable she is. From the outside she is a starship. From the inside she can still bleed.

And this makes them fundamentally incompatible. But yet, they are in love.

And really, it's no wonder Nastya fell in love with Aurora. Let's take a look at Nastya's home planet, or at least home society:

"Terminals were scattered across the planet. There was one on every street corner, one beneath every lamppost and one in every commune block." "The midwife-machine performs a series of programmed manœuvres to quieten [the baby]. It cradles it and hums at several pitches until it finds one that seems most soothing. Mechanical arms stroke the baby’s flesh even as others start the process of implanting augmented reality interfaces into its nervous system." "The Czar an atrophied frame, never present in the real world and worn to dust by the chemical compounds that kept his brain alive so it could live forever in a perfect virtual paradise. The Rabotnik a copy, a mind preserved unchanging in the instant before its death and placed in an everlasting metal frame." (Cyberian Demons)

Its safe to say the world Nastya was born into, from the very minute she was born, was ridden with technology. She has augmented reality interfaces inplanted into her from birth. It would stand to reason that being taken from this society, wherein technology is everywhere, inside and out, would stand for a bit of a shock.

Aurora too had been augmented by the Cyberia.

While it is stated that the last time Nastya had used the ports themselves was directly before her death — "The last time she had used the ports, her tutor had ripped them out of her as the rebels stormed the palace" — Aurora is laced with Cyberian technology. I'd imagine she has something of a 'bluetooth wireless connection' with Aurora, rather than the physical data transfer of files between the ports and Nastya, it may as well be similar enough.

Imagine being Nastya, going from Cyberia, wherein there is augmented reality contantly, transplanted onto a ship with metal blood, a jonny, and a vampire. To Aurora, where the only bits of augmented reality run through Aurora.

Of course she'd fall in love with her. Aurora is familiarity. Aurora isn't organic. Aurora isn't human.

And of course when the undeniable part of aurora that is organic, that is a flesh moon plated in metal with her brain hooked to machines, when so much has broken and been replaced, when, presumably, aurora is less of an algorithm, nastya leaves with the brand cyberia left on her.

Because Aurora healing, becoming more of herself and less of a starship, is messy, and organic, and human.

and hard for nastya.

‘Think how long she’s been flying you around. Think how many bullet holes you’ve punched through her and how many atmospheres you’ve dropped her through. Think how many alterations and improvements we’ve made, Tim to her guns and Ashes to her storage and Brian to her engines and the Toy Soldier to who knows what. How much do you think is left of her after all she’s brought you through?’ Nastya held up the ancient, battered piece of hull plating. Just visible under the grime and scars of particles of space junk was a fragment of the Aurora’s original logo and serial number. Jonny honestly couldn’t remember the last time he had seen a version that hadn’t been painted by the Mechanisms themselves. ‘So she’s free, now.’ Nastya gestured around at the spaceship they were standing in. ‘This Aurora can take you where you want to go. I’m going to take my Aurora somewhere else.’

Aurora was ship of theseus'd. Aurora was improved. Aurora was no longer cyberian. (both literally, and metaphorically)

So nastya left.

Hedy Lamarr was born Hedwig Eva Kiesler in Vienna, Austria on November 9th, 1914 #botd Actor, legendary beauty, and inventor who pioneered the technology that would one day form the basis for today’s WiFi, GPS, and Bluetooth communication systems.

[girlactionfigure]

Hedy Lamarr was considered one of the most beautiful women in Europe. Born Hedwig Eva Maria Kiesler in 1914 to a Jewish family in Vienna, Austria-Hungary, she became a film star in Europe by the 1930s, and soon after, she achieved similar recognition in the U.S. In addition to her acting career, Hedy pursued inventing.   Motivated to assist U.S. efforts during WWII, she focused on designing a radio guidance system for Allied torpedoes that would counter the threat of jamming.   Although her innovation was not used during the war, the principles she developed are now integrated into modern technologies such as Wi-Fi, CDMA, and Bluetooth.   On August 11, 1942, Hedy Lamarr was granted a patent for her revolutionary “frequency hopping communication system,” which forms the basis of much of today’s wireless technology. In recognition of her achievements, she was inducted into the National Inventors Hall of Fame in 2014.

The women who laid the foundation of tech

EDIT: I noticed that this post ended up being reblogged by terfs. If you're transphobic this post is not for you to reblog. I want to celebrate everyone who is not a cis man in this industry, including trans women and nonbinary people in tech, and it was my mistake to only include cis women in this post when there are so many trans women and nonbinary people who have done great things in tech as well. Trans women are women and just as important.

Here you can read about trans ppl in tech, and please do:

https://www.thecodingspace.com/blog/2022-03-01-six-trans-programmers-who-shattered-the-lavender-ceiling/

https://abcnews.go.com/Business/transgender-tech-visibility-obstacles-remain/story?id=76374628

The morning of women's day i attended a super inspiring seminar about being a woman in tech at a large tech company in my city, and now I'm inspired to share what I learned with all of you!

I didn't have time to finish this post on women's day, but it's not too late to post now: every day is a day to celebrate women!

Women actually laid the foundation for a lot of the tech industry.

For example, the first computer, ENIAC, was programmed completely by women! While men were the behind the scenes engineers, it was women who did all the actual programming of ENIAC.

The women who made up the team responsible for programming it were called Jean Bartik, Kay McNulty, Betty Holberton, Marlyn Wescoff, Frances V. Spence and Ruth Teitelbaum.

I think one woman who is finally getting her overdue recognition is Ada Lovelace. She was a mathematician (also often referred to as the first programmer) who created the first algorithm in 1842, which wasn't recognized until 1953! However, since none of her machines were ever completed it was never tested in practice during her time.

She has since been celebrated by giants such as google, and she has given name to a programming language (Ada). She was also the first person to write about what is today known as AI. Back when she was practicing, computers were simply thought of as calculators. But she had an idea that if computers can understand numbers, then that can be translated to letters, and in turn that can lead to computers being able to handle words, and eventually even write, draw and create music.

Hedy Lamarr was a famous Hollywood actress in the 40's, but she was also an inventor who laid ground for what we use today for Wi-Fi, Bluetooth and GPS services.

During WW2 she wanted to contribute positviely to the military efforts against the Nazis, and she tried to figure out how to radio control torpedoes. In 1942 she patented her technology "Secret Communications System", also known as frequency hopping, which laid the foundation for the technology we use today for Wi-Fi, GPS and Bluetooth. It wasn't until 1962 that it was first used for its intended purpose, during the cuban missile crisis.

Grace Hopper invented the first compiler, called A-0, in 1955, and was also part of the Univac team, which was the company also responsible for building ENIAC. She also initiated work on the COBOL programming language.

She was also the one to coin the term "bug" in 1947. Computers back then had lights to visualize their working process (which was also a womans idea to implement btw) and bugs would be attracted to the lights, but usually that was no issue - until a bug made its way into a tube which caused the computer to stop working. Hopper taped the bug to a piece of paper and logged what caused the crash - a bug.

Dorothy Vaughan (left), alongside colleagues such as Katherine Johnson (middle) and Mary Jackson (right), was a mathematician at NASA (called NACA when she started) who worked on the orbit for the first ever manned spaceflight and later also on Apollo 11 that would take humanity to the moon!

When Vaughan started at what was then called NACA, segregation was still prevalent in the US and she was not allowed in the same areas in the office as her white colleagues. Another department was formed for the black staff, and when the director of said department unexpectedly died, she was appointed as the new director and thus became the first ever black woman at that position at NACA/NASA. In 1958 when NACA becomes NASA segregation is forbidden, and that is when Vaughan and her colleagues Johnson and Jackson started working on programming the orbit and later also Apollo 11.

Continuing on the same track of NASA and space, Margaret Hamilton was the Apollo project's first actual programmer. Hamilton became the director of software engineering at NASA in 1965, and she was also the person to first coin the term !

In the image above, she stands next to all the handwritten code that was used to send humanity to the moon. During the early stages of the project when she would speak of "sofware engineering", software development was not taken as seriously as other forms of engineering, and it wasn't regarded as a science, either. She wanted to legitimize software development as an engineering discipline, and overtime the term "software engineering" gained the same respect as any other technical discipline.

And lastly, if you're a woman in STEM, I want to highlight and celebrate you! Being a woman in a male dominated industry is not easy, we often suffer from sterotype threat and are not seen as our own individuals, but rather "the woman" in a room full of men. But just as these women, I'm sure you will achieve greatness!!

We know the Alliance definitely are communicating with each other, and communicating across factions, without audible speech. TVmen are the only ones that regularly use spoken words, and even they’ve seemed to communicate silently. Titan Cameraman can speak, but almost never does. So it seems likely that the primary forms of Alliance communication would be through inaudible transmission of information. And this means opportunities for headcanons!

The Skibidi Toilet fandom tends to headcanon that there’s a sign language as well, and I think that makes a lot of sense. First, we know that cameramen interacted with humans at some point. This must have involved communication, but if they don’t regularly use spoken communication, a simple sign language would make sense because it would be a pain in the arse to have to get a chat app out because your robot wants to bluetooth you a few words like “do you need anything?”. Second, a thought transmission system is likely to feel quite intimate. Humans don’t even feel like using the phone sometimes, so to be literally speaking directly into people’s brains would be a whole other thing. Even if it’s socially normal, like phone calls and small talk (apparently), there’s going to be times when people don’t want to or can’t do that. And third, loads of human cultures have sign languages, so why wouldn’t a robot culture? Sign and transmission languages might be used simultaneously in many circumstances, so there might not need to be signs for everything.

What this means is that the primary Alliance languages are likely to be quite minimal - this is a real thing in many human languages. Names and personal pronouns could be situational or optional. For example, names that aren’t just a descriptor or unit number could be used as status signifiers, indicating that the name bearer is so important that there needs to be a shorthand way of referring to them in conversation. Or maybe the opposite, because there’s only one Titan Cameraman, but there’s loads of soldier cameramen and “that guy with chipped paint that kind of looks like a hamster on his head” is a bit long. Humans love to name stuff, so naming could also be a silly human trick and a way to connect to a special human friend. In the fandom, people often refer to characters’ first and upgraded incarnations differently. Something like this in headcanon could look like their names/signifiers/shorthand signs changing. And a step further, previous names might be considered bad manners or even similar to deadnames if someone’s attached a lot of emotional weight to an upgrade.

Something else interesting that human languages do is avoidance registers when, in certain social situations, people change their language to avoid taboo words. The really interesting ones to me are when people avoid words or word categories for good luck - some cultures have languages used when harvesting so the produce doesn’t go bad, and people in high-pressure jobs sometimes have a taboo on saying things like “it’s a quiet night”. In an Alliance context, this could translate into something like scientists/engineers/etc. not using certain words while working, or even a whole engineering register.

Personal pronouns might not be a big thing, if there’s a way to communicate “the sense of a person” or names are quick enough to sign, a third-person and even first-person pronoun might not be needed unless someone’s emphasising pronoun-ness. The default might be a neutral pronoun-less-ness, which might translate into “they” and “it” in English - or into the common human habit of using “he” for anyone that’s not visibly femme-presenting and not a boat. Some human languages also do fun stuff with pronouns depending on gender and status, so Alliance personal pronouns might be based on something like unit type or status rather than or as well as gender. As the femme-presenting Alliance members seem to have high-status roles, she/her pronouns might have a status association - maybe leading to things like people switching to she/her pronouns to make a point of something being extra official serious business.

Okay, so how does the bat communication system work

They could use signal but tbh. That might be to much functionality on what we would need.

Authentication is like in this case pretty trivial, because they are like 2 dozent people who can all be in the same room at some time and get their devices in person. Maybe they have some kind of rsa token for that. And also they build their own devices (again like 2 dozent or something so)

Also the serverlessness of signal is great, if you dont want your data in some server, but also again. They probably have their own servers anyway. And soemtimes the bat communication network is written like if someone is offline they just never get the message so very normal client2client would work.... I would prefer using the batservers instead however.

Anyway so the signal protocol implements perfect forward secrecy (so if the key got into attackers hands the earlier send messages are save) and perfect backwards secrecy (future messages are safe). So you would keep these parts...

Because again they are only like max 2 dozent people the major drawback of signal (it not scaling well for big group communications) this also does not apply.

Okay now to the part of the wireless communication.... We do have the problem here that most of batman canon is before 2018. After thinking a lot about that and crying a bit i decided, to make any of this work we have to make an au in which Wayne enterprises build a 5G network in gotham in the 90s. In this au 5G would be the first one someone invented, so downgrade attacks would not work.

I also asked my friend for suggestions and he said maybe Wayne Enterprises did build a totally second Network additionall to the normal Gotham wireless network with own bts for the bats. And so the bats can just use their own build protocoll (using Dragonfly and ECDH). The Batman Protocoll would use own headers so the normal bts will just ignore that, and we will encrypt the header, so the headers can not be tracked.

I know some 90s comics also said Oracle is talking to the bats per phone, but for the sake of my sanity we are ignoring that.

Anyway so what do the bats for sure not use:

Fax: many things which irl would need to be somewhat private are send over fax, because this is client2client and not saved on any servers which belong to some external company. However!!! It is also not encrypted and just sends the message on clear text. Everyone with access to the connection could just read that

Wifi (i mean. the batcave might be bigger than 50 meter radius so, maybe they can actually use it there.)

Bluetooth

SMS

like normal phone calls

Hi. I saw ur iterators and they look cool i wanna know the lore(tm)

OOO YES YES! Imma ramble about off the string au too, so putting the explanation of the au before oc lore, if you want to hear just about the oc, feel free to skip the off the string hcs! (note: a lot of my oc lore is rather long, and hard to type out in one go, i will most likely be typing up about an oc with shorter lore)

So first; how does off-the-string work in my au/hcs:

The consciousness and subconsciousness are evenly spread out throughout all of the iterator's systems and mechanisms! Usually the puppet is just used for communication, and to express the iterator's personality. Without the puppet it would be rather difficult to communicate. Now you see: the puppet can be detached from it's mechanical arm, this is most often done in maintenance or during really fancy ceremonies. To go off the string, you need to put your whole consciousness into your puppet, and then detach it from the mechanical arm. The structure would still be up and performing vital functions, however would be in a "sleep" state. You can still vaguely feel your structure if you are off the string.

Although this sounds easy, it really isn't. Since the iterator as a whole is HUGE, they'd need some time to adapt to the limitations of the puppet. They are now on the same level as an ancient, or the animals that walk beneath their structure, which can be rather difficult to adjust to if you're used to being a mechanical god. (think of it like putting all your consciousness into the tip of your finger, you're so so much smaller and vulnerable now) Note: the iterator is also now hyper-aware of their puppet since all of their consciousness, and thus attention, is in their puppet (instead of being spread out like in the structure). (Also another small note I am unsure of where to put: in my hcs, the iterators sort of have a connection to their neurons similar to bluetooth, which means that if the structure is still standing, they do not need to take their neurons along while going off the string, as they'd already have that long distance connection to the neurons) If a disconnection is done right, it is 100% reversible! Just attach the puppet back to it's mechanical arm, and everything would be just like before the iterator detached it's puppet. However if an iterator disconnected improperly, it will be rather difficult to spread their consciousness back through their structure. Also if you die off the string, your consciousness will simply go back to your structure, and you'd need to make yourself a new puppet.

As for why an iterator would need to go off the string:

Many many reasons, some iterators are just curious, others want to see if they can ascend (any void related death will cause ascension for ancients and biological organisms. Several iterators have tried to test if they'd ascend by losing their puppet to the void sea.), and some have been falsely advertised to. Not too long after Sliver's ascension, there was an event labeled the "Disconnection Obsession", where iterators would go off the string to test the aforementioned theory. However there was also a rise of false advertising, with off the string being painted as a vacation or a new solution, and of course you'd want a vacation after some real boring work. Unfortunately off the string is far from a vacation...

Onto OC lore:

I'll be talking about CV! As it's lore is currently one of the only things thats on my mind, and that I can coherently tell through one ramble. Following the disconnection obsession event, CV had gone off the string to test out if the theory of losing your puppet to the void sea will ascend an iterator (probably not be at least CV is being hopeful). Or well, it more so thought it needed to test out this theory. Unfortunately CV was brainwashed by it's council to have the extremist ascensionist views of the world. Deep down it never really had any interest in ascension, it had more interest in archiving religious history to be honest. So CV went off the string with it's neighbors (Visions of Issues Unforeseen, Grim Speculations), and originally it planned to go to the void sea, but overtime it wanted to stay with it's neighbors more (who it became rather good friends with). I nicknamed the trio "The half-group", since originally they were a separate group from DAWNS_ABOUND, before the two groups merged for political allyship back when the ancients were around. Putting this map here as well! The two collapsed iterators near the half-group are early prototypes, who collapsed even before GS (oldest of the half-group, the second model of gen 2 ever made) was built. Early prototypes never really have a long lifespan unfortunately.

Thats about it for now!

LakeTahoe!Series:

Part One: Black Bear Lodge - Your life changes when you meet Manny at Black Bear Lodge.

Part Two: Something Special (NSFW) - Manny gives you a night like no other.

Part Three: Goodbye - You and Manny say goodbye after spending the weekend together.

Postcards: Manny recieves a surprise in the mail.

It’s over a four-hour ride to L.A. Manny’s arranged to stay a couple of days with you before he needs to be in Santo Padre to discuss the pipeline deal with Bishop. It’s become clearer over the past few weeks that Canche has been subsidising his income with club funds. They’re missing a massive portion of cash and that means they can’t buy into the pipeline.

On the drive up he starts to think of it as a blessing in disguise because it allows him to think outside the box, to consider other options. He wants more for Yuma, he wants better, safer options for his brothers, ones that won’t result in prison or a bullet. Santo Padre has been heading that way for a while, they have links to the community, they work with legitimate businesses, their income is clean and constant. Manny wants to emulate that.

He’s exhausted by the time he makes it to your suite; he uses the key you’ve left for him down at reception. It’s a little past ten pm and the day has taken its toll on him. He’s been up since six getting Melina ready for school and dealing with club business, all he wants is to sooth his aching muscles in a red-hot bath.

The lights are dimmed when he steps inside. He removes his boots by the door before padding quietly into the bedroom. They’ve gone all out this time; he thinks as he pauses for a second surveying the view from the window. In the distance he can see the San Gabriel Mountains silhouetted against the night sky.

Everything about this room screams indulgence, the well-made luxury furniture, the dark wood floors, the gourmet snacks in the minibar. It piques his curiosity because he knows you’re getting by on a freelancer’s wage, and he can’t imagine that any magazine would put you up in a place like this, no matter how good your work is.

He finds you in the bathroom, soaking in a tub that large enough to fit another two people inside. You have a glass of whiskey in your hand, classical music serenading you from the Bluetooth speaker in the mirror. You watch as he undresses, his dark eyes fastening on yours as his clothes fall into an untidy pile at his feet. You shift forward and he slips in behind you, the water raising over his weary bones. He exhales at the sensation, sinking low. You lean back against this chest, placing the whisky glass in his hand and he sighs because as relaxed as he is right now, he can’t shake that niggling feeling that this is all to good to be true. He lips brush over your temple, his cheek coming to rest upon your hair as he says.

“I need you to tell me why we’re here tonight because I know that neither of us can afford a suite with a mountain view.”

“It’s comped.” You tell him, tilting your head up so you can meet his gaze.

“Not by your magazine.” He murmurs, his thumb ghosting along the line of your jaw. “These rooms cost nearly two grand a night.”

“No.” You whisper as his lips brush over yours. “A private collector wants to buy my photographs, they’re exhibiting at the Hive Gallery tomorrow, this trip is his way of wooing me.”

“Will you sell?” Manny asks and he feels you smile against his mouth.

“I’m donating them to Arts+Practice, they have a lot of great art programmes for kids in the foster system.” You tell him as he graces your skin with a featherlight kiss. “He thinks he has four days to chance my mind.”

He grins because you, you are just full of surprises.

“I’m sleeping with a hustler.” He murmurs before he kisses you properly.

There’s a softness in it, a tenderness that he reserves only for you. You sigh at the sensation and it’s a noise of contentment, one that he feels in the very depths of his soul because now he knows the truth he can actually relax. He tips his head back and closes his eyes, the water washing over him as the fatigue overtakes him.

“I’m tired tonight.” He tells you, his voice drowsy as your head comes to rest in the crook of his neck.

“Me too.” You mumble. “All that travelling is starting to catch up with me.”

It changes things. If this was supposed to be about sex you would have kicked him out by now or at least made a move, but you haven’t. It means you’re as comfortable with this shift as he is. This thing between you it was always more, this is just your way of acknowledging it. He knows guys who would drive almost three hundred miles for pussy but there’s not many who would do it just to spend the night sleeping next to their lover.  

That’s how the evening ends, you and him curled up in a bed that costs more than your annual salary, his face buried in the curve of your throat as he holds you close.

It’s the best night’s sleep he’s had in a long time.

Love Manny? Don’t miss any of his stories by joining the taglist here.

I don't know if this might be a dumb question, but I'm curious

What are Donnie's headphones connected to exactly?

Oh, that’s a really good question, actually! And a fun one!

Right now the answer is: literally nothing.

Once upon a time, however, the headphone cords attached to his battleshell so they could connect to the battery/computer/processors there. Every piece of tech that Donnie wears, especially in the Nexus, he made himself and he made to fit his exact needs. It’s incredibly important to him, and his headphones have always had special settings and functions to allow him to both block out noise and prevent overstimulation as well as communicate more effectively with Leo mid-battle. The programming can filter out the crowds but recognize his twin brother’s voice, so they can talk to each other in the Nexus. And while Donnie has always obviously been an engineering genius, he also made the original design when he was eleven. Back then, he didn’t quite have the experience or skill needed to make a wireless system of that caliber and level of sensitivity with a connection he could rely on 1000% of the time. There’s no space for Bluetooth errors or radio feedback when you’re fighting in the Nexus. So, he made them wired instead, connecting directly to the battleshell that housed all the actual software/programs/etc to ensure they never unpaired, lagged, or glitched out on him.

Since then, he’s improved enough that setting up a wireless system like this is child’s play. But at that point, the public was used to Donnie’s ‘headphone wires’ and they were considered an iconic part of the outfit, so…

He kept them! (He’s not allowed to get rid of them, actually. They’re a part of the BRAND.) The wires now are completely useless and only there for show, and they tuck into his pockets rather easily, where he had some small hooks sewn where the wires can be “docked” so to speak.

Owners of Spotify's soon-to-be-bricked Car Thing device are begging the company to open source the gadgets to save some the landfill. Spotify hasn't responded to pleas to salvage the hardware, which was originally intended to connect to car dashboards and auxiliary outlets to enable drivers to listen to and navigate Spotify.

Spotify announced this week that it's bricking all purchased Car Things on December 9 and not offering refunds or trade-in options. On a support page, Spotify says:

We're discontinuing Car Thing as part of our ongoing efforts to streamline our product offerings. We understand it may be disappointing, but this decision allows us to focus on developing new features and enhancements that will ultimately provide a better experience to all Spotify users.

Spotify has no further guidance for device owners beyond asking them to reset the device to factory settings and “safely” get rid of the bricked gadget by “following local electronic waste guidelines.”

The company also said that it doesn’t plan to release a follow-up to the Car Thing.

Early Demise

Car Thing came out to limited subscribers in October 2021 before releasing to the general public in February 2022.

In its Q2 2022 earnings report released in July, Spotify revealed that it stopped making Car Things. In a chat with TechCrunch, it cited “several factors, including product demand and supply chain issues.” A Spotify rep also told the publication that the devices would continue to “perform as intended,” but that was apparently a temporary situation.

Halted production was a warning sign that Car Thing was in peril. However, at that time, Spotify also cut the device’s price from $90 to $50, which could have encouraged people to buy a device that would be useless a few years later.

Car Thing's usefulness was always dubious, though. The device has a 4-inch touchscreen and knob for easy navigation, as well as support for Apple CarPlay, Android Auto, and voice control. But it also required users to subscribe to Spotify Premium, which starts at $11 per month. Worse, Car Thing requires a phone using data or Wi-Fi connected via Bluetooth in order to work, making the Thing seem redundant.

In its Q1 2022 report, Spotify said that quitting Car Thing hurt gross margins and that it took a 31 million euro (about $31.4 million at the time) hit on the venture.

Open Source Pleas

Spotify's announcement has sent some Car Thing owners to online forums to share their disappointment with Spotify and beg the company to open source the device instead of dooming it for recycling centers at best. As of this writing, there are more than 50 posts on the Spotify Community forums showing concern about the discontinuation, with many demanding a refund and/or calling for open sourcing. There are similar discussions happening elsewhere online, like on Reddit, where users have used phrases like “entirely unacceptable” to describe the news.

A Spotify Community member going by AaronMickDee, for example, said:

I'd rather not just dispose of the device. I think there is a community that would love the idea of having a device we can customize and use for other uses other than a song playback device. Would Spotify be willing to maybe unlock the system and allow users to write/flash 3rd party firmware to the device?

A Spotify spokesperson declined to answer Ars' questions about why Car Thing isn't being open sourced and concerns around e-waste and wasted money.

Instead, a company rep told Ars, in part: “The goal of our Car Thing exploration in the US was to learn more about how people listen in the car. In July 2022, we announced we’d stop further production and now it’s time to say goodbye to the devices entirely.” I followed up with Spotify's rep to ask again about making the device open source but didn't hear back.

At this point, encouraging customers to waste nearly $100 on a soon-obsolete device hasn't resulted in any groundbreaking innovations or lessons around “how people listen in the car.” In their initial response, Spotify's rep pointed me to a Spotify site that searches Spotify's newsroom for “how to listen to Spotify in the car.” One of the top posts is from 2019 and states that “if your car has an AUX or USB socket, using a cable is probably one of the fastest ways to connect by using your phone.”

As for Spotify, using customer dollars for company-serving learning experiences isn't the best business plan. And for regular users, it's best to avoid investing in an unproven hardware venture from a software company.

As Redditor Wemie1420 put it:

Doesn’t feel great that there is literally no alternative other than trashing it. Feels like we’re being punished for supporting them. Dissuades me from buying anything Spotify puts out in the future. I feel like there would be some way to approach this without being like, ‘yeah we’re done. Just throw it out it’s a waste of money now.’
