Been thinking about a Modern!Babel AU centered around colleges aimed around Silicon Valley
Immigrant kids being funneled into CS because it’s the field where the money is (linguistics? Where’s the money in that? You want to starve?).
International students coming to America because all the Big Programming Languages and their documentation are in English, because translations of documentation is to err and to betray, because English is the programming lingua franca, because if you don’t know English then you’ll be “trailing edge.” Source
“As an American and native English-speaker myself, I have previously been reluctant to suggest this, lest it be taken as a sort of cultural imperialism. But several native speakers of other languages have urged me to point out that English is the working language of the hacker culture and the Internet, and that you will need to know it to function in the hacker community.” Source
So they come to America to improve their English because you have to be fluent to be taken seriously. Or maybe they’re born in America and can feel the rot of their native tongue as they grow up, even as they learn more and more programming languages.
Java, C++, Ruby, XML, Python, Swift, PHP, etc.
It’s funny, but programmers, even as they’ve decided on English as the one true language, they create more and more programming languages to suit their needs/problem solving efficiency:
Source
[ID: XKCD comic that is titled "How Standards Proliferate (See: A/C chargers, character encodings, instant messaging, etc.)" It reads,
Situation: There are 14 competing standards. Cueball (stick figure): 14?! Ridiculous! We need to develop one universal standard that covers everyone's use cases. Ponytail (other stick figure): Yeah! Soon: Situation: There are 15 competing standards.
End ID]
(transcript taken from the ExplainXKCD wiki)
And of course, the students from countries on the Indian subcontinent are acutely aware of the unbalanced nature of the work they do, the way they’re expected to do export IT work, despite the digital divide in India, Bengal, Pakistan, etc. Especially since it’s a sign of being well-educated (wealthy) to speak English fluently thanks to the history of British Imperialism on the subcontinent.
Chinese IT students sink or swim thanks Mandarin monolinguism making it difficult to learn English. Americans programmers struggle not to link choppy English with choppy code, even while being monolingual themselves!
Not to mention the heavy sexism in the IT field! Female programmers taking on nicknames on emails and resumes to pretend to be men, so they’ll be taken seriously. Despite the history of women like Ada Lovelace being foundational to computers.
And of course we gotta bring up the ethics of AI, how it’s a march towards the inevitable that only Luddites would oppose. Despite the millions who’d lose their jobs once implemented into the workplace.
Commercial transportation sector lost to self-driving cars.
Digital artists lost to DALL-E.
Manufacturers automated.
But can’t they tell that progress is inevitable? That this is the future and to try to stop it is foolish?
As Anand Giridharadas put it in Winners Take All:
“In [Silicon] Valley, prediction has become a popular way of fighting for a particular future while claiming merely to be describing what has yet to occur”
Elon Musk is a genius. Bill Gates is so charitable. Bezos is customer obsessed, and they’re the future, don’t you see? Infinite growth forever and ever.
Tower of Babel? Valley of Silicon.
Unfortunately I suck at STEM, and I’m an uncultured Asian American, so I don’t know programming languages well, nor do I know enough about other cultures to do Ramy, Victoire, Robin, or Letty justice. Just the bare bones to see the structure of this AU and put it out in the world to see if anybody would like to play with it or add on.
#babel or the necessity of violence#babel#babel an arcane history#babel rf kuang#my thoughts#infinite growth is the silver#or maybe crypto as silver lol#Silicon Valley is babel#tech progress is our version of the inevitable empire#okay now this is the part in my notes where I ramble#Silicon Valley shined so bright but I feel like we’re reaching the point where it’s bloating everything#not everything can be solved by programming#AHEM NFTs are a nonsense solution made by tech bros to scam money under the illusion of useful technology#bc we want that infinite growth baby#I don’t hate AI but I do think the way it’s being implemented right now is unethical#and that said unethical-ness is being buried under the idea of ‘pragmatism’ or ‘progress’#the way a certain type STEM major considers feelings to be ‘irrational’ and therefore to be ignored#honestly that gives me repressed Robin vibes#I don’t actually think there’s anything wrong with there necessarily being a lingua franca for STEM fields#I get that it’s useful for international communication#but also it’s like a colonialist elephant in the room that could be explored through creative liberties

i’ve come to the conclusion that in many ways, r.f. kuang’s the poppy war is a quintessentially modernist text
#esp when it comes to the contact between the nikarans and the hesperians#thematically it tracks with several key modernist concerns#like folk tradition vs. technological development#emphasis on individual experience#depictions of war and violence#i mean it makes sense since the story is based on 1930s-1940s china#the poppy war#rf kuang
