Writing lines of code by hand is all of human software development? Pretty sure in all of those companies its still software engineers writing the code, even if they're using LLMs to do it.

Unless you're making the claim that software engineers aren't involved or that only writing code is software development.

Yes it means in corporations across the globe, the majority of code was no longer being written by humans long before the majority of code was no longer being written by humans.

Also remember, the majority of all human software development has been wiped out 18 months ago but the dwindling will keep going by the quarter until the majority of all human software development has been wiped out.

Nonsense. Nearly every software house in the world has just as many or nearly as many programmers as they did 7 years ago when GPT-2 was "too dangerous to release." You live in a very tiny bubble if you think most businesses are building software without humans. Total horse shit.
