Even a 1 month project with one good senior engineer working on it will get 20+ different files and 5,000+ loc.

Real programming is on a totally different scale than what you're describing.

I think that's true for most jobs. Superficially an AI looks like it can do good.

But LLMs:

1. Hallucinate all the time. If they were human we'd call them compulsive liars

2. They are consistenly inconsistent, so are useless for automation

3. Are only good at anything they can copy from their data set. They can't create, only regurgitate other people's work

4. AI influencing hasn't happened yet, but will very soon start making AI LLMs useless, much like SEO has ruined search. You can bet there are a load of people already seeding the internet with a load of advertising and misinformation aimed solely at AIs and AI reinforcement
