  >  It took two initial prompts and a few tiny follow-ups. GPT-5.2 running in Codex CLI ran uninterrupted for several hours, burned through 1,464,295 input tokens, 97,122,176 cached input tokens and 625,563 output tokens and ended up producing 9,000 lines of fully tested JavaScript across 43 commits.

Using a random LLM cost calculator, this amounts to $28.31... pretty reasonable for functional output.

I am now confident that within 5-10 years (most/all?) junior & mid and many senior dev positions are going to drop out enormously.

This is for porting an existing project. It’s an ideal case for LLMs. The results are still pretty different for building up a library from scratch.

However this changes the economics for languages with smaller ecosystems!

yes because this is what we do all day every day (port existing libraries from one language to another)....

like do y'all hear yourselves or what?

I’m afraid the boosters hear nothing.

The commenter you’re replying to, in their heart of hearts, truly believes in 5 years that an LLM will be writing the majority of the code for a project like say Postgres or Linux.

Worth bearing in mind the boosters said this 5 years ago, and will say this in 5 years time.

People say this kind of thing a lot, but in reality the concept of "software engineer" will change and there will still be experience levels with different expectations
