AI coders think they’re 20% faster — but they’re actually 19% slower

And it’s not even including the fixing of vibed bugs and security vulnerabilities. Nice.

this is purely anectodal, but i've tried getting coding help from gen ai a few times and it was never helpful

the last time i tried was particularly ridiculous: i was looking for z-combinator implementations in rust on google and gemini gave me an implementation suggestion. for those who don't know, the z-combinator is an eager variant of the y-combinator and the point of both of those is allowing you to implement recursion without using recursion directly

the code generated by gemini used recursion

and it didn't even compile

Best coding use I've found for it so far are simple, very clearly defined, small apps or modules. As soon as any vagueness enters the picture you'll spend more time analyzing what it produced than is worth it. You might be able to use it as a starting point.

All of our apps eventually get real world stress tested against our giant test databases and load testing.

Every time I have used GenAI to do my coding its been for switch/cases because its FAST. I don't trust it for anything else because I let it do some work for me once, and I got snakebit with a prod issue.

It wasn't just me but a senior too.

Ai-only vibe coders. As a development manager I can tell you that AI-augmented actual developers who know how to write software and what good and bad code looks like are unquestionably faster. GitHub Copilot makes creating a suite of unit tests and documentation for a class take very little time.
