Re: "as long as it isn't for something important"
Absolute rubbish.
With 40+ years of development across a number of technologies and having worked on, designed and built many business systems, AI can absolutely generate 100% functional code corresponding to my needs. I've been there, done that and used it. No I'm not going to use it to write an entire system but I've used it multiple times to deliver completely working functional libraries/services/factories (amend according to your language of choice) many of which consist of several hundred lines of code, saved me days worth of work, passed unit tests and now live in production systems.
I find people who rubbish AI tend to either have not used it, or not learnt how to use it well, or came to it with unreasonable expectations.
Having lived through a number of technology changes over my years on this earth, I find great similarity with both the advent of the PC and later with the advent of the internet and particularly the dot-com boom. Both of those had many people claiming it was a fad and would implode, others claiming that the world would drastically change (usually with claims that no one would have jobs)... And the truth, as always then and now with AI is somewhere in between.
