As a software developer, the one usecase where it has been really useful for me is analyzing long and complex error logs and finding possible causes of the error. Getting it to write code sometimes works okay-ish, but more often than not it's pretty crap. I don't see any use for it in my personal life.

I think its influence is negative overall. Right now it might be useful for programming questions, but that's only the case because it's fed with Human-generated content from sites like Stackoverflow. Now those sites are slowly dying out due to people using ChatGPT and this will have the inverse effect that in the future, AI will have less useful training data which means it'll become less useful for future problems, while having effectively killed those useful sites in the process.

Looking outside of my work bubble, its effect on academia and learning seems pretty devastating. People can now cheat themselves towards a diploma with ease. We might face a significant erosion of knowledge and talent with the next generation of scientists.
