I never ever had to interact on SO and similar sites, I use them solely for searching for solutions, and for that they’re perfect - and probably provide a significant amount of data for answering questions on ChatGPT etc.

It’s not like the internet didn’t work as an answering machine before AI. Often you can enter the exact same prompt into a search engine instead and get better answers. But oh no, you have to click on a website and maybe even scroll down a little!
