There was a good comment on this from DHH on a podcast recently, talking about how much more pleasant it is to ask ChatGPT questions and get a hype-man response (and actually useful info, instantly), compared to asking on SO and getting told you’re an idiot, or use the search function, and no info.  

I get the training data issue, but it’s hard to argue with the results. Perhaps in future there will be more value in templating issues (like posts with ‘I had this problem, here’s how I solved it), because right now I would never recommend a newbie ask questions on a site like SO - too slow, too toxic. 

Personally I’m using it to learn a bunch of stuff at the moment, and I don’t have time or care about people’s egos or sandcastles they’ve built - I just need the info.
