You asked whether it's really better than "what we already had with search engines, online documentation and online Q&A sites".
How have you found it not to be significantly better for those purposes?
The "not good enough for you to trust" is a strange claim. No matter what source of info you use, outside of official documentation, you have to assess its quality and correctness. LLM output is no different.
At this point I am close to deciding to fully boycott it yes
> If you try it yourself you'll soon find out that the answer is a very obvious yes
I have tried plenty over the years, every time a new model releases and the hype cycle fires up again I look in to see if it is any better
I try to use it a couple of weeks, decide it is overrated and stop. Yes it is improving. No it is not good enough for me to trust
