Still incredibly helpful. Therapy? Helped me a couple of times on some dark days. It’s not a replacement for it, but it helped me. Search engine? Why not? As long as you verify claims, you’re good, and especially nowadays the answers are preferable to whatever Google thinks should be on the first 10 pages (hint: it’s all crap). Cheap coding labour? Again, as long as you verify. A senior programmer can get a lot more done in a day this way.
It’s not necessarily factual or correct, no. But it’s incredibly helpful and useful. As always, the real answer is somewhere in the middle.
Just don’t ask it about politics. It’s so blatantly obviously biased.
