StackOverflow answers are outdated. Every time I end up on that site these days, I find myself reading answers from 12 years ago that are no longer relevant.

I see plenty of old answers that are still very relevant. Suppose it depends on what language/tech tags you follow.

There have been many times I have seen someone complain on the meta site about answers being old and outdated, and then they give specific examples, and I go check them out and they're actually still perfectly valid.
