SO died some time ago already though; I'd say even before AI.

I remember that I once asked a question about dual-licencing MIT and GPL 2.0 in the same project. Within an hour or two, it was downvoted to -7. Now this alone is already quite concerning (it was a genuine question), but what was even more annoying was that not a single person who downvoted this, explained as to why. So, if my time investment here for asking a question, gets negative karma without any explanation, and then subsequently no useful answer at all: what is the point of SO? I still answered a few questions here or there, but the whole karma system just discourages contributions and I stopped using it with regards to both asking anything or giving answers.

SO is not useless since some answers still hold useful answers, but they really should have started to fix SO early on. Instead they just gave up.
