For some reason you are just having a bad moment mate, rejoice! Nothing is dead.
I mean Reddit is still alive, like it or not I don't think it's going to change any time soon.
Lemmy does its own things, sure it didn't grow as expected but it is doing good, those things take time and we should not expect Lemmy to become the new Reddit.

For me the main issue on Lemmy is the number of thread/community/people that want to talk absolutely about Reddit, at this point this is just counterproductive it's like people can't get over it, the first few months it was okay but now it's just non sense.
