What is there to be optimistic about?

And Fediverse in general. I was a lurker on reddit and have just now created accounts on Lemmy and Kbin. I find these two platforms engaging, even though they're small. I'm trying to engage more, not just lurk on here. I like the new communities on here, and I want to be a part of them. P.S. I still haven't gotten the hang of Fediverse, completely.
