The benefit of the fediverse is that it’s trivially “forkable”. If lemmy.world and other big instances get overwhelmed with bullshit, I fully expect that many smaller chill/focused instances will defederate and keep on doing their own things, chatting only with each other. Perhaps there would also be some in-between, instances which are federated with both worlds, and where you can get a combination of tons of niche information/entertainment but with bots, and a small amount of genuine human interaction. I hope if that ever happens, lemmy-the-software gets sorting algorithms to deal with these situations.
