Even stuff like the Steam Deck can play emulated Switch games, and that’s an x86 PC, a machine with a more similar architecture should absolutely have no problem with it.

AFAIK, Mastodon actually did gain a sizeable amount of users that actually stayed, even though the number of users has dropped since the peak.
I personally think something like Lemmy works better than Mastodon, since content is more important here than the users, which I think makes it more easy to have a self-sustaining community.
