I mean, regional instances don’t have to stop folks from engaging primarily with interest based communities.
Some regions will dominate certain interests for example - here in Tucson we’re consider one of the Amateur Astronomy capitals of the world. If mander.xyz were to disappear tomorrow, Tucson would make a good home for all of the fediverse’s astronomy needs even though its a region based instance.
Further, there’s nothing that states an interest-based instance needs any registration. One could imagine a world where local instances have all the users and identities, and the interest based instances simply provide communities to the larger fediverse with no users of their own.
But yeah, it’s definitely a paradigm shift that makes interest based communities a bit more difficult to find.
I liked it just fine!
I know there are a lot of Asimov diehards that found it disappointing. I don’t know why. The iRobot book wasn’t even really a book, it was a collection of short stories. Not exactly an easy thing to adapt to a movie.
