I don't see it like that. At least in central Europe (mostly radiating out from Germany) there are a lot. I mean, just look at the Hackerspaces.org list…
Also, Hackerspaces don't exist in a vacuum. Money is tight, which usually means dwindling membership numbers, which leads to closures. Those complaining about disappearing Hackerspaces are usually those who weren't members.
Algorithms in Mastodon are rather unlikely, for a couple of reasons.
I personally like it that way. I prefer that it feels like a Social Network, not something harvesting my attention. My algorithm for finding new accounts to follow are the recommendations of those I'm already following based on their retoots, as I trust that judgement more than that of some unclear algorithm that can be played by clever keywords.
From the article:
He continued to elaborate, saying, “We trained the system–‘Hey don’t kill the operator–that’s bad. You’re gonna lose points if you do that’. So what does it start doing? It starts destroying the communication tower that the operator uses to communicate with the drone to stop it from killing the target.”
Mastodon. Wie gesagt, ich bin nur im Fediverse unterwegs das klassisch sehr links-liberal unterwegs ist.
