For years I thought Mickey Rooney (1920-2014) and Mickey Rourke (1952-present) were the same guy. I’d see Mickey Rooney in a movie and be like “Wow, he’s looking pretty good for his age,” thinking he was a man 32 years his senior and/or dead.
I finally twigged when I eventually saw Iron Man 2 (2009) and was like “How is he doing this?!” and actually looked him up.
This makes me wonder if there are any exceptions, things that brains didn’t name. Onomatopoeia seem like a good starting place (and maybe ending place). Did we name cats’ meows meows or just hear them and go “OK, that’s what that is then”? Cat brains didn’t name them that either, they weren’t thinking what they should call the sound they make, they just made it.
As far as things which name themselves, I can’t think of anything else but sounds.
The adjective for this type of music is “diegetic”. That’s sound which is occurring and audible in-universe, not just to the audience.
Even though there is some network effect just in terms of there being much less content on the threadiverse than Reddit, I do feel like this is something we’re somewhat shielded from. For the most part, we’re not here to follow specific people: my friends aren’t on Lemmy/Mbin, or maybe they are, I don’t actually know or care. I have a Mastodon, but a lot of the people I’d theoretically be interested to follow are still on Twitter, or BlueSky, or Threads or something. It’s not enough of a pull factor to make me join any of those, but it’s probably why I barely use Mastodon.
