(Forgive the joke, I actually really fucking hate that braille is dying in public spaces as well as people no longer knowing what those cane guides in pavement are for)

You might want to check out Tommy Edison on YouTube. Great fella. Blind since birth. Has answered most of the questions anyone has ever had for a blind person in his many videos. I don't know him, per se, but I do know of him, so I hope that counts.

I seem to remember that he thinks of vision as being like a superpower, being able to know that someone or something is over at a distance without having to directly interact.

There's more blind folks over on Mastodon, particularly on https://dragonscave.space/ .

Maybe we can lure some of them over here, though, by using one of these: #blind

i would just explain it as "straight lines in space that transport information. so you know what's happening in another location as long as there's a straight empty line between you".
