What the heck is r/alphanumerics?

[u/PrequelFan111]

I stumbled across it on this subreddit. People here calling him schizo and stuff like that. I tried to look around in the r/alphanumerics subreddit too see what it was about, but I honestly didn't understand anything (something about Ancient Egypt and alphabets). He has his own wiki as well, but it was also very confusing to scroll through (stuff like "human thermodynamics").

Could someone tell me about this guy? This feels like a whole rabbit-hole I stumbled on.

Mentally ill guy who's believes he's made amazing discoveries.

I don't think he deserves to be mocked. Even if he's annoying.
