On the one hand, I want to believe Scott Adams succumbed to some diagnosable degenerative mental illness or something. I used to enjoy Dilbert comics/media. (Anybody remember the animated series?)
On the other hand, even reading old Dilbert, a bit of me is always like "ok, yeah, in retrospect there's a disturbing undercurrent of xenophobic right-wing BS going on here". Maybe he was always like this at least to some degree before the Qanon brainworm devoured what was left of his connection to reality.
