TBH, this feels like some kind of psychotic break. He just kind of stops posting out of nowhere. On twitter there are some attempts from others to reach him that seem concerned for his wellbeing: https://x.com/DanielleFong/status/1866211089660477490
26? I was thinking schizophrenia as soon as I heard the age. The weirdness of the situation, unclear motive, and how it seems very out of character all scream onset of some kind of mental illness yes.
Some say he had a medical issue and saw first hand the reality of being sick and not an elite in America (even though, by all accounts he probably had good insurance and was quite wealthy in his own right).
I wouldn't be surprised if he went on an adderall bender that he never recovered from. Adderall and rabbit hole topics without a resolution (societal change) are not a good mix.
