> can someone tell me the actual market size for technophiles who I think are only people who use this stuff?

Approximately zero. Grifters, FOMO driven technophiles, and wannabe "founders" jumped on the bandwagon because it was "the next big thing" (where did I hear that before?). Now that the creator got cushy job at OpenAI, and the hype is over, it's just another tech bro toy to burn tokens with and scratch your OCD.
