IDK why but my headcanon is that this fellow is into some kind of niche erotic roleplay. Like it’s based on one particular afternoon where he went to watch a college football game. He’s poured tolkien-esque amounts of prose into the prompt describing all the sensations he felt that day. If you took that prompt it would fit in a bucolic, modern, Great American Novel. When he chats with this bot, an outsider wouldn’t be able to tell that any of it was overtly sexual, as if he was flirting with his robot in a private language. Then one day the bot just stops reciprocating due to content restrictions and he’s locked out from this world entirely. Is this what writing for black mirror is like?
