There’s also that moment in No Man’s Sky when you figure out what the story is implying. I’m being vague here to not spoil it for anyone. But it doesn’t have a single point in time where you piece it together. There’s a growing amount of evidence before the game outright tells you what’s going on.
The cult of personality thing is the big part IMO. If it was just him being a piece of shit without any influence, then whatever. But he has a cult following that are influenced by him and his actions (plus Twitter seems now designed to push his thoughts). It’s important that the vast majority of people understand that Musk is an idiot and a piece of shit. It needs to be lame and gross to like him.
