Musk has enough money to single-handedly pay for the costs of running twitter for the next few centuries, and nobody in their right mind would actually let twitter be “killed”.
I dunno. Weird that he said it like it was going to happen, then, instead of saying he wouldn’t let it die. But he says a lot of weird stuff, so maybe this is one of those cases where we’re supposed to assume he’s just saying gibberish that doesn’t mean anything.
But maybe he was joking. Sure didn’t seem to be, but who knows. Or he’s wrong.
