My point is that it's the same old unfalsifiable, adolescent speculation that every teenager of sufficient nerdiness or THC intake has had at some point. We're broadcasting these ideas, not because they're at all new, or interesting (they've been around for about 400 years, at least). We're broadcasting them because Elon Musk is saying them. His only new idea, AFAICT, was asserting some probability that he pulled out of his ass that this idea is false. In the absence of new ideas, maybe we weight this by the authority of the speaker. If a theoretical physicist said this stuff I'd be more inclined to take some kind of notice (since they'd have a deeper insight into the structure of the universe than I do). A car salesman - not so much.
