I don't know anything about finance, but how credible is Elon Musk in this regard?
I mean to be fair he does say that this is "total speculation" and a "guess" (which it is). So why is it news worthy? I think if you're so rich everything you say is published somewhere, but Elon Musk didn't become the richest man in the world by predicting economic downturns so I would be more cautious when "guessing".
