It's a cute analogy perpetuated by GenX VCs and crypto-wonks who don't see a down-side in making bold, wild claims. It's one of the many problems today in which there is no down-side risk on making extremely early predictions. No one will call you out on being wrong. I view it similar to people who have been calling for another tech bubble and the subsequent market crash even though we're still very much in the midst of consistent All-Time Highs.
