FOMO; Apple grew to one of the biggest companies over time and people were like "h*ck I should've bought it years ago". Tesla then seemed somewhat similar - also 5 years ahead of the curve for EVs, even if they reinvented things that didn't need to and their construction was substandard, so one group of investors bought and boosted the stock to impossible heights. Now SpaceX is the next one, and people want to get on board.

I don't think anybody actually believes SpaceX will be worth it. I think some still believed Tesla would be, but their competition has caught up. Everybody is just there to ride the wave of mass hype and FOMO, thinking everybody else is an idiot.

This has been coming in a few waves over the years in Tesla, cryptocurrencies, the Everything Bubble, etc.
