Ehh, the short ratio is still over 100%, and I guarantee you those aren't retail investors. So plenty of institutional investments to stick it to left.

You don't know when those shorts got in. The price is clearly too high now, so it makes sense that sophisticated investors (probably other hedge funds) would be entering short positions at the recent prices. And those recent entrants will not be squeezed unless the price goes up by another ludicrous amount, which it is less likely to do now that the initial surge of enthusiasm is running its course. So lots of retail traders who got into the frenzy late with normal stock purchases at these absurd prices will get screwed during the inevitable crash, while the recent shorters will make a killing.

I don't think the initial surge of enthusiasm has run its course. Most are stuck trying to find another place to buy in due to RobinHood closing off purchases.

We'll see won't we?
