I'd argue that the last year or so of Tesla was the first major incarnation of this gamma squeeze + memes to burn short sellers but yeah GME is a while other level.
In the extreme case this could be true of almost any company. Imagine if GME were just a shell and a brand. Then they raise money, get a great board, hire industry experts, and go... whatever.. compete with Steam, turn the physical stores into e-sports venues, pivot to game development, whatever. Use the money to get the expertise, and you already have the brand and attention, which is now worth a lot more. That is kind of what happened with Tesla to some extent, although they already had a great brand a genius owner.
This GME thing is just one little piece of an overall new zeitgeist. I'm not about to even try to predict the next crash/bubble-pop, though. I just don't have the stomach for this kind of market. When a change comes, it may not happen in a predictable way. I think there's at least a chance we could somewhat be in uncharted territory here.
