Could AI companies just survive perpetually forever using investors' money?

It just seems unreal right now at how the supposed AI bubble has never come until now. Just 2 years ago, people would've thought it was improbably for Nvidia to hit past $200 yet here we are today. No matter what market downturn and even in Trump era 2.0, the AI stocks have just kept climbing up and up non-stop to ATHs despite constant losses and no profits.

It makes me wonder if this could go on perpetually forever. Because the way I see it, both retail and institutional investors are just stubbornly throwing money at these stocks non-stop anyway. It's kind of like Tesla's case, right? The earnings to price ratio makes no sense but the stock just keeps shooting up irregardless.

So if people keep believing in a stock regardless NO matter what --> stock price keeps increasing as people keep blindly buying --> company survives by constant dilutions. Isn't it a way for companies to just go on forever with this kind of funding?

In the end, could this be a new way for companies with zero net income to survive forever? If you look at Gamestop, it's the same thing. The stock has never gone below $20 because a group of retailer investors refuse to sell no matter what so the company can perpetually stay afloat forever.

There's the old saying that "Wallstreet can remain irrational longer than you remain solvent" but what if the new saying should "Wallstreet can remain irrational forever if they want to." After all, this is no longer like the past where institutions dominated the money flow. Today, literally everyone and their mommy and puppy are investing into stocks and these people dont give a damn whether the company is actually making money or not.
