It's basically the reason this bubble not only exists but has a chance not to pop : there is so much stock value in it that the big tech all want to keep feeding it, and they're sitting on so much cashflow they can afford to do it

It's absurd, but that's where it is. And a company like OpenAI basically hangs on it, because they have obligation almost ten time their revenue and the only way this does not deflate quickly is if others keep feeding it cash.
