There were bubbles about things which were promising profits in the future but at the moment nobody knew how exactly. Like the dotcom bubble.
This one does bring profits now in its core too, but that’s a limited resource. It will be less and less useful the more poisoned with generated output the textual universe is. It’s a fundamental truth, thus I’m certain of it.
Due to that happening slowly, I’m not sure there’ll be a bubble bursting. Rather it’ll slowly become irrelevant.
