So many people want to say there isnt a bubble because AI is real/good tech, they're wrong, as both can be true at the same time.
Bubbles are about investor behavior, and not the tech itself.
Look back at the internet in 99, even when the bubble popped, the internet didnt go anywhere & kept getting better.
Some considerations that many folks seem not to get:
1. It can be a bubble even if the tech works. (For instance, if the tech doesn't have a high-demand use case.)
2. It can be a bubble even if the tech works and has strong product-market fit. (For instance, if the tech cannot be economically viable.)
3. It can be a bubble even if the tech works, has strong product-market fit, and has a path to eventual economic viability. (For instance, if profitability takes too long to achieve or makes margin/competition assumptions that fail to materialize.)
4. It can be a bubble even if the tech works, has strong product-market fit, and is currently highly profitable. (For instance, if demand has a hard ceiling and growth stops once the ceiling is reached.)
5. It can be a bubble even if the tech works, has strong product-market fit, is currently highly profitable, and has unlimited future demand.
Literally all it takes for something to be a bubble is for lots of people to over-enthusiastically bet their money on it, and subsequently get panicky.
Importantly, bubbles can be attached both to things that are completely hogwash, like the Metaverse, and to world-changing developments like the Internet or railways. Bubbles don't care. They're brought into existence by the thoughts and feelings of investors, not by actual tech or products.
"The bubble has burst" doesn't mean "the tech didn't work" or "people stopped using the tech." It only means that people got panicky, investor money dried up, and valuations collapsed. Internet adoption didn't stop in 2000.
