Both things can be true. The tech can be transformative, and the current valuations and burn rate can be wholly unsustainable in the short term. This is exactly what happened in the dotcom era.
Whether or not this one is the same is impossible to know until after it happens. But there are credible arguments to both sides.
This is a small handful of companies absolutely dominating the bleeding edge in an extremely high value technology that has value in nearly every other market. There's a lot of misses with companies implementing LLMs, but there are a LOT of companies that are using LLMs to deliver massive value that was impossible 3 years ago.
LLMs are not, in fact providing much value to any other markets. And the amount of value they would have to provide in order to pay back current costs is staggering. It's a bubble. There is no way any of these companies is going to break even.
