To say whether it's a bubble, we need to know the value of the technology. The value of modern AI seems very high. That nobody knows how high, that they still haven't figured out applications, and that the technology and its tools are still far from refined, is normal for any new technology. If you add the value of the potential political power gained by controlling AI, then the value to the owners and investors is a…
How that washes out on net we'll have to see. I'm not gonna pretend I know more than anyone else. Just keep in mind that a major difference between now and 2000 is companies stay private a lot longer. An IPO forces you to open the books and sustain public scrutiny of the broad investor class. A still-private startup only needs to convince one funder of their value. That inevitably leads to higher variance and a greater risk of failure. That doesn't mean the whole sector is necessarily a bubble, but if it is, it can be sustained a lot longer without us knowing. A small number of people with $50 billion they need to park somewhere and no other obvious options can keep shitty ideas afloat in a way that wouldn't be possible if they had to be subjected to broader exposure. We like to believe people with $50 billion can't be wrong, but the wisdom of crowds always beats the wisdom of individual genius.
Heck, AI itself taught us that same lesson!
