All the bubbles you have pointed out have sprouted from the latest revolution: the information revolution. Did it start with the transistor or the computer? It doesn’t matter, it’s part of the same technological progression.

So what’s next in the IT world? My guess is that compute power is only going to get higher, faster, more efficient. If we can manage to make chips on a diamond substrate instead of silicon for instance, the thermals dissipation gains will be absolutely huge.

The next bubble is going to be about how to use that huge amount of compute power with no tangible added value for the common people, just like cryptos, NFTs have been. (It’s unclear to me if AI is adding value or not).

Metaverse has already died before being born so I can’t bet on that anymore. Like others have said, maybe something related to quantum chips though my previous thought makes it dead on arrival as well.
