It does matter whether something is useful and I really wish people would stop making comparisons to crypto because it's an absolutely terrible comparison.

AI is certainly in a bubble right now, as with dotcoms in 1999. But AI is also delivering a lot of value right now and advancing at an incredible pace. It will become ubiquitous and at a faster pace than the Internet ultimately did.

Meanwhile, Bitcoin has been around for 17 years and there still are no non-criminal use cases apart from buying it and hoping it will be worth more in the future.
