"no use case" and "no new tech" are just vague opinions that are typical anti-crypto talking points. Whether you personally like the use cases or not, obviously they are there as it's been on fire for more than a decade now, and continuing to grow in popularity. And regarding tech, there is no doubt that the advent nakamoto consensus algorithm is an absolutely breakthrough technology that will be seen as a pivotal moment in the history of tech, for better or wrose.
You are suggesting that there is an alternative. What perchance might that be? Some authority figure or organization that decides whether something is useful?
The same can be applied to your comment of "Crypto doesn't really solve a problem that needed solving". That's not an axiom, thats a subjective opinion, saying its not useful because it's not useful. Plenty of people will, and have, argued otherwise.
I didn't say it's "useful because it's useful". It's "useful because it's used by many people". Unless you are implicitly agreeing with me that the definition of useful is that many people use something and find value in it.
