> a few years ago people were telling me that crypto was going to replace currency, and soon every person on the planet would be using it for every transaction. Many people believe that will still happen, but I don't think many serious people do.

As you say, that is a weak counter point. I do get what you're saying, but crypto flaws were built in from the start:

- Deflationary currency isn't going to be spent, it is going to be hoarded, if it would have any value at all. The design was self defeating from the very start.

- Technical limits of PoW. Obvious right from the start, which led to the block wars. PoS "solves" that but with other costs. And it still doesn't solve the first point.

Despite these, crypto did get adopted, just not in any way that crypto maximalists said it would. It got hoarded, as expected.

But the real test is: If crypto disappeared tomorrow, would the world notice or really care? I would argue, apart from people losing money, most of the world wouldn't even notice it was gone.

There is no way you could say that for LLMs.
