AI/ML barrier to entry is far simpler and vastly user friendly compared to crypto. Instant value return or gratification from ML products (GTPs and rest) is far more mainstream friendly.
Another view is the "loss" factor. Nobody, thus far, has has had their funds stolen or lost using ML products. I understand content creators and those who, unwillingly, contributed knowledge to learning systems did get circumvented but i'm talking about users/customers. Compare that to the negative stigma of crypto frauds and stereotypical association to illegal transactions.
Apples vs. rotten oranges in my opinion!
I'm a crypto sceptic but I wasn't always like that. There was a time many years ago when Ethereum was brand new and I was an eager early adopter. I tried creating wallets, tried running a node to see what it does, put in some money through an exchange, and then... Nothing. There was nothing to do after jumping through all those hoops. In fact, turns out the only thing to do with the crypto wallet was to wait for its value to maybe increase over time. (Hence the "number go up" meme.) And for that to be realized, I would need to sell the coins to a new sucker to get real money out again — suspiciously pyramid-like.
And it's still like that today. There's no reason for me to ever open those old wallets again (and surely I don't even have the passwords anymore because self-custody is such a terrible idea UX-wise). And there's no reason to try any of the new stuff because it still obviously does nothing I'd need.
The early Internet wasn't like that. There was plenty to see and try, and interesting people to interact with. Once you tried it, you probably wanted to go back.
Today's early AI is like the early Internet in all the ways that crypto isn't and never will be. There's plenty you can do with ChatGPT and other models, right off the bat. You can install interesting stuff locally or run it on somebody else's server. You don't need to run the crypto-style terrible UX gauntlet and buy coins from a shady operator. AI is already so much easier and more useful and more powerful than crypto-web3-anything, it's competing in a completely different race.
OpenSea has lost 99% of their transaction volume in the past year, and even more of their revenue. I'd be shocked if the same happens to OpenAI. One was a fad, the other isn't.
