Microsoft invested $10 billion in Generative AI (that we know about). As far as we know, they invested nothing in NFTs. Google has been using Generative AI for years, and rewrote their entire Google I/O keynote to talk about it. They've spent billions on it. As far as I know, they spent nothing on blockchain. Amazon has already pre-announced support for Generative AI in AWS. They actually do have a blockchain product, but they certainly don't hype it like they do their AI product. And since they've announced they are building their own foundational model (Titan), you know they are spending at least a billion dollars building it.

So sure, maybe it's all hype, but the big tech companies with the money are certainly putting their money behind AI in a way they did never did with blockchain.
