There's a lot of similarity in tone between crypto and AI. Both are talking about their sphere like it will revolutionize absolutely everything and anything, and both are scrambling to find the most obscure use case they can claim as their own.
The biggest difference is that AI has concrete, real-world applications, but I suspect its use, ultimately, will be less universal and transformative as the hype is making it out to be.
The AI sphere isn't like crypto's sphere. Crypto was truly one thing. Lots of things can be solved with AI and modern LLMs have shown to be better than remedial at zero shot learning for things they weren't explicitly designed to do.
But modern tech isn't that and doesn't have a particular promising path towards that. Most of the investment in heavily scaling up current hardware comes from a place of not understanding the technology or its limitations. Blindly throwing cash at buzzwords without some level of understanding (you don't need to know how to cure cancer to invest in medicine, but you should probably know crystals don't do it) of what you're throwing money at is going to get you in trouble.
