The OP compares the current LLM hype to crypto, but I think it's more fair to compare it to the dotcom bubble. When a new, interesting technology appears, there's always a lot of hype around it - I think it's natural. People are still figuring out what works and what doesn't. Naturally, some overoptimistic people overhype it. The dotcom bubble burst; nonetheless, the internet is now an integral part of our lives. Despite the hype, crypto was always a very niche area, while currently even my grandmother uses ChatGPT - just like the internet.
