There's still a significant barrier to entry to get involved with blockchain and most people don't even know what it is.
LLMs on the other hand have very low barrier to at least use- one can just go to google, ChatGPT etc and use it and see its effectiveness. There's a reason why in the last year, a significant portion of school students are now using LLMs to cheat. Blockchains still don't have that kind of utilization.
Honestly I think that makes the argument stronger though that it’s unfortunate they jumped on.
