I agree. The benefits of Bitcoin started and ended with one thing: removing the middleman. We're seeing its real benefits in war or sanction contexts. If I want to move money from one country to another, without any KYC bs, my goto is Bitcoin and it has worked for me for the last decade. As a store of value, I'm not sure if its good, but that's secondary. So its kind of a niche thing and frowned upon because people will also use it for "bad" things, i.e., ransoms, terrorism, buying drugs, etc. But for me, a degree of crime is necessary for a healthy civilization.
All the crypto killer apps lost the plot, especially NFTs.
As for LLMs and more specifically, ChatGPT, they are not a niche thing so I agree in that their potential is way bigger. I'm not yet sure what that is, but I think it will change things profoundly. Replacing Google/SO is just a side effect of something bigger. But that's just my humble opinion.
