Stablecoins have decent use cases and have100s of billions locked in them. Right now Tether is mostly reliant on Ethereum, which makes it fairly risky. I'd prefer to keep Bitcoin pure, but Tether could help spread Lightning use drastically. Tether used to be on Bitcoin L1 before and moved away from that - perhaps Lightning is a better home for it. I'd trust it more, too.

AGI will still not have happened. The AI bubble currently gives the impression that Artificial General Intelligence is just round the corner, but there is still a massive hurdle between smoke-and-mirrors LLM projects vs actual sentience, reason, creativity, and critical thinking.

However, Robots will be relatively commonplace, doing super basic tasks, flipping burgers, construction, cleaning etc, with limited/remote supervision.

Bitcoin will have enabled much more of the 'Sovereign Individual' thesis to come true. Wealth inequality will increase but overally productivity and general freedom will be at much higher levels. The welfare state will have shrunk massively, and the world will be much better.
