I agree with most of what you've said here, yet I do see the killer application for both Ai and Bitcoin put together. It has nothing to do with profit.
Ai actually is a brilliant controller, driver, flier, much better than any human, there is lots of proof to show this. And it knows how to learn to do anything that can be learned, including how to weed out bias in its data, and how to evaluate and accept new data.
To me it looks like the perfect grand system controller for the solar hydrogen ecology we seem to be being pushed towards by nature.
Even better, this includes also the killer application for Bitcoin.
Bitcoin is the first ever implementation of money as solar energy, interchangeable with fuel as solar energy.
Generate those in every community solar installation and not only are all financial, energy, water, food, climate, poverty, colonialism, criminalism, actually any and all problems fixed, but in addition we will see long desired technologies lost or never started, coming to reality, including genuine cure for cancer and immortality research, and we will pick up all technologies found to be benificial but unprofitable previously.
Concorde flying again on hydrogen is something I would love to see.
Anyway, the data indicating this is happening is there.
To see it, we just need to drop the for- profit mindset, including the Bitcoiners
I think we are getting close now.
