I'm going to say something that triggers people on HN (because it involves creating our own currencies, like berkshares, bristol pounds, etc.)
Here goes. Our towns and cities need to create our own money supply, especially to survive the coming depression (Both Keynes and Hayek would agree). The vast majority of our money is currently issued by banks, which have exactly the opposite incentives, they will issue less credit and on worse terms the more you need it. In fact the banks love to lend to the ultra-rich (including the guys who pay $0 in taxes and use their shares as collateral, while having their corporations buy back the stocks).
If you want to tinker around the edges, keep using their money. But in a world where AI makes everything cheap, why not have communities roll out their own money, and pay UBI in it? Waiting for the federal government to issue UBI is a fool's errand (not even Nixon was able to get it done, as president, much less someone like Andrew Yang who I supported and built campaign apps for, http://yang2020.app).
The community acts as the source and the sink of the money. And since we don't want to "trust" any given member of the community to operate the database, we need... a blockchain. I know, this is where I will get heavily downvoted for mentioning that (I have a feeling that there is even keyword matching to do it automatically). But... what is the alternative?

The alternative is that people keep relying on giant corporations to give us jobs, and on giant banks to issue our money supply, while they just siphon more and more money to the rich. But any time someone says "hey, we have the technology to self-organize and serve each other" there are people frothing at the mouth angry at this person. Frankly, towns could build socialist cooperatives for everything, e.g. their own Uber without the shareholder class taking most drivers' salaries. AI makes it easy. But the main thing is making our own money supply, and giving it out as UBI to each citizen to spend on food, robots, etc.
So bitcoin, but without calling it that because of the political implications.
