How do we actually FUND universal basic income?

This is the whole ballgame. Options, roughly best to worst in my view: (1) automation/AI dividends — tax the productivity gains that displace labour; (2) data dividends — you're the product, get paid; (3) carbon + wealth taxes; (4) sovereign wealth funds (Alaska, Norway). The most credible answer is a blend. The interesting frontier is community equity — what if people collectively owned a slice of the companies automation creates? That's closer to what's being tried here than people realise.
