UBI is the only one that makes sense to me. There has to be a domestic market of people buying stuff for the rest of the economy to exist. If all the people are automated out of jobs, then that domestic market has to be provided by UBI. The funds for that provision have to come from corporate taxes. Probably a tax on capital spending or depreciation - if you're replacing labour with capital and the government relies on taxes on labour for its revenue, then the government has to switch to taxing capital. If there was a way of not involving the government in this, that would probably work better. The dream, of course, being The Culture - no government at all, just people acting in their enlightened self-interest in a post-scarcity world.
