Great post and a fascinating topic. I am really interested in UBI and how it could really change our approach to work as well care giving, and volunteering. I agree with you that UBI would greatly streamline government administration and this would create huge cost savings on administration of social services. I do also think that certain stages of life are more expensive than others and it would actually make sense to create a UBI program that is responsive to that rather than just a flat pay out. The one uncertainty in the narrative is where does the money come from? If UBI is a response to mass unemployment or more part time employment then it seems plausible that Governments will experience a marked decline in the revenues they collect and if revenues decline how can they afford this pay out without dramatically raising corporate tax rates and tax rates on the wealthy? I'm not opposed ideologically to either of those solutions but figure this will just lead to corporations moving out of countries with UBIs to find locations with lower tax rates. I wonder if, as Bill Gates suggests, taxing AI and AI driven devices could help shore up revenue?

Look forward to continuing the discussion on this!
