Shem, I could not make the pro-UBI argument you made any better.  Well done!  

I hope skeptics inclined to think such a future scenario is just a figment of your vivid imagination will feel free to say so, because I could then flood this discussion with the rapidly growing mountain of evidence suggesting tech change could eliminate existing jobs faster than it creates new jobs--or at least "good" new jobs.  Such evidence is abundant and not difficult to find.

If no readers ask for this, anyone who is interested in the growing threat/opportunity of 21st-century "technological unemployment"--i. e. a near-future scenario (the next 20 years) in which the local, national, and/or global demand for jobs gradually and increasingly exceeds the supply of jobs (that only humans can still do)--can learn more by reviewing the MANY sources I've shared about possible tech unemployment on several local FB pages, including Civil Beat Politics, Politics in Hawaii-Think Tech Hawaii, and my own FB page.
