A warning from Bill Gates, Elon Musk, and Stephen Hawking on Automation and Jobs

So automation and technology is displacing jobs. What are some ideas these leaders propose:

Bill Gates recommends we tax robotic workers so that we can recapture some of the money displaced workers would have paid as income tax.
Elon Musk recommends we adopt universal basic income and give everyone a certain amount of money each year so we can keep the economy going even as millions of workers are displaced by automation.
And I recommend we take some of the taxpayer money we’re using to subsidize industries that are now mostly automated, and instead invest it in training workers for emerging engineering jobs.

Larry Summer’s disagrees with Bill Gates and argues for:

invest in more education and retraining programs. He also suggests that direct government employment programs and wage subsidies for some groups of affected workers would be welcome.
