Bill Gates's Robot Tax Is a Terrible Idea

I wonder if a younger Bill Gates would have supported heavy taxes on his company's computer software that allowed 1 accountant armed with a spreadsheet to displace the jobs of, I don't know, maybe a dozen experienced accountants using paper?

Surely, society is so much worse off with so many workers being displaced because of all of this technological progress created by Microsoft and others and being denied of so much extra tax revenue?
