> where would the income come from

You are confusing money with wealth (stuff people want). The money would come from the government, which can simply print it.

Take a hypothetical situation where robots cause the total amount of wealth (stuff) created, in one year, to increase by 100%. Now assume the government prints enough money to increase the total amount of money by 100%. In this case, wealth has increased by 100%, and money has increased by 100%, so people's ability to get stuff has increased 100%, with 0% inflation.

In the real world, things never work out so cleanly, but the above offers a simplified model of what could happen.

Why would there be zero percent inflation, if the money supply doubled?

At the risk of being simplistic, because so did the "stuff" supply. Inflation is when the money supply increases without the stuff supply increasing, so each dollar is worth less stuff.

It is worrisome that the posts which are factually accurate are getting downvoted. This raises a question about economic literacy on Hacker News. Presumably the people downvoting this comment simply don't understand how the economy works.
