Do you believe it’s sensible to watch your neighbors starve, because they’re more expensive to employ than a machine? Oh wait on, you already use bots to make money, silly question.

When robots can produce a product the price of the product will fall to the point where more people can afford it, even though there is less work for humans left to do. It is easy to see why. With robots doing work the society as a whole gets richer and not poorer. Given a stable demand implies that the price will necessarily drop.

There are many examples of this. Take sharpies for example. They are essentially for free.
