replace those jobs with robots.

I agree with you here, there is a delicate balance in capitalist societies.

If you automate all of the workers and there are none left, then you have no-one to sell products to and companies go under. Doesn't matter how many robots you have making your products, if you have no customers.

The issues I expect to see from Automation are similar to the sort of problems we're seeing through our current iteration of capitalism - inequality. Automation and robots may speed up the process, but at some point the people that have no money and no prospects will find a way to get by, it may even involve violence.
