Don't get me wrong, self-driving cars are the human advancement that I am most looking forward to.

I think they will both be extremely big changes in different ways. Autonomous cars will be one big impact that indirectly touches many industries. Robots are going to get into everything, and the world will look very different at the end of it.

Robots will do farming, cleaning, food preparation, fire rescues, surgery, manufacturing. Basically, whatever parts of the world software can't eat, robots probably can.
