"The point you're missing is that robots are going to making the A/C work. And other robots will be servicing the robots. In the not distant future we'll have robots that are simply faster, stronger, less error-prone than humans when it comes to doing *any* kind of physical task. We'll also have software that's simply faster, smarter, better, less error prone, and more capable than humans when it comes to doing *any* sort of cognitive or knowledge based task. In such a world, exactly what jobs will be left for humans to do? Not driving trucks or taxi's. Not mining. Not flying. Not medicine. Not restaurant service. Not manufacturing goods. Not farming. Not administrative tasks. Not accounting. Not janitorial work. Not wiring or plumbing or HVAC or construction. Not when there's robots that can do all that and more, better for nothing. There's just not going to be enough work to go around. Certainly not enough work with enough value that everyone can put in 40 hours and get out a living..." - Eric P
