Farming used to be a farmer for every four or five people. Now its more like 1:1000. That's been automated to an extreme.

Service industry is hard to automate - though we've done a good start with the dishwasher. Only 1 fulltime guy needed for every 100 people or so? That's pretty good progress.

So yeah, we'll always need folks for services. And we'll have to pay them well in future! That's seems a pretty good future to me.
