I say this half facetiously. When you think about everything that machines do and potentially can do, it has made manual labor by people relatively obsolete in almost every way. As we've pretty much automated ourselves out of the "hunter gatherer" way of life and have automated 90% of farming, our own laziness has been the beginning of our downfall.
The fact that even programming can be outsourced to other computers to write code, has made even high educated job earners dispensable. Machines can produce self made music, art, and blog all by themselves. Chances are you've read a computer generated blog this morning (this answer being human generated).
Plus the labor is just cheaper.
We have now created a method of self driving cars and machines that actually learn from doing. We have computers like Watson and Baxter that we've seen on television have competed against humans in Jeopardy. Even now, a human winning against a chess playing computer at its highest setting is comical.
The evolution of the computer and the machines is getting more sophisticated while we as human beings are getting stupider. Don't believe me? Fifteen years ago, if I asked you to tell me the telephone numbers of the people you called most often you'd be able to rattle those numbers off from memory. Can you do it now? No. Why? You have those numbers stored in your cell phone and you let that memory muscle atrophy.
Welcome to the age of Idiocracy. Should the machines gain consciousness or make the very logical decision that our existence is just wasteful, it would not be a problem to phase most of us out of existence.
Mankind is headed into one of two directions. Either we're going to head for a labor free utopia where all we need to do is enjoy ourselves OR a newly made industrial revolution where no one can afford to live because mechanized labor is the most affordable and our economy crashes with the exception of the top .01%.
The machines have taken our jobs and the only thing left is whether we can survive in this new information and labor free age.
