I love the article, but I disagree with your conclusion.
I don't believe jobs are our reason to live. The economy is set up in such a way that we have been forced to believe it is.
At the end of the day, if we have enough resources and time and we are left to our own devices, we will be able to concentrate on the finer things in life. This could mean spending more time with family, having bigger families, spending more time on innovations, etc.
Also, this automated environment will require a butt-load of engineers to maintain. There are also a bunch of other positions required for machine maintenance.
Most importantly, left to own devices, rather then losing a reason to live, I believe we start looking into discovering new things, like re-invigorating our space program.
Either ways though, very interesting read. Thanks!
