At some point or other, industrial automation will reduce employment. The best the unemployed then can do is to survive on charity, die or go to some lone place and set up their own small economy.
I think you are on some implicit assumption that somehow all work will become automatized and it will be something like computers and/or robots will do all the work. Conceivably, computers and robots will even build the computers and robots which will do all work.
This of course was the fantasy nightmare envisioned in the early years of the computer revolution. You don’t hear much about it anymore because it has proven to be completely false. Even though computers have become widespread both in business and the home, enfusing our entire culture, not only hasn’t it reduced employment, it has vastly increased it - mainly by opening up entirely new industries and employment opportunities which were probably impossible to envision as little as 20-30 years ago. Just consider, as one example, the number of people who are involved today in the Internet which barely existed 20-30 years ago. Look at companies like Amazon.com (plus 1,000’s of others) which have grown up entirely connected with the Internet and wouldn’t exist without it.
Even if you had very advanced robots which could perform many of the mundane tasks of our existence, such as house cleaning or mowing the lawn, someone will have to program them, teach people how to use them, repair them, sell them, etc. And once you have one model of robot, people will want other models. They will want them in every conceivable shape, size, color and capability, just as they do now in other similar categories.
And just as it has in the past, as our standard of living increases as a result of this increased automation, people will have more money and leisure time and will look for ways to enjoy their lives with it. That, too, will create new industries - perhaps in the future interplanetary space travel. But the one thing you can be sure of is that it will create new industries that you cannot even envision right now. It will be a complete surprise.
People’s wants are virtually unlimited. No matter how many of them you satisfy, they can always want more. The average middle class person today lives in a state of unimagined luxury in comparison to the average worker 100 years ago. And yet how many of those middle class people can’t give you a list a mile long of things they’d like to have or do with their lives if they had the means to do so?
That will be as true 100 years or a 1,000 years from now as it is today.
