It was true of the Industrial Revolution, it was true with the rise of computing, and there’s no reason to believe it won’t be true with the proliferation of robotics.
But go ahead and ignore economic history if you’d like.
We are in uncharted territory and a paradigm shift. We have more people every day and less good paying jobs. The industrial revolution needed more workers to m eet m ore demand. When you have robots and drones providing the labor they jobs created will be less than the jobs lost.
Re: “there’s no reason to believe it [new jobs for humans] won’t be true with the proliferation of robotics.”
I can think of two reasons.
When affordable machines become as agile, or as intelligent, as the average person, 50% of the work force is going to be unemployed.
That will take decades, but it is going to happen, and within this century.
The good news - robotics and Artificial Intelligence will create unprecedented wealth, unemployment will lose its stigma, and welfare will be increased until all Americans enjoy a modest, but completely secure, standard of living.
