Maybe, but what is the point of having all that wealth if only 10% of the population can access it?
If automation replaces 90% of jobs, then you're going to have a lot of unemployed people with no money.
I disagree about automation becoming a commodity. Automation is all about monopolies. You only need to write software once and only the company with the best technology will control the whole market... Why would a consumer use a piece of technology if it is less efficient than a competing piece of technology?
Just look at Intel vs AMD. Intel's CPUs became just a little bit faster, and as a result, in just a few years they decimated AMD financially.
Technology is a winner-takes-it-all game.
