[quotemsg=19421570,0,783707]Yep -- automatic looms will make everyone unemployed. Oh wait wrong century ... Luddites don't change ... There will professions we can't conceive of now, because we have no context for them.[/quotemsg]The problem is that the industrialization reduced the need for manual labor, but created opportunities for knowledge workers. However, as computers start out-competing humans in the knowledge economy, there's nowhere left to go.
Just take the example of self-driving cars and trucks. Millions of Uber, taxi, bus, and truck drivers will be put out of work, but only tens or hundreds of thousands of jobs will be created by the self-driving vehicle industry (and that's including both the people who design, build, and service them). Otherwise, it wouldn't offer an economic advantage.
And it's not just drivers that'll be put out of work. Consider the number of people employed reviewing contracts or doing transcriptions and translations. There are lots of skilled jobs that are starting to get replaced by machine learning, and quantum computers will only hasten that trend.
If you look at the low cost of labor in most of the world, one could argue that an oversupply of labor already exists. It will only get worse.
