approximately 10% of Singapore's workers are robots. We as smarter, wealthier nations should be able to significantly reduce if not eliminate most menial employment. Of course it should be said that robots don't earn a wage and pay taxes so I wont pretend the government has any great incentive to see such technologies implemented.
More importantly it shows the gains when already massively parallel (and perhaps on a single or dual core you don’t get as much gains as it doesn’t matter that the CPU has to go in order when you only have a few).
