G-Train, I think that's an exaggerated stat. In the US, the top "1%" own 38% of the wealth. That's a lot more unequal than other rich countries (or the US from the 40s-70s), but it's not even in the same ballpark as the nightmare scenario I described.
Yeah, we actually have no idea if the jobs potentially taken by robots will be replaced by anything ... Much less by jobs that can be performed by the millions (or billions) of average people whose labor would be displaced.
There's no law of nature preventing us from ending up in a world economy with 100 trillionaires and 50% unemployment.
? We have decades upon decades of technology growing at an exponential rate. This isn't a new phenomenon, it's just that the rate of growth is growing so we will see change happen at a faster rate.
What do you mean by "technology growing at an exponential rate?" We certainly don't have any history that remotely resembles robots taking high skilled intellectual labor en masse.
The point is, if robots obtain general intelligence and can be mass produced, there goes your white collar service jobs. It's difficult to see how you would need an army of white collar professionals to guide the robot, in the same way that we currently need an army of people to handle technologies.
That scenario is nothing like a horse-whip company going out of business because it's replaced by a company that manufactures car parts.
Also, if self-driving cars replace human drivers, that alone eliminates a giant swath of low skilled jobs. I haven't heard any viable plan to replace those jobs if they are eliminated.
