The Robotic Future

As robots take over more and more jobs, one big question I fear may be getting overlooked is: What do we do with all the current and future unemployable people?

There is a certain minimum level of performance required to be worth hiring at minimum wage. As the skill level and performance of robots increases, the minimum ability required to be worth minimum wage will also increase.

Math isn't always right...

The need for predictions.

http://www.cs.utexas.edu/~kuipers/opinions/electrons-vs-fairies.html

Making good decisions relies upon a mix of luck, and the ability to predict the outcome of those decisions. (preferably more of the later). For knowledge to be helpful, it must improve the ability to make predictions. To determine if that is so, one must have testable predictions made from that knowledge. If the knowledge cannot produce testable predictions, then the usefulness of the knowledge cannot be known.

Virtual Jobs:

Part of the trouble with trying to stop RMT (Real Money Transfer) in games is that the money involved is enough to live on in some places. For instance: the approximate USD (United States Dollar) value of isk I make each month in EVE is near $50. While that's hardly significant where I live, in other places, that's a lot of money. So, then I wondered:

Is it possible to make an MMO designed to provide work and pay for people in poor countries, and actually succeed? It would need to have low minimum system requirements, and somehow obtain, and maintain enough popularity to keep demand for the fruit's of other's labor high. A tall order.
