I wrote this article this morning pinpointing why I believe an Economically Utopian Society is very possible in the next 40-50 years or so. As the various, up and coming technologies, converge with 3D printing, we will be left with a society that is capable of printing out nearly everything they could ever need, at prices which are close to nothing. Here is the article:

I would love to hear your opinions on this. I believe we underestimate what the future holds. I also believe in the following of trend lines. If you do this, by 2050-2060, we will have such incredible technologies at such low prices, that I really do thing the world will be a much better, safer, and economically friendly place. Of course a lot can happen by then to take us off this path...
