I was browsing around the National Geographic
megastructures web site and I saw the episode about a hi-tech prison, NBCI - Maryland.
I searched around a bit and this is what I found.

I cannot help but wonder how come that in the 21st century we, humans of every nation, most intelligent form of life, are still building steel and concrete cages instead of schools and hospitals, why we keep trying to fix the effects rather then the causes. It's incredible that we just don't seem to learn, we appear socially stuck into the 12th century and unable to change way of doing things. What are we going to the Moon for if we are not even able to manage ourselves? We create poverty and then say that we want to eradicate it. We have brilliant technology and science but we still use it to make weapons. We destroy the environment that we need to exist and then say that we want to preserve it. The dichotomy is obvious but the solutions don't appear to be up to the problems. We only try to deal with the effects of our actions instead of act responsibly in the first place. If it wasn't dramatic it would be ridiculous.
