"More recently, DARPA [creator of the Internet] has shifted its focus from delivering better tools for soldiers to changing the soldiers themselves with biotechnology, making them more powerful with a new metabolism. They are working on vaccines against pain. They are working on drugs that allow soldiers to go on for seven days without sleep and drugs that allow soldiers to go without food, living off their own body fat. The same 'enhanced' human will be relevant within sports, eldery people and others."
Interesting high-level overview of our past four centuries and this century from Global Business Network. More in this link for the complete PDF document. This document ranges from religion, enlightenment, science, GNR technologies, ethics, changing economical powers to politics. Interesting comments on the rise of China and India as economic superpowers this century and their focus on open source en open technologies and how they relate to Africa and South America as growth markets. I totally agree. Marc Faber (one of my favorite authors) also has a very interesting view on the decline of the US as an economic superpower this century. See his landmark book called Tomorrow's Gold in which he clearly exposes the rise and demise of all key hegemonies since the Roman Empire (Spanish, Dutch, Britain etc.) and analyses the fall of the US power. Concerning the biotechnology issues as quoted above I recommend the book from Fukuyama called Our Posthuman Future: Consequences of the Biotech Revolution. And this also resonates with the concerns raised by Bill Joy (The Future Doesn't Need Us).
