Read this article. If it’s true, the world will be a very interesting place by 2025. It also underscores the maxim: with the ability to do great good comes the ability to do great harm.
Even a primitive diamond-building nanofactory can create products vastly more powerful than today’s versions. Electrical power can be converted to motion, and vice-versa, with one-tenth the power loss and about 108 (100,000,000) times more compactly. Computers can be a billion times smaller and use a million times less power. Materials can be about 100 times stronger than steel.
Molecular nanotechnology will be a significant breakthrough, comparable perhaps to the Industrial Revolution—but compressed into a few years. This has the potential to disrupt many aspects of society and politics. The power of the technology may cause two competing nations to enter a disruptive and unstable arms race. Weapons and surveillance devices could be made small, cheap, powerful, and very numerous.
