Facts about my inventions: Human level artificial intelligence can build a house in 1 year. Super Ai can build the house in 20 minutes. The question I was trying to answer in late 2007 was: is it possible to design a robot that can build the house in 1 second? It took me a week to come up with the answer. In order to do this (build a house in 1 second), the robot has to have the ability to control atoms – to merge atoms together to form the house from a remote distance. This is the real function of my practical time machine – it was designed to surpass Super AI. All three inventions: Human Level AI (2006), Super AI (2007) and the practical time machine (2008) are built on top of each other recursively.
