I'm a gollege student in Finland and currently trying to build two things:
1. Robotic hand that works using AI. Designed for people who have lost their hand. The AI monitors your electrical nerve signals and tries to guess which finger you wanted to move. Sure, it's a guessing game, but the probability of the AI getting it right is about 99.99% so does it really matter?
2. Time machine or reverse entropy machine using AI. I'm building a device that monitors particle absorptions and emissions on an atomic level. If it detects an atom absorbing a quantum packet of energy of size x, it will make the atom spit out a packet of energy of the same size. Once again I'm using a trained AI to detect these events and guess what to do next. I've already succeeded in rebuilding a small piece of graphite using this method. Basically, in the future my machine can rebuild your worn out shoes to be brand new again. I call it time machine because from your shoe's perspective it travelled back in tyme.
