Physics may bring faster solutions for tough computational problems. Researchers have used an elegant method based on statistical mechanics -- called the vertex model -- to create more efficient algorithms to solve complex problems more quickly. The research could solve problems in machine learning, circuit optimization and other major computational challenges. Ref. Source 7k.
You have to remember Murphy's law here. "To Err is human, to really foul things up takes a computer" A computer is only as smart as the person who programmed it. I am not afraid of machines becoming self aware for now. I am sure they will fit right in with the rest of us and keep fouling things up.
