Universidad Simón Bolívar Professor Blai Bonet joins us and discusses the issue at hand as he sees it, "In computer science and AI in particular, all the problems that we try to solve, almost all of them, they are intractable. Intractability means that you need an exponential amount of resources. It could be time, it could be space. And by space I mean memory, computer memory. Time is easier to trade off. It's easy to handle time than memory. Memory is expansive and maybe you don't have enough memory. Time otherwise, you can put your problem to run and then you go on vacation. Hopefully, by the end of the vacation, the problem will have ended."
