Computers today are powered by artificial intelligence technologies, allowing them to engage in conversations, compose songs, paint paintings, play chess and go, and diagnose diseases. The power of a computer is determined by its hardware speed, which is limited by the laws of physics, and the efficiency of the algorithms it runs, which are written by humans. Despite the physical limits of computers, there are still computational hurdles due to the limits of algorithms, such as problems that are impossible for computers to solve and problems that are theoretically solvable but take too long to compute.
