All computers are is a series of code telling what to happen when. 1 or 0 telling different aspects of the system that it either should or shouldn't be doing something. Why does it have a processing speed limit? It takes cutting edge computers today like 30 years to find the next prime number (yes there's a computer running right know whose only job is to find an even bigger number that is not evenly divisible by any number other than itself and 1). If they can calculate the speed of light, why not work at the speed of light as well? (something)'s law (i believe it starts with an M) states that computer technology will exponentially increase computing power up until 2020 or so. We're making these things and basically telling them what they can and cannot doso how's there a limit to how fast it can process info or calculate things?
