Why study theory of computation?

What exactly are computers? What are the limits of computing and all its exciting discoveries? Are there problems in the world that computers can never, EVER solve? Theory of computation is the fascinating theoretical study of computer science that explores the limitations of computing—which, of course, anyone can learn. :)
