I don't see why this idea is so hard to grasp. With the current state of programming languages, definitely not. But I believe much more intuitive forms of programming languages will eventually be made such that your average intelligent user can accomplish non-trivial computation.

Programming languages are the computer analog to natural languages. The real problem is that most of our brains aren't wired for programming languages. If we can bridge that gap, that will completely revolutionize the way people interact with computers.
