Q: Since the real-world does all kinds of crazy calculations in no time, can we use physics to calculate stuff?

The original question was: I’ve heard somewhere that they’re also trying to build computers using molecules, like DNA. Since the real-world does all kinds of crazy calculations in no time. In the earlier epoch of computer science there was a strong case for analog computers over digital computers. Any physical phenomena that represents information in definite, discrete states is doing the same thing a digital computer does, it’s just a question of speed. Today we’re seeing the advent of a new type of computer, the quantum computer, which is kinda-digital/kinda-analog.
