The “in principle” limitation will turn out to be significant only if quantum effects matter in the brain. This is a hotly debated topic [NEED REFERENCE]. Quantum effects do not change what can be computed per se, because even a Turing machine can simulate a quantum effect, but it would take an impractically long time to do so, potentially millions of years or more [10]. If quantum effects were to matter in the brain then we would need to wait for further progress in quantum computing to simulate a brain. Personally, I believe that quantum effects are unlikely to matter and that we will be able to simulate an entire human brain in a digital computer with sufficient detail. We can't do it quite yet, as our present digital hardware is too slow and has insufficient memory (we also do not yet have a complete map of a human brain).
