Reads like science fiction becoming reality. In particular, the science fiction series by Hannu Rajaniemi (Quantum Thief, Fractal Prince, Causal Angel) has 'natural computational substrates' as one of its themes.
This all seems to exist on the borderland between discrete and continuous mathematics, which is a pretty fascinating topic. Digital systems rely on discrete mathematics, while things like fluid dynamics are much more in the world of continuous smooth functions. It seems as if they're really building an interface between the two concepts.

- dane-pgp 4y agoI'm reminded of the Church–Turing–Deutsch principle[0] which states that a universal computing device can simulate every physical process. Putting that another way, I think it means that anything that can happen in the universe can be modelled by sets of equations (which we might not have yet) which can be calculated on a universal Turing machine. There is the question of what can quantum computers do polynomially or exponentially faster than a classical computer, but I think it's accepted that all quantum computations can be achieved classically if you don't mind waiting.
