Navier-Stokes is only incidentally related to real life. It's pure math.

Right, smooth vector fields aren’t actually physically realizable.

Navier Stokes is probably Turing Complete.

Probably, yes. But the gymnastics required to make it Turing complete are unlikely to be in the regime that describes real fluids.

In the sixties some people experimented with fluidic logic gates.

Those probably relied on friction?
