Not the one in question, though, since Omega can be approximated—and typically is, even if only as a (50+x)% correct predictor. Humans are an approximation of Omega, in some sense. Solving a problem assuming a hypothetical Omega is not unlike assuming cows are spheres in a vacuum, i.e. a solution of the idealized thought experiment can still be relevant.
