Me neither. Digital Mechanism makes one observable at least ranging on the continuum, but it is possible that it concerns only the frequency operator. There is a continuum of computational extensions, as the universal dovetailer dovetails also on the input, including the elements of any possible field like R, C, H or O. (H = the quaternion, O = the octonion). My body is locally a machine entails that we are confronted to many non mechanical entities, just by the first person indeterminacy. But now, many of them can be equivalent with respect to the prediction, so “counting” the worlds is beyond the mathematics available today, and it is not clear if such counting makes sense. I got recent clues that the high cardinals might play a role in the origin of space, which is a “quantum” (in the arithmetical sense) phenomenon.
