If at the fastest speed a computer can physically operate the program would take longer than the expected duration of the universe, I believe we can safely say it does not usefully represent the information, even though in mathematical relationship it may seem to. Less absurdly, if the program takes longer to run than the MTBF of the computer it operates on, we can say the same thing with some probability. It’s a roundabout way of saying that what seems to work in math isn’t always possible useful or functional in material reality. Since Kolmogorov seems to be pointing in this direction of blurring computation in material reality with mathematical information it seems worth considering.
