I'm confused. In previous conversations you have claimed not to
known what "exists" means.

If computation are simply integers, they all have the same measure.

If there is some more complex relation, the existence of computations
is not guaranteed by the existence of integers. Any computer
progamme can be represented as a sting of 1's and 0's, but only
int the context of some particular computer.
