That can be shown to be inconsistent, unless some precautions are taken, but then we will miss some mathematical structures. > We need a way to think about these "infinities". Are they meaningful?

Mechanism do answer this: all computations exists (indeed, in all models of arithmetic), and that generate an internal phenomenology which cannot be bound in any mathematical way. We can say that it is beyond the supercargo infinities studied today, and there are some recent evidences that we might need the cardinal of Laver, which are very close to the "Kunen bound", above which cardinals can no more be extended (at least if we keep the axiom of choice) without leading to inconsistency.
