For certain choices of "this or that", the ultimate reality is actually unknowable.

With comp we know that the *physical* "bottom" is theresult of the competition among all universal machines, (by UD-7 or 8)and this leads to (re)define physics by such a competition/measure onall computations. The initial base ontology is really irrelevant, andit makes no sense to choose one or another, except for technicalcommodities.

Dear Bruno,

`I am trying hard to be sure that I understand your ideas here.`

`Could you specify the cardinality of "all universal machines"? How many`

`of them possibly exist?`

Put in another way: there is no ontological hardware. The hardware andwetware are emergent on the digital basic ontology (which can bedescribed by numbers or combinators as they describe the samecomputations and the same object: you can prove the existence ofcombinators in arithmetic, and you can prove the existence of numbersfrom the combinator S and K. So the basic ontology is really the sameand we can "know" it (betting on comp). It is really like the choiceof a base in a linear space.

`So is there or is there not something that corresponds to`

`"resources" (such as memory) for the Universal machines in your thought?`
