I think it’s easier to conceive of it like this: Each point in spacetime IS storage. Storage can be queried by interacting with it (in a variety of ways), though the process of querying affects the value not only of the querier, but also the queried, which may have side-effects as well. The interaction itself is the computation.

A simple example for the computation: It’s like placing boxes next to each other. Yes I could say 1 box + 3 boxes = 4 boxes, via explicit calculation. I could also simply place 1 box next to three boxes, and without having to explicitly calculate, by nature of the interaction, the result (4 boxes) has been produced

There is no background computation or storage. The universe IS computation and storage. Each spacetime quanta IS storage, and each interaction IS computation.

Spacetime isn't quantized as far as we know. We don't know since we don't have quantum gravity or ability to probe Planck scale. Quantum fields are continuous, it is excitations in the field, particles, that are quantized.

Ah, I thought we didn’t have strong evidence either way. Regardless, I shouldn’t have stated spacetime quanta so matter-of-factly. I just have an easier time conceptualizing if I treat everything like hypervoxels and that leaked in.

The answer is we don’t know for certain

There are even some philosophers/mathematicians who attest to finitism (they’re not mainstream, though), but if correct would undermine our idea of fields and continuous structures more broadly
