Are you talking about meditation?
I still can't see how "matter" is the result of a sum on an infinity of
interfering computations".
Common people can touch and feel the matter (this physical universe). They
don't need this strange process to see it.
Your explanation is rather strange.
As said before, I don't think substitution level exists. So Comp. and UDA
won't work here.

I think many good physicist won't agree with you.

Please provide more explanation.
