Not so, it is analog. There is no evidence to the contrary, only
conjecture.

No. Nature does not truncate it we do.

At extreamly low levels.

This is very true, digital always has quantization error, has high initial
costs, and complex.
You have a problem in scale, on one hand you talk about things that are
10E-20 or smaller.
On the other you talk about things far bigger things.

You have the wrong group, you need "analog/digital communications EEs" or
something like that
