> We as humans use numbers and algorithms (which are really figures of speech, not things), to explain physical reality, not the other way around.

The numbers and algorithms here aren’t what anybody is saying could be sentient. Those numbers and algorithms are representations used to coerce physical objects into doing computation. Processors don’t care about the algorithms you see on your computer screen. So then the questions are “can computation be sentient”, or “are sentient things sentient by way of computation”, and I think that’s much, much harder to answer.
