I do agree, my point is rather that the question "“can computation be sentient” is trivially answered as, no it cannot. Is a computed brain sentient is like asking, 'is a computed sun hot?'. Computation is a subjective interpretation of a physical process. You don't get wet from a machine that computes the weather.

A digital machine and an analog one aren't equivalent merely because their behaviour can both be explained in the same terms. (i.e. computationally). That's not to say by the way you can't make some kind of sentient digital system, just that computation isn't really relevant to answer that question.
