I do have to react to this particular wording.
RNA polymerase literally slides along a tape (DNA strand), reads symbols, and produces output based on what it reads. You've got start codons, stop codons, state-dependent behavior, error correction.
That's pretty much the physical implementation of a Turing machine in wetware, right there.
And then you've got Ribosomes reading RNA as a tape. That's another time where Turing seems to have been very prescient.
And we haven't even gotten into what the proteins then get up to after that yet, let alone neurons.
So calling 'computational interpretation' bunk while there's literal Turing machines running in every cell might be overstating your case slightly.
