I maintain that the genetic code is digital, its interpretation and execution
are too. When a ribosome in a cell finds 3 cytosine bases in a row in
messenger RNA that means "place a proline molecule as the next amino acid in
the linear sequence of the protein you're building". That's exactly what it
means, that's all it means, and that's precisely what it does.

But that's a good thing if the analog-digital distinction is bogus. It is.

Sounds nice, but I can't think of even one example where it's true.

No, it still has meaning, it means that it's pointless to make distinctions
where none exist and if you understand computation then you understand
everything, including God's source code.
