That's past 80 characters, and I don't really think this is an interesting place to enforce the rules here — did your instincts tell you that HN readers are about to be bait-and-switched by the editorialized title?
Lots of stuff in biology integrates continuous signals. Discrete counting of discrete events is quite rare.
In many senses you can compute with things that count discretely: Peano Arithmetic is undecidable. Yet unbounded dense linear orders (i.e. the theory of the rationals) are decidable, so you can't embed "program X halts" into them.
