The idea that there is such a thing as analogue computation is a classic oxymoron. The logic of the digital is computation and vice versa. (Now let's see how quickly this thread devolves.)

eli added,
whitequark @whitequarkalso some of the things people normally think of as digital components, like DRAM, EEPROM, or Flash memory, only really have a digital(-ish) interface whereas the guts are completely analog. violate EEPROM write timings, heat it up a little & some 0s will swap with 1sShow this thread1 reply 0 retweets 0 likes -

Yes, all computers are ultimately physical systems. But we can't say that by virtue of them all being physical systems, all physical systems are computer. They should exhibit and operate within rule-bound systems or else the thesis devolves into an unholy pancomputationalism.

Yeah, she points out that many people think of digital circuits as 99% digital with occasional “analog leakage,” but they’re more analog than you’d think, and to your point are united by digital /interfaces/

You see there two different issues here: can the leakage be explained within computational theory. Majority of this cases are due to concurrency constraints set by the traditional Turing machine, they are not essentially counter examples against the digital paradigm.
