Rather than "fragile digital" it may be more apropos to say "efficient analog". If anything, analog is more fragile -- affected by changes in temperature, drive voltage, chemical gradients across individual chips. Digital is an escape from that fragility, but at the expense of power efficiency and speed.
- tlarkworthy 12y agoI think of digital as a logical house of cards. A single flip of a bit has a cascade of effects. Analogue is affected by lots of things, but good analogue design is robust to these perturbations. Digital circuits can't be perturbed outside their tolerances. Digital design can't generally deal with a noisy AND. It this kind of manufacturing noise they want to deal with with neuromorphic chips. As I said, I am sceptical myself but that's the justification I have heard from this research domain.
