They can. It's just that this specific program is not capable of translating it.
You wouldn't be able to do any of that without feedack.
* Feedback causes memory-like effects (e.g. reverb and oscillation whine in audio systems).
* Besides maybe memresistors, memory is pretty much always implemented via positive feedback (i.e. >unity loop gain) plus some sort of saturation to prevent exponential growth (which you typically get for free in physical systems if you can keep them from exploding).
Furthermore, digital behavior is an emergent effect from analog physical systems that are designed to be bistable. Digital systems will always make use of analog physical processes "under the hood".
