To be honest, I really like the idea but I dislike that it is based on a microcontroller faking the components.
It reminds me of a similar experience I had in a museum where the experiment had you cycling to give power to a bulb. The quicker you cycled, the more power you gave to the bulb and the brighter it was. But it was based on some microcontroller and the light bulb’s brightness was not proportional to how fast you cycled. It has like 3 preprogrammed brightness. It completely failed to give kids the intuition of the physics behind the phenomenon.
Anyway, it’s probably an unfair comparison but I like having the real deal when learning or teaching.

One of the biggest “disappointments” my professors shared - which I’ve never confirmed in industry- is that this is super common for digital logic, or else it’s just a “lookup table” with precomputed outputs for every input.
