Yeah. Fairly obvious applications in teaching/education devices. Though I think it should be noted that a lot of what schools want to teach with devices like this is precisely the pin connections and circuits this thing elides.

But I am not sure about the rest.

And what you don't see in demos like this are the practical limitations that the demo avoids. I didn't watch all the way to the end but I had questions about how the device communicates its limitations and handles situations where, for example, it cannot supply enough power.
