100% agreed on voice control and natural language. Regarding learning the fundamentals of computers vs. dumbing down the system, I fear that no one knows the right answer, and that there may not even be a right answer. There are arguments to made for both approaches and there's no one-size-fits-all sweet spot for that design decision.

I have my own opinions on it but I'm pretty sure I'm wrong too. I think this is one of those things where a bunch of well-intentioned people implement a bunch of different designs over the next few decades, and it just sort of converges on something even though every design leading up to it was fundamentally wrong in some sense, or went to far in one direction.
