On one level I agree with you however I think that the barn door is open and the horses are heading for the treeline.

I trained as an industrial electrician before becoming a professional programmer (I programmed long before either) so I have an incredibly healthy respect for electricity and machinery.

That said I also think the benefits of putting hardware and software into the hands of talented new users is well worth the (potential) downsides, I broke many many things to learn how to not break things, that is how you progress in the early days.
