Abstracting away all of the details underlying the tech is a double edged sword. On one side, you get massively higher adoption due to a lower barrier to entry. On the other, you now have a massive population of folks who don’t understand the the “fundamentals”.

I’m not sure we “need” to improve the general understanding. I mean how many ppl know how to change their own car tires or oil? If anything you just keep creating niches for ppl to make livings in.
