The other issue is that too many programmers these days don't have a solid computer science background... I'm all for people being self-taught and learning programming on their own... But the downside of that prevents individuals from learning how things work at a lower level.

I've never written a line of Obj-C or Swift in my life, but all you have to tell me is "struct = value based, class = referenced based" and I immediately know how it works...
