You misunderstand my definition of fundamentals. I'm talking things like filesystems, networking, protocols, hardware, etc. You can spend an eternity learning all the different Apps on Android or iOS.

Not once will you figure out how to develop one without access to a traditional Desktop system, and an understanding of the fundamental underpinnings thereof. That's changing a bit now with some efforts in the FLOSS space, but it is roughly true today.

While there may be more developers now, I do not see a significant decrease in overall tech illiteracy.
