You are totally right. Going even way back, in days of TurboPascal, you could include graphics.h and get a very cool snake game going within half an hour. Today, doing anything like that is a week of advanced stuff. Someone wanted to recreated that experience today and came up with this: https://github.com/dascandy/pixel

But as you can see how much boiler plate was needed to be written for them to write this.

See the user example and then look at src for boilder plate.

In old days, you could easily write a full operating system from scratch on 8051 while use PS/2 peripherals. Today, all peripherals are USB and USB 2.0 standard is 500 pages long.

I also agree that we have left behind the idea of teaching probably or at least removed it from the mainstream.
