What we lost is simplicity across the stack.

I learned to program with BASIC. It was awful. I didn’t know how awful it was until many years later. So I don’t miss the language. But something I miss is how easy it was to learn what your machine was doing.

The DOS boot and config involved only two files: CONFIG.SYS and AUTOEXEC.BAT, that was it. Most programs were self-contained, so you could copy the directory to a floppy disk and run them on another machine. If you broke something, copy the files again and restart; that was it… I “broke” config and programs many times, and it was a good way to learn.
