The reason for this is, among other things, systems programmers wrote the UIs in 1983. Today random twenty-years-old web-muppets write the UIs.

The system programmers of 1983 were used to low-level programming, and most of them had probably written code in assembler. Web programmers seldom have that deep understanding of the computer.

At least, this is true from my own personal experience.
