I'd say that's true today, but it's not a luxury Margaret Hamilton had when she wrote the code for the Apollo lunar lander. Since things have changed quite a bit since the 1960s, I wonder how much code we software people will be reading 50 years from now.
Very few of us read code today. Almost all of us read a human-readable description of what the software must do, and that is compiled into the actual code :-)
But seriously, the compiler/interpreter is the ultimate expression of Hal Abelson's dictum.
