I mean, maybe if your code was simple enough that you could keep the entire state in your head at once, but we're talking about guys writing memory management routines and OS kernels. In C. With no LSP, no syntax highlighting, no linting, etc.

It's one thing to say "my hardware is too limited, I can't fit all that extra context into memory", but to be working with that tech stack and to say "I actively choose not to see the context around the line of code I am editing at this instant in time" is just obtuse, no matter how many programming languages you've invented.
