I worked with an engineer who was partially sighted and could only see a tiny fraction of the screen at a time, he had essentially memorized most of the code base. What struck me was that when I started working, while not the same, that was how you got anything done, API docs were on paper, we had stacks of books on our desks, code navigation tools were laughable, no intellisence, and screen were small (14" 640x480). When I was regularly writing win16/32 code I would rarely need to look anything up, the cost of doing so naturally trains you to remember. I don't miss it tbh
