Some people can't see mental images

I’ve read tons of these and still have no idea if I have aphantasia or not. I can’t understand whether people just have different ways of describing what’s in their minds eye or if there’s really a fundamental difference.

Relatedly, I'm not sure I really believe people who say they think in code and can't be bothered to render their ideas in design or decision documents with actual reasoning. I can't even tell if something is a real thought I'm having /in my own head/ until I've written it down or otherwise recorded it somewhere in the consensus reality. Very often, I /think/ I've got some problem or idea all fleshed out in my mind, but the process of writing it down (in code or prose) reveals that this was all just a kind of illusion. Or maybe I really did have it all figured out but something got lost in the process of writing it down? Seems literally impossible to say.

But IMO it would be weird if all of us meat machines of the same species had radically different methods of cognition, since the empirical evidence suggests that our behavior, in the broadest possible sense, is not radically different, and neither is our thinking hardware.

Code is "written it down or otherwise recorded it somewhere in the consensus reality"

"thinking in code" means "render their ideas in code", like you render your ideas in English.
