Not OP but aphant: the information is there, we just can't "see" it. So we can know how to navigate because the map is stored, it's just that we can't access it

Not OP but aphant: the information is there, we just can't "see" it. So we can know how to navigate because the map is stored, it's just that we can't access it in a visual way. Note that for me the access is less detailed and also fades quicker. As for maths: I actually have a physics PhD and am now a C++ dev. I couldn't mentally integrate anything complex. Never needed to, someone invented paper at some point ;) I'm a decent programmer I'd say, it seems to be common among aphants to be good at abstract reasoning, which I think really helps with coming up with good programming solutions to concrete problems.
