I’m an artist - I draw professionally and studied drawing in a group setting. It seems like a profession that would require the highest level of visual imagination. And I wish I could see clear pictures in my head, but I don’t. I need to have a reference in front of me, constantly compare it with my sketch, and refine it using knowledge and techniques that took years to learn.
When discussing this concept with my artist peers, many say they’re at 1. But they clearly aren’t - I can see that in their work process. There’s an immediate difference in art quality depending on whether the artist is drawing from reference or not. If someone could truly see the picture in their head and draw from it, they could skip years of art training and become good almost immediately. Such a genius would be clearly obvious to their peers. But I haven’t met a single person like that - it seems like everyone works with roughly the same hardware as I do and has to develop the same workarounds to become good.
I believe that Kim Jung Gi was a 1. I’m sure there were other historic geniuses with such a superhuman ability. But I’m also sure that 99% of people just aren’t there - whether they admit it or not.
