Earlier quoted context omitted.
There isn’t a need to read anything beyond introductory materials to acquire depth, if your competent enough. In fact that’s what I would consider the critical dividing line between a regular genius and a bonafide super-genius. Someone who almost supernaturally acquires expertise/intuition/depth/etc. with very little visible effort.
What does being competent enough mean? Do you have an example of bonafide super-genius?
He once mentored a guy who was so ridiculously good at writing programs, that he wrote out (once) a 5 foot stack of punch cards (back when that was how you would code), to create a program that was needed by the company for some purpose.
It worked, flawlessly, the FIRST time.
This was his MO.
Once, he wrote a program for an internal client, and it got shipped. They ran the program and ran into a problem. My friend told him to debug it for them… he replied “I don’t know how”. Up to that point in his life, He had never had to debug a single piece of software…
My friend helped him debug the program: Turns out, the problem was not an issue with his code, the customer had given him the wrong spec for a critical interface… and that was the only reason it had not worked the first time.
There are truly people that qualify. The only note I will make is that generally if you are a super genius in one dimension, you likely have something you are absolutely terrible at in another. Hopefully it is in a dimension that either doesn’t matter, or you have enough complementary people around you to mitigate it.
