A fantastic house of cards

From Where are the Geniuses of Today? by Alex Petrov:
The ability to reason, to compute, to manipulate the symbols and rules of logic -- this unnatural talent, too, must lie at the very margin, where small differences in raw talent have enormous consequences, where a merely good physicist must stand in awe of Dyson and where Dyson, in turn, stands in awe of Feynman. Merely to divide 158 by 192 presses most human minds to the limit of exertion. To master -- as modern particle physicists must -- the machinery of group theory and current algebra, of perturbative expansions and non-Abelian gauge theories, of spin statistics and Yang-Mills, is to sustain in one's mind a fantastic house of cards, at once steely and delicate. To manipulate that framework, and to innovate within it, requires a mental power that nature did not demand of scientists of past centuries. More physicists than ever rise to meet this cerebral challenge.
