This seems a bit contradictory. You say that the lone genius is often overestimated, then you attribute Kuhnian paradigm shifts to these lone geniuses. Perhaps it is better to be skeptical about the idea of paradigm shifts. They are often portrayed as some kind of phase transition, but they are usually (or always?) foreshadowed by a generation of debate, and when history books look back, they only present a retrospective consensus on that imagined consensus which never actually existed in the debates of the day.
