Milner on Invention
When I was a PhD student, I attended a talk by the late Robin Milner where he said two things that have stuck with me. The first, I repeat quite often. He argued that credit for an invention did not belong to the first person to invent something but to the first person to explain it well enough that no one needed to invent it again. His first historical example was Leibniz publishing calculus and then Newton claiming he invented it first: it didn’t matter if he did or not, he failed to explain it to anyone and so the fact that Leibniz needed to independently invent it was Newton’s failure.
