Fortunately I completely disagree.

“Imagine going back to the year 1600. Even then, Western Europe was one of the more educated parts of the planet, but back then about 20% of the population could read and write. And I suspect if you went back there and you asked someone who was capable of reading and writing—say a member of the clergy—and you said: “What percentage of the population is even capable of it?” They might have said: “If you have an incredible education system, maybe 50%.” You fast-forward 400 years to today, and we know that that prediction would have been wildly pessimistic; that nearly 100% of the population can be literate. But what similar blinders we have on today? If I were to ask you: “What percentage of the population is capable of understanding quantum physics? Or what percentage of the population is capable of contributing to medical research?” You might say maybe 5 or 10%, or with a really good education system maybe 15 or 20%. But what if the answer is a 100%? What could that mean for the rate at which human society could progress? What would that mean for the human condition? But that is just one aspect of the types of blinders we have on today, that in 400 years will hopefully seem silly.” —Salman Khan, Harvard Class Day 2014
