Ramanujan was an anomaly. What do we learn from someone like him? Can we reproduce it? Should we aspire to reproduce it? Or will it cause more harm than not?
Some people are born with an innate gift for math (or music, or whatever else). And the location and circumstances these people are born into are not correlated to anything. As far as we can tell, they are as likely to be born in a slum in India as they are in Cambridge (UK or Massachusetts, take your pick).
Therefore, we should strive to make opportunities available to everyone as much as possible so anyone, anywhere, born with such gifts can make the fullest use of them possible (should they choose to).
I’m all for meritocracy, but we should strive so that most people can succeed in parallel to a good family life. So that the children are balanced and loved, and we have a second generation who’s even better.
