“[sic] Imagine a tool was invented to help a researcher to improve by just 1%. The gain would hardly be noticeable in a single individual. But if the 10 million scientists in the world all benefited from the tool the inventor would increase the rate of scientific progress by roughly the same amount as adding 100,000 new scientists. Each year the invention would amount to an indirect contribution equal to 100,000 times what the average scientist contributes.”
