Time to market
Dr Anderson: "advances made by scientists might take twenty years before appearing in the market".
Consider the transistor, invented in 1948. It did not show its full importance until the late 1960s when integrated circuits became available. But the quantum mechanics that underlies the transistor was developed in the 1920s.
So that was a gap of some forty years between scientific research and major pay-off. The moral is that a short term approach to science funding will not spend money wisely.
