Right. However, the inventions you mention, were not expected to be useful the same year. The problem today is not that there is a demand to focus work on potentially useful areas; that's fine as far as it goes. The problem is that there is too much demand that work bear fruit in the short term, whereas in fact we have picked most of the fruit from the branches currently in reach, to mix metaphors, and we need to go back and do some more long-term investment.
