One of the interesting pieces of science that I think a lot of people don't think about is strategic investment. At one point I was paid from a government grant to do high power laser research. Of course there were goals for the grant, but the grant was specifically funded so that the US didn't lose the knowledge of HOW to build lasers. The optics field for example is small, and there are not that many professors. It is an old field, most of the real research is in the private industry. However what happens if a company goes out of business? If we don't have public institutions with the knowledge to train new generations then information can and will be lost.
