One other thing I've been thinking about. At least among the PhDs I've met, many of them are NOT scientists. That is, they play at science for a while, but it's no great tragedy that they aren't being employed in the academic pursuits. One thing I do wonder is how many scientist-PhDs doing solid work are actually going unfunded, and how many of them are guys and gals researching the CS equivalent of how many angels can stand on the head of a pin.
