I'll just add one thought. I do support what my colleagues have said on the tremendous benefit of focused funding that sometimes produces magical results, but I'm also a true supporter of not directing so much, of letting it emerge. That's where we do get some magic as well. It has a balance between those two.
Certainly in health research there are examples where government has set policy directives, identified areas where we want research, and put funding in there, and it has produced tremendously. But it is sometimes the random research that can really lead us as a nation and produce innovative things.
