Rob, it might be an idea if you stopped going on about topics which you clearly haven't got a very solid grasp of. Clearly thermodynamics is one of those.
Intelligence is not what is "keeping entropy at bay". The available energy of the sun is what is doing it.
We are, of course, slowly losing if you take a very big view.
As for why we want to learn anything: It is just as Doddy said "knowledge is good". I find it just feels good to learn things. It's better than a cold beer.
