"Race for the Prize" by the Flaming Lips

What is the Theme of this Song?
To me, this song is about overambition. How we are always aiming for perfection that will probably never be achieved.
The scientists in the song want to discover the cure, save the world, become superheroes. They'll do anything to achieve their goals. But no matter how far they try to climb, after all "they're just humans, with wives and children."
