If you held the same logic back towards the beginning of humanity then we'd all still be wandering about the woods poking each other with sticks. Most people don't believe things are possible which is probably some sort of evolutionary thing. A society full of people with their head in the clouds probably wouldn't work so great, but humanity would also stagnate without at least some people looking to the stars.

This could very well be why planned economies seem to struggle with innovation. People being able to devote significant resources to endeavors, that might not make sense to most, is how you get lots of failures, and the occasional revolutionary successes. Do everything by committee and all you get is a shinier version of what you had last year.
