That's exactly it. Going to space or Mars, were impossible dreams for hundreds or thousands of years, now we have robots and satellites over there. If we don't dream about going to the core, we will never get there. Big challenges make us dream big and work hard to accomplish them. Also, despite now seeming so hard, I bet there's tons of low hanging fruit discoveries just waiting to happen. Have you seen a diagram of the inside of Earth? It's just laughable, especially if you compare that to the level of detail that we have of Earth's surface, or even the Martian surface.
