I find it interesting that humanity looks at what science have managed to deduct so far and yet feels it will take hundreds of years to gain asnwers to some of our most elusive questions such as Dark Energy and Dark matter. We can clearly see how we have speeded up the findings along our history and even in our own lifetime the answers have rained down on us. I am 41 years old and I am excited like a small kid with a present infront of him, about the next 5 to 20 years, nmot to mention next 40 years.

Just spend time with senior citizens above 70 and closer to 100, and your perspective will shift drastically when it comes to how far humanity have reached in its quest for discovery and understanding.
