Humans are a bit obsessed with learning about new things, which isn’t really a bad thing. If it wasn’t for our wish to learn all we can about the world, we would not have progressed as much as we have since the Stone Age. From farming to hunting, everything that we had to do for our survival was used to be quite difficult in the past. But being our stubborn self, we wanted to perfect everything for us and our future generations. We kept working on improvements in every walk of life and eventually made things a lot better for ourselves. However, we never stopped learning about things.
When we got satisfied with learning about the earth, we turned to the stars. But like all other things associated with out species, we have a unique way of learning. Only a couple of hundreds of us were born with photographic memory, the rest of us had to devise techniques for memorizing stuff so we can keep on progressing in the world. Sure, there is internet today that can help us with any information we need. But looking things up on the internet is not a talent, using our own ability to memorize information and use it for the good of society is what matters.
