It’s easy to advance when you are standing on top of information and technology that others have built up for you the past several millennia.
We don’t have to re-discover bacterial infections so we can now focus on fighting it
We don’t have to re-discover how to invent a circuit board, so now we can focus on optimizing it
We don’t have to re-discover human biology, so now we can focus on treating issues that plagued our ancestors
…And so on and so forth. Just like how our grandchildren won’t have to re-discover the trajectory of other planets, they can focus on how to get there.
Information builds on information the previous generation figured out
