the greatness of humanity‏

'smart is he who learns from his mistakes.
wise is he who learns from others' mistakes'.
when Gutemberg brought his idea of the printing press, people who knew something began to publish manuals about how to do or make something. and this was a giant step for learning faster, and humanity became more and more knowledgeable. our learning keeps growing exponentially. we learn way faster by watching others doing something-or reading about it, so we don't have to make the same mistakes that they did. humanity, like the most advanced species, learns from others. that's why we gather. wolves, elephants, lions, baboons, dingos, live in close proximity-and learn from each other. our advantage is that we are able to communicate better-the language-so we are able to tell with more detail and faster, whatever we want. then we learned to read and write-then, as i said, the press. now the internet. we exchange ideas. whatever we know, we let others know. so the others don't have to make the same mistakes we did. we invest time and money trying to learn something, and then we talk about our findings, so the others don't have to go through the same to learn that. of course, sometimes we want to try something that others couldn't make it work, and we are willing to try a different way. then, sometimes it does not work. but we have the knowledge of the way it does work, so we can go back to it. and now with the rcgroups, here we are, having fun and living like wizzards, just pressing a few keys and talking to everybody, wherever he is, and getting back his input in no time, to enjoy more and more this magnificent hobby of ours.
