         | I suggest reading up about how we found the cure for scurvy and
         | then lost it. The problem wasn't that someone forgot to record
         | "the cure for scurvy is vitamin C" the problem is that people
         | were wrong with what they "knew" cured the disease.
         | 
         | Basically: the act of preserving and carrying on the wrong bits
         | of knowledge lead to a regression with deadly consequences.
         | 
         | The social side of things can't be ignored either. Rulers,
         | religions, and pop culture can and does choose to selectively
         | remember history. In recent years people even take delight in
         | being uninformed about various topics.
         | 
         | So it seems like there's a sort of knowledge decay working
         | against general progress. The question is: will progress always
         | (on average) increase faster than that decay or will we reach
         | some kind of equilibrium or perhaps even regress (idiocracy,
         | for example)?

         | Nope. You can pass on myths the same way. All that happens is
         | that you get more refined myths, that always have "evidence"
         | for them at any point in time because they are refined by each
         | generation to fit any new observations.
         | 
         | It's worse with oral knowledge[1]: oral "knowledge" that is
         | passed down is frequently more damaging than not passing
         | anything down at all, because in the lack of any knowledge on
         | the subject, people will try to gain some knowledge (whether
         | experimentally or not), but with "knowledge" passed down, there
         | will exist pockets of people who will actively resist any
         | attempt to discard that "knowledge".[2]

             | I doubt it - which one is the "correct" message is going to
             | be up to chance, not up to a network effect.
             | 
             | Even if you take the optimistic approach and only retain
             | that knowledge that is common to all branches, there is a
             | vanishingly small chance that the _correct_ knowledge would
             | be retained, because the errors in transmission are not
             | going to be completely random - the sort of error one oral

             | introduced by other storytellers.[1]
             | 
             | It's why the history of tribes who did not write things
             | down is treated as myths: the myth-makers are likely to
             | weave whatever current affairs into existing mythology to
             | "explain" new observations, in the process discarding what
             | was there in the first place.
             | 
             | When the record is written down, at least we can read what
             | was thought at the time of writing.

             | error after gen-20 -> Longer than a man. Probable error
             | after gen-30 -> Taller than a man. Probable error after

               | Quantum randomness and the huge number of variables at
               | play point to the fact that believing that we don't have
               | free-will is a _non-falsifiable notion_.
               | 
               | Consider this thought experiment: God comes to you and
               | says ... "Here are 2 universes you can observe, one in
               | which people have free-will, and another, that looks
               | similar, but its people are just sophisticated
               | automatons. Make an experiment to say which is which."
               | 
               | Your irrefutable argument quickly falls apart because
               | there's no way you can show any relevant evidence for it.
               | And it's worse than talking about the absence of God,
               | because we experience free-will everyday. It's like
               | talking of consciousness -- we can't define it yet, but
               | we know it's real, as we're thinking and talking about
               | it. And a theory being _non-falsifiable_ does not make it
               | false. God could exist and you could have a soul.
               | 
               | You may or may not believe in free-will. But not
               | believing in free-will is dangerous because it makes one
               | believe that everything is predestined, so there's no
