 CHAR: At the end of the second part, Meltdown, this quote is given:  "The danger of the past was that men became slaves. The danger of  the future is that man may become robots." The film credits it to  Thoreau, which is impossible, as the word "robot" did not enter the  English language until more than sixty years after Thoreaus death.  This quote is actually from Erich Fromm.
