At the end of season one Major with the laughing man about how humans remain individuality through "simple every-day curiosity". I must admit that I'm too stupid to understand both of those, so could someone in short explain to me what she meant?
shareShe was referring to what made the Tachikoma go from being collective copies of one another to being individuals.
shareShe was talking about the previous episode, and how the Tachikoma's showed just how far they'd come and that they'd developed very strong, individual personalities, and all through curiosity. It served as a direct parallel and opposite version of the Stand Alone Complex that the Laughing Man phenomenon had caused, with so many people exposed to the same stimuli and information that they began doing the same thing, performing Laughing Man-esque terrorist acts that looked as if they were done by one person.
Meanwhile, these adorable, completely new machines shared the same information among themselves, but through the sheer scope of their curiosity, they developed their own individual personalities, having to push in different directions to satisfy those curiosities, one of them having even taken to reading print books in a previous episode. The fruits of that curiosity kind of revealed themselves in episode 25, when they completely overrode what they were designated to do in favor of tracking down Batou and saving his life, because at that point they were individuals, even capable of self-sacrifice, and all because of that every day curiosity. To the Major, that was indicative of hope that people could still be individuals even in an increasingly cyberized world.
