My views about this society are that the people were lied to. We can see that they had sameness and they never experienced any emotions. This is good and bad. Good because they were no bad people, no wrong things, such as envy dirty thoughts, etc. But bad because they never experienced love or listened to music. Not only were they shielded from bad things but also from the good, enjoyable things. This society would not be one that I would like to live in because it doesn't matter that we live in a world of pain and bad people, but no one can take away the warmth of love, the happiness of music, and the joy of a newborn child that is your own. There are things that we have to work hard for. Nothing is ever easy.
i think its because if one of the models are broken or wrong they have a back up or just try to get better info then the others or just to get extra data.
