    I now believe the Ratatouille movie is based on a true story.

    The sad part is, it took rats to teach you this. Unfortunately, way to many Dr.’s and scientists are only book smart, and most are not very.
    Very few are actually common sense and emotionally intelligent.
    Probably why more Dr.’s and scientists have worked on, and invented, some of the most poisonous, destructive things which harm every single thing on Earth.
    And, if this TRUTH!ful comment upsets you, you are part of this destructive issue which perpetuates the lies your overlord, slave masters feed you constantly.
    That is as kind as I can put this TRUTH!

    We need better people to help run civilization.

    It never ceases to amaze me that human arrogance underestimates the intelligence and emotional sentience of species other than our own. Did it ever occur to this researcher that the Rat was Training the Humans………

    Oh no.
    While we’re worrying about AI takeover..
    This is another takeover threat nobody is talking about.
    They’re even out to steal joy from us

    The rat infestation doesn’t have to drive you crazy. Sometimes the rat infestation can just drive crazy.
