Mikhail Kalashnikov

People often ask me how I feel about my invention being used to kill people every day and the AK being a common weapon of ethnic conflicts. I want to make it clear that I created my assault rifle to protect my country. You can blame politicians for its spreading out of control on a global scale.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
