I think that part of the idea that we need only 10 % blahblahblah, is that
at some point you might need 100%, while you are developing and making
connections, but once all the circuitry is established and you just cruise
through life, you only need 10% of what is there. Consider the
scientifically established fact that the majority of your connections and
even neurons disappear between fetal stage and teenage years.
