A "spec" for a human brain would have to include beliefs about questions of value, like "what is the point of human life?" Such a spec couldn't in principle be written because there is no objective basis for answers to these questions.
It sounds like you and Taleb hold different values. He thinks that living a life that involves following your own impulses is both valuable and "natural" (a suspect source of objective value IMO). You think that being able to fit into the existing environment is valuable. You might think Taleb is undisciplined and his philosophy could never be widely embraced. He might think you are just mindlessly following the orders of people who don't care about you. At the end of the day, it's up to you how you live.
