180: Subjective experiences, Downsides of overshooting evolutionary advantage

Dr. Lisle goes in depth about why nature has selected for subjective experiences.  The question is as follows: What is your take on why a subjective experience would have been selected for, as opposed to animals simply being like machines with no subjective experience inside?  More importantly, what is your take on how a subjective experience can possibly be created in the mind? How could neurons firing create a personal experience? Next, he tackles this broad few questions: Why were we given the intellectual capacity to overshoot our evolutionary advantage and create inventions that cause our demise?  Why would our minds become so advanced to create a world where we live with and around multiple pleasure traps daily, where even the strictest, most conscientious of us will fall prey to decision fatigue and give in to a few of these traps, thus affecting our happiness? Why do they have the capacity to do this? It seems as though we would have been happier animals as a species with a little less intellect.
