Perception, Evolution and the Brain

Loved the first 3/4 of this talk...but why do we want/need brain 2.0? i dont get why what we have needs to be improved/changed? i wish more people could fall in love with everything we already have! Then maybe they would want to explore and protect the biodiversity and evolutionary heritage of our planet instead of trying to get more and more lost in our own little worlds...
PS: The tetrachromatism section was my favorite, here is another great article on it with lots of good links: Do women perceive color different than men? and for more optical illusions go to Optical Illusions powered by our evolution in a 3D world

From the youtube site:
David Eagleman, PhD, neuroscientist, Tom Slick Research Award in Consciousness recipient, and best-selling author of SUM: Forty Tales from the Afterlives, shared his thoughts on "The Future of Reality." Dr. Eagleman gave compelling examples of how reality is a matter of individual perception and how Nature's adaptions function as "plug ins" for the brain.
