It's understandable that one of the portions of the discussion that has attracted the most attention (and ire) is the question of Free Will. There are many occasions in history where scientific discoveries have forced us to re-examine our own cherished assumptions. In such situations it is not unusual for people to initially seek ways to reject this information, and even to attack those who present it, as a sort of protective disgust-reflex, instead of engaging with this new data in order to ask questions and consider new possibilities (good as well as bad).
Apparently the way Dr. Greene himself handles this sense of intuitive conflict in his own life, is to go on living with a healthy dose of curiosity and humor, accepting that things may not always be quite as our intuition tells us they should be, while recognizing that we can honor the importance of Free Will as a part of our subjective experience of living, within our limited ability to sense and intuitively grasp the underlying physics at work in each moment. Ironically, he as a scientist seems more willing to accept a certain amount of paradox in life than some religiously-minded folks are.
The question of Choice is a thorny one for us humans, and similar issues (and strong opinions) arise in discussions of psychology and neuroscience, and of crime, mental illness, and punishment. Not to mention theological discussions surrounding ancient notions such as "karma" and "sin". We can be sure that as artificial intelligence continues to develop, there will even more discussion of the intersection of science and Free Will.
