Is your future set in stone?

I have always thought that although we might be fated to have some experiences, ultimately our destiny is not set in stone. Along with that, I think that we have tremendous power to change our future. Recent discoveries in fields such as quantum physics give us the scientific seal of approval on ideas that you have more than one potential future in front of you. Here, professor of philosophy Daniel Dennet gives a fairly weighty but well worth watching lecture on free will, determinism (or the idea that we can’t escape our past) and evolution. The talk starts at around 13.50 so you can skip forward past the introductions.
