While I find the issue interesting, it also strikes me as kind of moot. If I do or don't have free will, how could I know? Because if I don't, I still exist and make decisions and take action and live my life. If I am unwittingly following a path that I cannot deviate from, how would I know?
Researchers are learning about the human brain all the time, but it's clear they are just starting to understand it. It does seem as if a lot of who we are is trapped in a subconscious that we have very little (if any) access to. So perhaps free will is an illusion. Again, I can't know this. And would I want to live in a world where we just excuse people's behavior because they are "unable to direct themselves"? No. I don't. I prefer to think that I have some say in who I am and what I become.
