But he's right, we don't have free will, at least as far as physics is concerned. Given a powerful enough computer, the motion, charge, spin, etc. of every atom could be determined, including those that make up the neurons in your brain. Thus, the decision-making process happening in your mind is itself deterministic. However, there are far too many variables for this to ever be computed, so the way our brains have evolved, we perceive the world with free will.
I like the way Christopher Hitchens put it:
'You have no choice but to have free will'

You’ve fallen into the trap of thinking you are separate from the universe.
You are one with the universe. Indeed, you *are* the universe.
Tat tvam asi.
Meaningless woo-woo in the context of freewill vs determinism discussion. But inspiring nonetheless; same as this:

The opposite is true. People who believe in free will separate themselves from the universe. The universe is clearly deterministic and so are we.
