I also don't think humans have free will. BUT, I think that fact is utterly meaningless. We feel like we have free will and we will never (and I'm saying never) be able to measure all the variables in the human brain such that we can accurately predict all future actions and decision-making. There are just too many variables at the cellular and circuit levels for us to accurately measure and model. However, we can already predict simple decision-making in monkeys and even influence it with tiny, well-placed electrodes. A friend of mine does this kind of research and it is awesome, but scary.

I do think at some point we will create artificial intelligence that believes it has free will. At which point it will become more obvious that we ourselves don't.
