Exactly? It's impossible to know what other people are thinking, so free will, will always exist.
Unless someone left a note or something, but that still wouldn't be 100% probability
Okay, when he is discussing the possibility of "someone" knowing all the variables, he is probably not discussing a human being, but instead a higher being. So if this higher being exists, and has the capability to see all of the variables at hand, then it would know for a fact that in each circumstance what you as a human being WOULD do, and WHAT exact choice you would make in each circumstance, therefore eliminating free will completely.
Now, if you do not believe in a higher being that is capable of that, well good for you. I dont have faith in one either, but i accept the possibility that a being may exist. I just read this story yesterday that i think you and the OP would find interesting:
