Is the universe deterministic?

Read something interesting in an exercise submitted by a student I'm a teaching assistant for in an AI course. His thoughts were that since the physical laws are deterministic, then in the future a computer could make a 100% correct simulation of a human, which would mean that a computer can think. What do you guys think? Does Heisenberg's uncertainty principle have something to do with this and if so, how?

The universe is not ~~ontologically~~epistemologically\* deterministic. ie, a computer (or a demon as the question was first proposed) cannot calculate the future to arbitrary levels of accuracy. 

It may yet be metaphysically deterministic in that even though you can't at all calculate the future, if you were to "play out the tape" and then "rewind" and "play it back" the repeat would be the same as the first time through. Of course we don't have a way to time travel, so it's probably impossible to test the notion of whether the universe is metaphysically deterministic.
