This is an interesting if somewhat meaningless hypothesis. It doesn't make
any difference whether it is true or not!

If I am crossing a road when I suddenly notice a bus coming faster than
expected, I WILL take evasive action. I believe that my decisions will
affect what happens.

Also, I think there are some significant problems with your position that
if you had a big enough calculator then you could predict events next week.
For "simple" stuff like would a particular space ship move to a
position where it could loop around Mars, then yes, the big calculator will
work.

For stuff like predicting the weather, you would need REALLY REALLY
PRECISELY known starting conditions. Measuring all these at one instant
would interfere with the initial conditions.
