I admit this is beyond my knowledge, but maybe the following is rather intuitive and not too incorrect. "Flipping one bit" is not enough. You don't make any progress toward a solution if you only keep flipping the same bit. At the least, you need to decide to flip which bit. That is also information, information that is not stored in the resultant bit array where you flipped one bit. More in general, I agree with Rob that this is not a physics course, and this is just a thought I had and wanted to share. You can't object to scientific theories on the basis that you did not study them properly. It might have a bit of a Socratic feel to it, but it quite falls short of the real thing. Physics and computation at this level are pretty unintuitive, I think. Maybe my little attempt to introduce some intuition about information content is grossly wrong, and maybe it's a folly to attempt intuition at all.
