Your ability to plan into the future is polynomial; the future's ability to do things you didn't expect is exponential. Reasonably low factors on each, at least generally (sometimes reality goes through periods of a much larger factor making planning hard even in the short term), but they're still in different classes. Combined with the fact planning is not itself free and a lot of the rest of the analysis after this becomes pretty obvious.
