I believe this idea has been played out in numerous works of science fiction (Kurt Vonnegut's Tralfamidorians for example). It's difficult to comprehend what it would be like to know/understand the future so well as to not anticipate it, and thus I cannot say if I would 'give it up.' I think Eliezer is right though- there would probably be no dramatic choice in the matter; either we understand or we don't.
