Only to avoid catastrophe. But that could be a slippery slope as well. If I avoid catastrophe for myself, most certainly I will want to look into the future to avoid catastrophe for my family and then where does it end. Do I think, I would miss Aardvark's sports facts if he got hit by a bus so let me peer into the future and check if there is anything I need to warn him about. While maybe a noble effort, I don't want to spend my days searching the future for calamities that might occur.
