How much do you figure seeing one's own future would change it into a future that seeing it doesn't change? I'd figure that it'd kinda balance out while your perception of time itself changes into something completely alien.
How much does ignorance of the future play into itself?
Will you not run into some kind of a catch-22 issue here?
I imagine such a power being present in someone effectively processing countless unseen trials, like that of a program, filing it down done until it falls into the deterministic framework it'd need to exist in the first place, a situation where seeing into the future changes nothing. It kind of ends up working out like Groundhog Day, but without all that expended effort from physically witnessing the time loops.
To have it be otherwise would have your future sight be inconsistent, changing every single time you use that power. Your seeing the future in such a case would seem no different than daydreaming, albeit with a few surprisingly accurate clues, since seeing said future would influence all of your decisions to the point of massive butterfly effect tangents.
If seeing you ate pizza for breakfast one morning makes you eat Cheerio's instead, you could have a very different day ahead of you.
They've that Russian theory (Novikov self-consistency principle) that goes into solving the grandfather paradox with a similar idea.
I've never read that one.
I'd mostly been going with The Grandfather Paradox being resolved with "You clearly failed to accomplish your goal", whether because of multiple instances of the self fighting itself to make it stable (if not "Time Cops" or something silly like that that otherwise intervenes with the path)... or simply because the goal itself wasn't doable through other seemingly disconnected factors. It doesn't answer the hypothetical that's posed of "Okay, but what if I did succeed, what then?", it just throws a small degree of unfalsifiability onto Determinism.
It's similar to the "Could God make an object even He couldn't lift?" kinds of questions, where the answer in a simpler form can be "Yes, for the moment" in that it doesn't technically answer the question in a truly conclusive way.
