Except she knows exactly when the person she's communing with is receiving the message (To you, 2,000 years from now), which she could only know with foresight of the future.

Neetaku wrote: Yes, technically the Attack Titan's ability has a use in the sense that the future can only happen in the very specific ways it does because someone knows the future, but I would argue that it is still a redundant ability. What is the point of having the ability to see what happens in the future if there is absolutely no way you can use that information to try to change it? Normally having the ability to see the future would be astronomically useful, because it would give the main character the ability to see something which happens in the future (let's say the death of a friend or loved one) and then they can use that knowledge to try to prevent it. But Eren's ability to see the future does not grant him any such power. You're not appreciating the way this ability passively excludes the future he sees from happening in a way which the attack titan doesn't want to happen, assuming he was involved in it (which he always is by definition, since he's seeing the memories of a future attack titan) and fully in control of the situation (which he isn't always, since he's only a single human/titan and not all powerful. For example Grisha cannot save Carla because she wasn't involved in the future memories he saw and he was too far away to help when he received them in any case).

For example, a vision of a future where Eren willingly touches Zeke and the euthanasia plan actually worked COULD NOT HAVE HAPPENED. Eren's knowledge that everyone would be euthanized gives him no motivation to touch Zeke; meaning the events that constitute that future could never happen and thus Eren doesn't see it in a vision in the first place. He only sees visions of a future that happens the way he wants to happen because that is the ONLY FUTURE HE HAS THE MOTIVATION TO CAUSE TO HAPPEN. It's heavily speculated that this is also the reason why the attack titan never fell into Marley's hands.

You see it as a situation where the future 'cannot be changed', I see it as a situation where the future was always distorted in favour of the attack titan from the start simply by virtue of it possessing this ability. So in a sense it 'already has changed', but not really since it was always that way from the start.

You instead want him to wield the influence after the fact in the form of an improved alternate timeline, but that's not the time model this series is using. Everything we've seen suggests there is only one timeline, and due to the attack titan's foresight it is always constructed in a way that favours the attack titan.
