And I’m saying that it’s not possible under any understanding of time travel or causality to perfect history for the best possible future outcome, because doing so would negate the necessity for time travel. Unless you want to argue that this is why time travel doesn’t exist, because the past is already a perfect state to never necessitate time travel. But that’s the only objective measure of “perfection” that is internally consistent, and I think we would both agree that from our perspective, the past is far from perfect.
Ok but then going back to study and learn would probably include a policy of non-intervention. So how would you know we aren’t constantly surrounded by time travelers blending in?
That’s kind of the entire conversation we’re having. If time travel exists, then why hasn’t the past been improved, led to is it even possible to improve on the past, led to would time travelers be able to change anything, led to how would we know if time travel exists. Is it important? Only if you want to answer any of the questions we’ve asked. What would we anticipate they do? That’s all of the questions we’ve asked.

Time travel is it’s own reward. We can study Ancient Rome or anything. Space probes sent to the extreme past would be very useful.
I do not expect “kill Hitler” or “fix my love life” to be the driving force in the multi billion dollar effort for time travel.

We won’t unless they screw up.
Is our detection of them important? It is disappointing to not have obvious time travelers.
What would one anticipate a time traveler to do in the current time?
