The reason why we never meet time travelers is because our civilization ends before the technology can come to fruition. (lemmy.world)

Sort of similar to the Great Filter theory, but applied to time travel technology.

If time travel existed, why would anyone come to this time period where everything is fucked up?

And if the tech is regulated to stop altering the timeline, they could be here in disguise. Possibly literally invisible to us because they're only permitted to observe and not actually take part in anything. It could even be that time travel works like Paycheck and not The Time Machine, and you're just able to look into the future/past but not actual travel to it.

Or the branching timeline scenario in Back to the Future is the reality of things, so even if you went back in time to talk to yourself as a younger person, that happens in a totally different dimension than the one you were in when you yourself were a younger person.

Everyone is mentioning branching timeline of back to the future but the movie never follows that. Marty's parents are not getting together he ceases to exist. Biff brings book back and Marty goes right to that timeline. The movie is just cause and effect.

People bring it up because there is a scene in one of them where Doc Brown explains the branching timeline theory.
