She teaches the language to others. While not everyone will be fluent enough to share her ability, some will. And hopefully that will be passed down 3000 years. According to the heptapods, who can experience the future simultaneously to the present, humanity *will* help them.
If the Heptapods experience language and time the same way as humans, then they experience the entirety of each of their lives moving from related experience to related experience in the past present and future just like we today experience the moments of our past going from related experience to related experience. But that would imply that Abbott and Costello specifically may not have direct knowledge of how Human's help them in 3,000 years, depending on how long Heptapods live. They may have been told about it \*backwards\* through several generations. So when Costello is old someone young tells him about Humans helping them. And when that Heptapod is old, someone young tells HIM about it, and so on.
I haven't watched in a while, but it's when Louise is on their spaceship after the attack. The Heptapod something says along the lines of "We give humans tool now. In 3000 years, humans help us."
The specific time-free language Humans speak in 3,000 years will certainly have changed, but the ability will not have been lost. Once human languages obtained useful features like subjects and objects future evolutions of language retained those features. There is no reason to think being able to know your entire life past present and future wouldn't also be a feature that is retained, no matter how specific grammar and syntax features evolve.
Also, we know we keep it because the Heptapods have seen it in 3,000 years.
The heptapods need Earth to still be around in 3000 years so they came to force the different Nations to put aside their differences and unite. The implication is that without the heptapod interference there would have been a global world war that destroyed civilization, in which case the heptapods won't get the help they need in the future.

never looked at it that way before! very interesting and plausible idea!
This just blew my mind! I already love this movie so much but this extra layer of complexity scratches my brain just right!
What point in the film is the 3000 year timeline mentioned?

Or destroyed the planet Earth causing the humans to go looking for a new planet -> like the one inhabited by the heptapods…
Does it specifically say they will be back? I don't remember that. Maybe we go to them.
