Language Development During Interstellar Travel

I think another aspect which is somewhat ignored is that presumably space-faring humans could take libraries of audio and video content with them, which was not an option for Polynesians spreading to new islands. And I think we just don't know much about the actual rate of language change in environments which can include recorded spoken speech. If Chaucer had recorded an audiobook perhaps modern english speakers would be comfortable with middle english.
This is good! More diversity means more chance of surviving catastrophes, whether they're physical, biological, or memetic. And it makes the world more interesting.
It increases survivability against localized disasters but it remains to be seen whether that holds for the overall survivability of an interstellar species. All it takes is one demagogue on one planet with relativistic projectiles and a generations old grudge to wipe out most if not all of human civilization.
Sure it'd take decades/centuries for the weapon to strike and the demagogue and his followers would be dead by then, but that doesn't really change anything for humanity's chances. For bonus points, this demagogue exhausted his planet's resources by building an arsenal of tens of thousands of projectiles - enough to hit every potentially habitable world in colonization range (which is always going to be lower than the reach of aforementioned projectile due to pesky life support) out of spite.
Sound familiar?
But by the time such a voyage is possible, content creation will likely be entirely virtual, so wouldn't need much room on the ship.
In some sense, the crew will be like a small group of survivors living in the ruins of a great empire. They see what their ancestors were capable of, but they are unable to replicate most of it. The legacy content in the old Netflix library was created by a society with the same technology but vastly superior resources. Its creators were often more talented than the best and the brightest of the current generation, and they certainly could draw on a much wider range of life experiences.
I'm willing to bet in 50 years, software will be able to fully generate new episodes of TV shows, incorporating reviews of the previous episodes. Maybe everyone watches the same generated storyline so they can share the experience and talk about it, or maybe each episode will be tailored to your specific tastes.
Point is that I doubt "running out of content" will ever be a serious concern for long-duration travel again.
Historically oral language has of course come first, and then you just need to find a writing system from somewhere. Which explains why almost every Asian country used Chinese writing at some point in its history despite most of the languages being completely unrelated.
I bet you if you locked a Scottish guy, and someone who speaks AAVE in the same room and they had to work together to escape they easily could. If you slow down AAVE it's just normal English, along with repetition to emphasize certain points. But this varies wildly based upon where in the United States you live. In Los Angeles, a lot of these black kids grow up watching anime all day so it wouldn't surprise me to see a bit of Japanese make its way into AAVE.
Its so strange to me that people basically avoid recognizing that most African Americans simply speak a Southern dialect that has been able to persist outside the South because of de facto segregation.
