The door controls in Ressik are sci-fi beepy dealies, as if the director realized at the last minute they needed something to visually indicate this is a space-age civilization. Because… look at everything else!
Is the anachronistic depiction of Ressik just an artistic choice, or is there some deeper meaning behind it?
And they suddenly have the ability to download memories into alien species! This would make schools obsolete, and potentially give them the ability to train the entire population on chemistry/biochemistry/biology. They could have built Silos and possibly survived underground if everyone could be insta-programmed with long term survival skills.
The correct answer of course is “don’t think about it!”
On top of that, ‘give one person memory of our civilization that they can’t really share with anyone adequately except knowing how to play this flute’ may not be the best way to memorialize a planet.
