The digression is ridiculous, though, because it's explicitly shown in the movie that the Axiom is not "Edenic" in any way. The system is a non-sustainable repetion of what happened on earth. The humans are not happy. They are miserable and devolving in a floating time bomb, oblivious to the expiration date. This is all laid on pretty thick. It's even implied that they don't reproduce. It's like the people arguing random philosophical platitudes haven't even watched the movie being discussed.
If nothing else, the fact that no one has used a movie reference in the whole side discussion should be a giant red flag.
Here's a semi-hot take to get things back on track: The Day the Earth Stood Still is overrated. Everybody remembers the great opening and the great ending, sure. But the middle part where Klaatu tries to hide out on earth, befriend a kid, and figure out money is both silly and boring. There's basically a half hour of dead time that's just there to justify it being a movie instead of an episode of The Outer Limits. Still a classic, but there's a reason it's remembered as classic sci fi and not a cinematic masterpiece.
