The entire movie embodies Cassette Futurism, but IMO the self-destruct sequence is particularly great. The entire process looks so satisfying that I probably wouldn’t be able to stop myself from running it if I were one of the crew.

This is how a self-destruction system ought to be. An extremely long, and somewhat complicated series of hoops. Because you seriously don’t want to just accidentally flip a plastic cap and hit a button or even require a key or two.
And the only movie to depict one this way is the one where you want the ship to blow up and not be miraculously stopped at the final seconds. The tension!
