In light of the "adversarial poetry" revelations it's dawned on me that maybe Orwell's Newspeak is not an attempt to restrict possible thoughts. It's an effort to _sanitize inputs_ in a world where AI systems people no longer understand can be undermined and sabotaged by just the right (wrong?) kind of expressiveness.
That is to say, Orwellian Newspeak is a (justifiable, necessary?) safety measure in a world where AI-managed infrastructure can be subverted or repurposed by weaponized poetry.
