Having a smart-but-no-smartass intern by my side, that is always eager to help, that is at the very least superficially knowledgeable about most things, that autonomously gets better at absolutely everything non-physical (yet), that is loyal yet immediately replaceable should I get bored with it or should a better intern pop up overnight (literally happened yesterday with qwen3), that never tires or gets annoyed at me.... well that's pretty exciting.
What a weird and deshumanizing thing to say. Slaves are definitely people, a machine definitely isn't.
Moreover, slaves aren't productive over the medium/long term. You don't get useful and lengthy performance from raw coercion, the same way you don't get truthful and actionable intelligence from torturing prisoners.
So no, an LLM has very little in common with a slave.
