Good up until the end. Stupid moral. Not a very good analog of slavery. The exocomps weren't the "indigenous" species. They were brought with humans, whom they killed. Two options, they're not really people, in which case they're not to blame for their actions, and thus they get their minds completely wiped or they're destroyed. The other option is that they are people, in which case they are not justified in their actions . The final couple minutes were grating.
"Hey, folks, your machines turned on you and killed your family. Now they have greater rights than you because the writer wanted to say something about slavery."
