A model trained on HN would spit out a 5 paragraph story about how minorities provide a negative ROI for cities. Or how the homeless need to removed from society.
Sure, but it would never do something actually bad, like raising the possibility that sexual harassment might, sometimes, be an issue, or questioning the value of phrenology.
Don't forget that it must also generate, at some point regardless of the topic, a new terminal emulator, and an extremely positive or extremely negative opinion about how blockchain can solve a problem.
Note that HN is included in the training data, see page 20.
