The alternative is that you wind up with multiple AIs with different biases, people pick the ones that match their own biases, and we're not much better off. One presents stories about how drug users are unlikely to be convicted of violent crime, the other presents stories about how drug use leads to unsafe workplaces and road accidents. Both factually correct - like almost all news today - and both playing into people's biases and not solving the question of "do we legalise weed?" at all.
