Westworld season 2 opener reinforces need for ethical AI (spoilers)

Tonight's premiere episode of Westworld season two is littered with bodies. It's a reminder of the consequences of what can go wrong when we put the race for technology ahead of ethics that governs what we should or shouldn't do with that technology. At the close of the last season, the AI hosts of Westworld gain independent sentience, and they rebel against their masters, slaughtering the humans who subjected them to inhumane treatment and allowed them to be used as the instruments for human resort goers to live out their (usually) worst fantasies. Editor's note: This story has some season two episode one story spoilers. Season two starts with more of the aftermath of that AI rebellion.
