This is where actually watching “Westworld” matters. The pleasure of entertainment aside, the makers of the series have produced a powerful work of philosophy. It’s one thing to sit in a seminar and argue about what it would mean, morally, if robots were conscious. It’s quite another to witness the torments of such creatures, as portrayed by actors such as Evan Rachel Wood and Thandie Newton. You may still raise the question intellectually, but in your heart and your gut, you already know the answer.
