An actual 'Westworld' isn't reality yet, but not everything about the show is science fiction

However, technologies that mimic social cues and dialogue can already be seen today, Riedel said. "What the AI looks like in'Westworld' is in some ways what game companies are trying to do in virtual worlds," Riedel said. In the show "Westworld," the hosts are given pre-installed storylines that are triggered when a person interacts with them. It's similar to how game mechanics work in action role-playing video games like "Borderlands," Riedel said. Still, "Westworld's" missions are much more complex than what our current technology enables, he said.
