Think of the modern music playing on the player piano ("The House of the Rising Sun," "Back to Black," "Fake Plastic Trees," "Black Hole Sun"); the literary references (Mary Shelley’s Frankenstein in Episode 8, Shakespeare in the pilot); the art references (Da Vinci's Vitruvian Man, Michelangelo's Creation of Adam); callbacks to the two Westworld movies (Elsie finding statues straight out of Roman World and Medieval World in Episode 6, Yul Brynner's Gunslinger in the old offices in the same episode, the samurai in the finale); callbacks to other movies (Jurassic Park with Felix's "That's it. Come on, little one" from Episode 5); and references to video games (BioShock, Red Dead Redemption series, etc.). All of those little Easter eggs were nice ways to fall down a Westworld subreddit rabbit hole for days, but those distractions weren't, to use the Man in Black's parlance, the true "deeper game."
That deeper game brought up discussions usually reserved for college philosophy majors during late-night drug-smoking sessions. Of course, the ideas of the hosts' bicameralism, and of understanding the mind through memories passed from the right side to the left side without metaconsciousness or introspection, play a large role -- but what about the idea of self-actualization? That the maze is actually your consciousness, and the closer you get to the center, the more you understand that the voice inside your head was yours all along? (From Ford: "Consciousness isn't a journey upward but a journey inward, not a pyramid but a maze.")
Or the idea of freedom, of who is really free and who is being controlled? Maeve's quest to be free ends with her making the choice (On her own? Or because she was programmed to? STAY TUNED NEXT SEASON) to get off the train and come back to the park. But, as Ford says, we humans think we’re special in the way "we perceive the world, and yet we live in loops, as tight and as closed as the hosts do, seldom questioning our choices, content, for the most part, to be told what to do next."
Humans go to the park because the idea is that without rules, we can be as free as we ever will be, and in that freedom we will find our true selves. But doesn’t that entire concept further solidify the fact that our normal lives are not actually "free"? And what does it say about our "true" selves that most humans spend their time in the park either killing or fucking things? Wait, is this actually a commentary on the state of the internet in 2016?
