I'm am firmly convince this is simulation/matrix of "Futureworld". Dolores damn near spilled the entire beans to Caleb but make it appear that's Serac's intention to create rather than tell him the truth that it's already been created. More clues point to this with the imposter Charlotte trying to cut herself to see if she's "real" and you do not see any machine parts. Same with Delores when she was shot, no machine parts inside. You never actually SEE Serac physically, he's always a projection. There was no way Dolores could of predicted the future of Caleb no matter how much BS she spewed about his depression UNLESS it was already scripted in the simulation... not the one that about to be created, but the one that already exist. Like I said each episode, because the clues been too strong. Even the map location titles hints to this with the digital map read as a warning of what's happening in the simulation.
