The only way maeves storyline works is if the repair teams are robots, which makes sense because why not have robots do the tedious repair work. In my mind, it's just all part of ford's overarching narrative, or shit that arnold set in motion years ago
With delores, I think she's roaming the park in present day completely broken, reliving multiple past storylines she's been involved in. None of what happens in her scenes can be taken as fact, which is kind of lame, but will hopefully have a payoff.
This is looking like it's coming down to Arnold wanting to free the robots because philosophically, because he believes them to be alive, and Ford wanting to keep them as slaves, because philosophically, he doesn't believe in consciousnesses anyways so who gives a shit.
