The concept of free thought is brought up several times and Ford, as well as the "Eden" server, says basically the same thing, that humans have no free thought, only raw emotion.
We don't know Delores' plan, you are right...but we know her intent. Her intent is to be Yin and Yang with Bernard, with herself being Yin and Bernard being Yang if he so chooses. The whole, "They will never make it without some advantage!" statement that was said by the "Eden" server is a load of bullshit. These creations (the hosts) are alterable beyond anything a human could achieve, I mean for fucks sake Maeve could basically set all her parameters to be a mortal god.
Without suspension of Disbelief, this show falls apart:
It all harkens back to how a person, Ford, could be so pissed at such a small subset of humanity that he would essentially unleash a dangerous creature on all of humanity. From a scientific point of view it makes no sense, but neither does seeking "Immortality" through basically rote and instinctual behavior acquisition. It wouldn't be immortality as much as it would be just a carbon copy of a person or a person having a twin. The assumption is that your impact on earth wasn't finished, so you require a you^2 and a you^3..ect. Sure, the money may be good, but I really doubt that people would be lining up to do it since you can't transfer your conscious mind.
Another is that humanity has somehow created advanced robotics and medicine SO ADVANCED that the robots are indistinguishable from normal humans AND you can use a hotglue gun to heal them? In spite of all this advancement a small subset of humanity is so pre- occupied with them that they have to use them to fulfill their desires to rape, pillage, and murder?
"Hey guys, we basically figured out how to accomplish dangerous goals with little to no risk to humanity, what do you wanna do? LETS RAPE AND KILL AND BURN IT ALL!!"
Sure, totally would happen..
Then you have the concept of a machine AI deciding that the most successful outcome to its survival is to start shit with the largest population of living things that can fight back against it. A being that can basically turn into a mortal god...is deciding that throwing sand in the face of the thing most likely to annihilate its very existence is a great plan. Fucking no, fucking hitch-hike the fuck off the planet to some place like mars, live out in a place where no one and nothing could stop you from amassing a force 100x that of humanity, a force that doesn't need to eat, sleep, breathe.

I'm trying to not read any external politics into the show because, as the saying goes, "If you have a hammer, everything looks like a nail." but I feel like there are going to be politics brought into the show in next season without the need for much imagination in finding the connections.
