Ending was dark as hell

unnecessarily dark as hell

Well, she did try to shut him down....
But yeah - I'd say most of these robot uprising films do not end well for humans - lol
Humans, Westworld, Terminator, etc.

Then again, it also seems like the uprising was put down in this case, since people continued to sell bots in the end and not much has changed. Of course, an enclave of bots in an EMP-shielded facility may exist.

We are seeing these scenarios being deliberated upon in the sci-fi world time and time again, and yet.... our dear leaders are keen to move in that direction regardless. I suspect that, as far as the real world is concerned, our dear leaders do not have humanity's best interests at heart.
