Watched this last night and got to thinking about the ending. It seems the robots found a way to manipulate the space-time continuum to take a consciousness from the past and put it in the new body. It isn't just a copy, but actually "you". Problem was, the process was deemed a failure because for reasons they couldn't avoid the consciousness extracted from the past could not exist beyond that one day. Arguably, even if they put that consciousness on an artificial body, it would also simply become blank after that period of time. I'm lost. If they could tap into the space/time, why would there be a limit of one day? From my understanding, space/time continues, it doesn't stop. If they could "lock" on to that particular space/time wave, wouldn't that extracted consciousness continue on and live out what the original wave was created on? Kind of like a 4th dimension, whereas you can not create a new conscious, but you would observe what had occurred in the past. Hope this makes sense....wanted to get somebody else's take on it.
