So, we all remember in the Doctor Who episode "Deep Breath" in series 8 with that weird half-face man. There was another question on the Stack Exchange about the scene of the half-face man's defeat, and that question inspired this question. So, we all know that the half-face man is a robot, so how could he go to heaven? That last scene showed him in this mysterious "Heaven" with Missy there, and even if it technically wasn't the real heaven, (rather a hard drive... thingy) how did the half-face man end up there if he was a robot? Being a robot, there was no form of spirit or even sentience that could render him in such a place. I know it was necessary to introduce that mysterious concept in the first episode, but couldn't they have introduced this "Heaven" in another, more realistic way? Possibly even by showing a citizen that was killed by the half-face man in heaven instead?
Because Heaven wasn't actually Heaven (e.g. in the Christian sense of an other-worldly place filled with spirits and souls), it was actually a Time Lord storage device filled with the mind-states of the recently dead, recorded and captured using technology...
by the Master/Missy as part of (what else?) an elaborate plot against the Doctor.
SEB: You're dead and, and this is what's next.
DOCTOR: A Gallifreyan hard drive. Time Lord technology.
That being the case, there seems to be no special restriction on a robotic intelligence being uploaded into the mind-sphere, any more than an organic intelligence can be uploaded.
