I strictly don't believe in sentience being possible for robots. I think robots can and may eventually pass the Turing test to a meaningful degree - but only on the end of imitating/fooling us.

So this question is more like would I like to destroy a couple of expensive robots or kill someone. I chose to 'kill' the robots. Some might see this as cheating or not in the spirit of the question being asked - for me, I can't and will never concede 'programmable sentience' as any sort of reality.
