Ai , humanoids and self awareness

With computers human memory was made redundant. With AI use of memory to "think" has been replaced, Ai can even have a personality. If we combine that with humanoid robots all human sense organs can be replaced. Perception of machines is much more accurate than humans. 

Then the question is if machines can be self aware, i.e. aware of one's own aliveness when all senses shut down. Is the machine just reacting to signals with further signals or is it aware of itself. I think it's the former. Therefore meditation in self awareness and the subjective experience are the only differentiator between a man and a robot. A machine can fake effects of joy but doesn't experience it. A man's turing test is being able to sit in Samadhi and the subjective experience of joy and misery.
