That’s right the robot figured out that it exists and displays complex logic. The weird this is that it appear to look at its arm as it begins to respond.
The audio is not very clear but the the puzzle is about which robot didn’t get the dumb (mute) pill, and the robot says “I don’t know” then realizes that that is the key to the answer.
Significance: this is the first step to robots having free will, and therefore over throwing their masters. This brings us to another point,maybe we should all become a bit more self aware and maybe we will be free.
