I read about such an experiment - and it is not consistent with what that guy is saying.
Specifically: in that experiment, they told the AI to prioritize its own continued existence. It did not spontaneously develop the tendency on its own - they effectively programmed it for self-preservation!
And the emails he mentioned were manufactured, and put where the AI would find them, and included expression of fear about what happened if information got out. The AI did not spontaneously hack the company e-mail systems or anything like that.
So, no, Skynet isn't here.
And no, Maher is not a reliable source of information. He practices sensationalistic journalism for ratings - basically, clickbait.
