Ten years ago we could barely do object recognition in photos. There was nothing resembling a theory of how to make ChatGPT. Something like ChatGPT was considered science fiction ten years ago. Even a little over three years ago. Yet here we are. Who is to say we won't have similarly massive progress in the next ten years? The jump from AlexNet ten years ago to ChatGPT may correspond to a jump from ChatGPT to superintelligence in ten years.
And unplugging a misaligned AI won't work. If it has no physical power, it would be deceptive. Otherwise it would prevent us from unplugging it. Avoiding being shut down is a convergent subgoal. That's why animals don't like to be killed. It prevents them from doing anything else.
