There will need to be a major leap again before we can move back to an exponential curve versus the logarithmic one we are moving towards now. Of course, once we have that new technology would Moore's law even be applicable?
And that sir, is the million dollar question. When you have full autonomous, self aware, self coding artificial intelligence that can think 20,000 years in relative form for every week of human level thinking, you have then reached the level of what we can no longer comprehend. At least, I highly doubt we can comprehend what this would entail, and the scary part, is we are well on the way of achieving this.
