According to Ray:

“In my mind, we will ultimately saturate all of the matter and energy in our area of the universe with our intelligence, and I suppose you could say that's an end in itself. All of this dumb matter and energy around us will wake up and become sublimely intelligent. Then it will spread out to the whole universe at the fastest speed information can flow. And one could make an argument that it's not going to take an infinitely long time because there may be other ways to get to other parts of the universe through shortcuts like wormholes, which physics has postulated. Eventually the whole universe will, essentially, wake up.”
