With the entire Universe made into a giant, highly efficient supercomputer, AI and human hybrids (so integrated that, in truth it will be a new category of "life") would have both supreme intelligence and physical control over the Universe. It would open up all sorts of new possibilities, including abrogation of the laws of Physics, multiple omniversal and Godversal computer minds, interdimensional travel, and possible infinite extension of existence (true immortality).
