> ... so which task is the final step to reach singularity?

From Vinge's essay where I first heard of the term: I. J. Good2 wrote: "Let an ultraintelligent machine be defined as a machine that can far surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an "intelligence explosion," and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make, provided that the machine is docile enough to tell us how to keep it under control. . . . It is more probable than not that, within the twentieth century, an ultraintelligent machine will be built and that it will be the last invention that man need make."

So the final step is an AI that can generate other AIs of greater capacity in terms of compute/time, computer/$, utility/$, etc.
