(Actually, even your quotation in this post already says that: "Much more important than its philosophical implications, however, would be its practical effects. Creating superintelligence may be the last invention that humans will ever need to make, since superintelligences could themselves take care of further scientific and technological development. They would do so more effectively than humans."

Only "more effectively", should be "way more effectively, qualitatively more effectively, incomparably more effectively".)
