We will need AI to take our species to the next level. Unfortunately human brains are only capable of so much, and we aren't naturally evolving fast enough.
AI will be required to solve complex problems that we can't even grasp and filter answers down to a level we can comprehend. Problems like manipulating our genome precisely will take problem solving beyond what our brains can do, even in a lifetime
Today we rely on programmers and engineers to be the interface between the computing power and humanity, in the future the programmers will interface with AI that is controlling the computer power.
