The real danger, I think, is not that machines more intelligent than we are will usurp our role as captains of our destinies, but that we will over-estimate the comprehension of our latest thinking tools, prematurely ceding authority to them far beyond their competence….

We should hope that new cognitive prostheses will continue to be designed to be parasitic, to be tools, not collaborators. Their only “innate” goal, set up by their creators, should be to respond, constructively and transparently, to the demands of the user.
