CONCEPT
Co-Intelligence
Ethan Mollick’s name for the third option beyond tool and rival—the deliberate partnership between human judgment and machine capability in which neither party alone can achieve what both together produce.
The dominant frames for thinking about advanced AI treat intelligence as a scarce, zero-sum resource. In the first frame, the machine is a sophisticated tool: inert, deterministic, doing exactly what it is told. In the second, the machine is a rival: a competitor for the cognitive work that defines human worth, its advance up the capability axis a direct threat to every human practitioner below the waterline.
Mollick rejects both because both misdescribe the actual experience of using these systems. The systems do not behave like tools: they surprise, they improvise, they occasionally produce something better than what was asked for and occasionally produce something confidently wrong, and they present every surface cue of a personality, however much the practitioner knows the personality is an artifact of statistical training. Nor do they behave like rivals: they have no projects of their own, no stake in the outcome, no will that competes with the user's. Co-intelligence is Mollick's name for the third option: a partnership between unlike minds
