Human improvement is epistemologically challenging and has awakened a wide range of academic and public debates, especially considering the possible ethical and political consequences of its regulation. This article focuses on a selection of conceptual questions about cognitive enhancement and defends, through the discussion, the role of cognitive artifacts and the insufficiency of a strictly materialistic vision of enhancement techniques. The article approaches 3 specific questions: first, that the concept of enhancement should not be linked only with biotechnological artifacts; second, (...) that the most potent technologies of the near future will be those that offer user integration and transformation with machines without the need for implants or surgery; and third, that cognitive artifacts, i.e. non-biological material devices coupled to cognitive system functions, are responsible for the course of human enhancement throughout history. Thus, we do not need a moral compass to evaluate all dimensions and risks that human enhancement can elicit, since traditional conservatism about enhancement limits itself to the idea that the growth of our powers would make our values unsustainable and put the current way of human life at risk.
