Ruth Evans takes an historical perspective on Andy Clark's natural-born cyborgs argument, and that "human cognition is not just embodied but embedded: not mind in body, but both mind and body enmeshed in a wider environment of ever-growing complexity that we create and exploit to make ourselves smarter."

From the abstract:

The philosopher and cognitive scientist Andy Clark has argued that humans have always been ‘natural-born cyborgs,’ that is, they have always collaborated and merged with non-biological props and aids in order to find better environments for thinking. These ‘mindware’ upgrades (I borrow the term ‘mindware’ from Clark, 2001) extend beyond the fusions of the organic and technological that posthumanist theory imagines as our future. Moreover, these external aids do not remain external to our minds; they interact with them to effect profound changes in their internal architecture. Medieval artificial memory systems provide evidence for just this kind of cognitive interaction. But because medieval people conceived of their relationship to technology in fundamentally different ways, we need also to attend to larger epistemic frameworks when we analyze historically contingent forms of mindware upgrade. What cultural history adds to our understanding of embedded cognition is not only a recognition of our cyborg past but a historicized understanding of human reality.

This reminds me some of the work of the cognitive anthropology crowd, which I find necessarily speculative but extremely ambitious and interesting.
