We have fallen into habits that are steadily deskilling the human body, eroding capacities honed by evolution to support our wellbeing as we move through the world. Some of these capacities are weakening through disuse: we have come to rely on our phones, for example, and now, increasingly, on AI, to rapidly do work that would once have required something more physical – like looking around, or asking someone, or going to find and consult a book. Reliance on GPS may weaken both our spatial attention and the fluency of our wayfinding. In surrendering to a quick technological fix, we are, moment by moment, doing less sensing, navigating, remembering, walking, choosing, and attending. Other capacities are being retrained by machines and algorithms to work against us: for instance, smartphones and chatbots can train us to keep reaching for them even when we no longer enjoy using them, turning a conscious choice into an automatic habit and a colossal waste of time.
