but the analogy to cars does not hold. They're not extensions to our legs in a genuine sense of the term. They don't improve, or interact with our physical capacities. On the contrary, they atrophy our legs, make us fatter, and produce urban pollution.

They're not a technology that enhances or melts with the human who uses it, it doesn't vanish into the background, the car doesn't even evolve much, rather the environment changes to fit the car, if anything hindering evolution, it displaces the natural ecosystem, it doesn't become part of it.

The same can be said about technologies weakening memory. They look like an enhancement maybe, but they may actually just cause impairment of function, becoming a crutch.

Your claim, that cars doesn’t become part of the ecosystem, got me thinking of this clip:
