'''Wrong!''' you think? <br>
Well yes, in the context of [[rising surface area]] friction really does rise when going down to the the nanoscale, but ...
* ... that is only if we'd fill up a whole macroscopic volume densely with nanomachinery (not necessary in [[]convergent assembly]) and
* ... in other regards it shrinks.

First there is [[superlubricity]], <br>
but there are other perhaps more deep reasons for friction to diminish at the nanoscale.
Its about the issue that in systems small enough 
* there are few degrees of freedom for energy to be dispersed into (thermalized/devaluated/dissipated) and
* there can be the quantum effect of a minimum activation energy that needs to be overcome before a degree of freedom becomes available. (This can be seem in the heat capacity of polyatomic gases where steps represent the "quantum activation" of degrees of freedom).
