While that might be the limit for classical computers, I disagree with
the "strong statement" since at small scales there are not enough
particles for the statistical definition of kT to be meaningful - i.e.
Especially so for systems not at equilibrium, such as biological ones.
The article linked below contains another stong statement - "the
actomyosin vesicle transport system does exhibit the quantum coherence
and entanglement necessary for quantum computation within a single
neuron." Any takers?
