 Still profitable near term applications that create progress merely accidentally (like molecular biology based medicine)
 should be kept the only forefronts of development. After all their focus can anytime quickly and permanently veer off sensible far term goals. Even in a way that strongly hiders further progress to those goals.

-While diffusion transport takes no energy for the motion the necessary energy expenditure for the capture from the solution and permanent fixture to the target surface must not be overlooked.
+=== Myth: "Transport at the nanoscale can only be done via diffusion transport" ===
-Diffusion transport speed is faster when temperature is higher but the temperature is limited by what the transported molecule can survive and the boiling point of the solvent (if unpressurized).
+The lack of fully guided transport in biological system does not imply their impossibility.<br>
-Diffusion transport speed is distance dependent. The farther the slower it gets.
+=== Myth: "Diffusion transport has superior efficiency to non-stochastic fully guided transport (e.g. on rails)" ===
-Diffusion on a lower dimensional subspace (e.g. a lipid membrane) can improve the situation.
+While diffusion transport takes no energy for the motion of transported molecules the necessary energy expenditure for the capture of transported molecules from the solution and subsequent permanent fixture to the target must not be overlooked.
 That is diffusion transport can be sped up by reducing the dimensionality of freedom of motion and or restricting the range of motion to regions.
 In biology motors work often by prevention of back reactions.

 If taken to the extreme one ends up with a one dimensional path with unidirectional erratic motion with unpredictable times for forward steps.
-By coupling many of these together in the background one ends up with predictable and continuous forward motion which is essentially what a machine phase systems is.
