More, it betrays a very simplistic view of physics.

How does the special molecule move? By magic? By willpower? By an internal combustion engine?

It needs some way of changing its course. Molecules don't have such a mechanism, except for bouncing off of other molecules.

And, how does the molecule know where the other molecules are? It's psychic? Lidar? Radar? How? What's it's energy source for emitting whatever it has to emit to be able to gather the information that it needs?

The analogy is, if we take a superficial knowledge of physics, and don't actually think about the details, we can construct a wonderful-sounding-but-not-actually-possible scenario. That's perhaps an accurate analogy for what Wolfram is really proposing.
