Thank you for clarifying what I have wondered. In most of these videos it appears as if the molecules have an intent and act on a plan. It makes me think "how do they know to do that".

OK to extra clarify there are techniques to make the drunken walk more efficient. You might compartmentalize interacting bits into a smaller compartment which scales with the cube of the compartment ratio. You might anchor the participants in an interaction to a membrane, which turns a ~>6 dof search into a ~>3 dof (x, y, rotation) search. You might anchor the participants to a filament or DNA which makes the search a ~> 1 dof search.

If you just listen to the narrative of most of these videos, there is all sorts of agency referenced in the vocabulary. When in reality it's like a bunch of tiny magnets of indescribably complex geometry bashed around in a box until an eyeball pops out.
