If you want to compare humans moving through decision space to bacteria tumbling through physical space I suppose it's one way to think about how humans act but honestly that's a lot of text for a trivial kind of system that you can apply to almost anything. You can probably look at cars in traffic like this as well.

It's so vague and general of an idea that it's almost a truism. I don't think it provides anything meaningful in regards to figuring out the actual complexity of human behavior both individually or collectively.

And I think this kind of over-generalization that is a little bit vapid has been a trend because there's simply not been a lot of theoretical progress when it comes to the functioning of the human mind.

When people use this kind of thinking to apply it to artificial intelligence I always think, why not just ditch intelligence and build a physics simulator? Clearly intelligence is somewhere in the subspace of simulating the physical world, so why bother? It doesn't add much to understanding anything in particular.
