I’d be interested in hearing about multiple slime moulds at work within the same network space. Individually, I don’t think the slime mould experiment tells us much with respect to congestion and efficiency constraints. A transport network without congestion and efficiency contraints would not be a problem for the human commuter who could equally determine an efficient route from A to B, and include options C & D as alternative routes.
Still, I am impressed with slime moulds for their “intelligence” and mapping potential.

Dave Snowden talks elsewhere about how our role is to feed the feedback loops that are desirable and mute the ones that are not. Nudging the formation of strange attractors is an important role for leaders and I often use the analogy of a farmer who plants and grows things, not by making the things grow, but by being attentive to the conditions at all scales, adding water if it doesn’t rain enough, digging trenches to drain water if it’s too wet, etc.
