[FRIAM] Any non-biological complex systems?

[Steven A Smith]

Russ -

I think your message got lost in the "uncanny valley"... the 
conversation has been so rich that this contribution (by the instigating 
author of the thread) did get lost to it's relative obviousness.   I 
know *I* read through it and nodded my head but instead felt compelled 
to respond to SG's post which *was* (I think) in response to this.

I have suggested a new thread and this type of question (dual-worldness) 
would probably be central to it.   I do hope others weigh in.
