Maybe it will help to say a few things about the way forward ...
I'll be getting back to Ashby's text directly -- it's still the best guide I've found to the rudiments of cybernetics
and the underlying logic of developing systems. Once we've laid down a stable platform of basic ideas we'll be equipped
to explore many directions of application, extension, and generalization.
As far as the future goes ...
The way I see it, scientific inquiry is a cybernetic process carried on at every scale from individual inquirers to
whole communities of inquiry. That's the way forward for me, at least, but it's still a ways to go.
