 Feedback Is  For  Making  The  Process A 
 Whole  Lot  More  Messy, To  Introduce A 
 Fractal  In The Spice  Mix... Things  Or 
 Populations  Of Things Start  To Be Self 
        Referential Or Self Eating        
 (AutoVore...) Or SpiralIng In  Or Out... 
                                          
 In  The Sixties They Did Research In The 
 Jungle  And  In The Sea  And They  Found 
 That Feedback Does Not Give Rise  To  An 
 Equilibrium. They  Were  Trying To Prove 
 That Nature  Is A Tame Beast.  But She'S 
                   Not!                   
 This May  Hold  True  Out  There...  But 
 Maybe Not  In Signal Wizardry? Depending
