 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

 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
