 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
