 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 
 On  Your  Technique,  You  Might  Easily
