   The actual issue is the NO ONE here (or perhaps anywhere)   
   sufficiently understands the key details about   
   COMPUTING THE MAPPING FROM AN INPUT TO AN OUTPUT.   
      
   Many here know that a mapping from the input must be   
   computed. What they don't know are ALL of the tiny   
   detailed steps required to compute this mapping.   
      
   They simply guess that because DD(DD) halts that   
   DD correctly simulated by HHH must also halt.   
      
   They cannot provide these detailed steps of the   
   execution trace of each machine instruction showing   
   exactly how DD correctly emulated by HHH halts   
   BECAUSE THEY KNOW THAT THEY ARE WRONG AND ONLY PLAYING HEAD GAMES.
