A copy-paste response is worse than no rebuttal at all. That less-than-a-rebuttal means you accept that HHH(DD)==0 is wrong because DD halts when executed directly, as required to be a solution to the halting problem: (<X>,Y) maps to 1 if and only if X(Y) halts when executed directly (<X>,Y) maps to 0 if and only if X(Y) does not halt when executed directly
