No, if can't be "like a UTM until ..." that just isn't like a UTM.
That is like saying you are just like an immortal being until you die,
thus you can call yourself immortal.
You don't understand what being something means.
Maybe that is why you have at various times claimed to be "like God"
because you don't understand what that means.
You are not immortal, but maybe immoral due to your past history that
has been revealed.
H is NOT a Halt Decider, because In computability theory, the halting
problem is the problem of determining, from a description of an
arbitrary computer program and an input, whether the program will finish
running, or continue to run forever.
Since D(D) has been shown to Halt, and you have even admittted that,
H(D,D) can NOT be a correct halt decider and say non-halting.
Either H isn't correct, or isn't a Halt Decider.
You claim that it is a correct halt decider is just proven to be a LIE
and shows that you are totally ignorant of the topic you are talking about.
