Therefore HHH should report on the actual input, the finite string that
describes a halting program. Not on the hypothetical input that does not
halt, because it is based on a hypothetical HHH that does not abort.
Why do you maintain that HHH should process the hypothetical input
instead of the actual input.
Do you really believe that 3+2 equals 5+3?
