Olcott could as well challenge everyone to draw a correct square circle.

No one will attempt to draw a square circle. Does that imply that it is 
wrong to say that another failed attempt to draw a square circle is 
incorrect?

Similarly, HHH cannot possibly simulate itself correctly. Olcott's HHH 
is incorrect, but a correct HHH that simulates itself does not exist. 
Therefore, it is very stupid to challenge everyone to correct HHH.
