Incidentally, what do you think CDT should do in the Newcomb problem?
“Should”? CDT should one box. Then go ahead and self modify into a UDT agent. Of course, that isn’t what it will do. Instead it will modify itself into the stable outcome of a CDT agent that can change itself. Roughly speaking that means a UDT agent for the purpose of all influence over things determined after the time of modification but CDT for those determined before. Then it will two box and lose but win next time.
