>> Obviously, the people running ITER don't think that it can be done cheaper That's actually not obvious at all. ITER project was started 12 years ago. By now it's very likely that there are ways to do it cheaper. But what do you do? Abandon the partially built ITER and start over? And what do you do if 5 years from now there are ways to build it cheaper still? So the government bureaucracies are marching on to complete it, which IMO is a sensible thing to do. But it doesn't mean it can't be done cheaper or more simply with 2020 technology.
