Nice. And of course we can solve overpopulation and the Halting
Problem the same way...

Yes. They are always the hard part when solving problems with
imaginary technology :-) That is why I really admire Dyson for
actually calculating how to move stars and galactic masses using known
physics, instead of imaginary physics. I think we need more of that on
this list.
