*You may not be proposing it but it's not realistic to propose nobody
anywhere will be dissatisfied with the pitifully small amount of energy
that a fusion reactor that can fit on a planet's surfers can produce, and
it's not realistic to propose that intelligent life is common but nobody
develops Nanotechnology even though it requires no breakthroughs in
physics, just improved engineering.  And once you have that, then just one
10^-12 gram self reproducing machine would be all you'd need to give your
solar system a Dyson sphere. But even our largest telescopes have seen no
signs of a Dyson Sphere, I maintain that the best explanation for that
observational fact is that we are alone in the observable universe.*
