The prospect of fusion power is as old as the H-bomb.  We all rejoice that the hydrogen bomb has never been used in warfare, but its swords-into-plowshares brother has not yet produced a watt of power.  Laser fusion is as complex as it comes.  It makes uranium fuel reactors look simple by comparison.  It is remarkable that the technology is now poised (maybe) at the point of making more power than it consumes.  The preparation of the fuel is complex, the lasers are very fragile, and the idea of replicating one of these beasts for commercial power production is just crazy.  The design is too complex!  By comparison, a wind turbine is a motor with a blade on it!  I am sure that there are people sitting around wondering, "how are we going to top the large hadron collider?"  The answer: you're not.  We have to face the fact that there are limits to technical complexity that can be supported even when there is global participation.  I'm no Luddite, but we don't get extra credit by making the solution to a problem extra complex.
