We have hybrid systems which can render about a day's worth of dynamics 
in a second. But they're not all-purpose, so you need exascale systems to
figure out how to build dedicated hardware, which can't be modifed after
the fact, only adjusted in some operational parameters.

Bootstrap stages are sacrificial/discardable, just as in compiler bootstrap.
