I'm saying that negentropy is the *limiting* constraint - not energy, 
not space, not even cooling area.  The limiting constraint is what you 
have least of, relative to your other resources, and what you cannot 
easily make more of.  The total amount you can compute in this universe 
before you die or find a way to leave, is determined by limits on 
negentropy - not space, not cooling, not even time.
