Regarding George McKee's "picotechnology and positronic brains" article
in AIList V6 #47, my initial reaction was "You must be kidding, Mr. 
McKee!".  However, lest the non-physicist be misled:
      1) positronium ain't "small" but is the size of a hydrogen atom 
(which is essentially what it is).
      2) positronium decays rapidly, in less than a microsecond, be it 
ortho or para, ceramic matrix or not.  This fact was already well known 
at the time positronic brains came into the literature.
      3) a Cooper pair, as occurs in superconductors, is even much larger 
than positronium, since it is bound by exchange of phonons rather than 
photons.

What I don't know is whether Mr. McKee intended us to take his remarks 
about biology seriously.
