still, a jupiter brain is limited by his own definition of size... the size of a jovian like planet...
there is also problems arising of the locality of a such big density...
what to do to add more capacity ? when all is optimized, you probably
have to add matter to make grow the jovian computer... but assuming what
i know and except some speculative theories of using neutron stars to
make computers with really high ultra efficient density, there will be
an alt when the density is too high.
to stop the growing process is too bad...
small upload have the benefits to provide the cornucopia of a civilisation of minds, a jupiter brain with only one "identity" is really alone. i think one of the joys of existence reside in interractions between "peoples"
as far as i know, there is not enough matter available in our region of the universe to make a such rich civilisation (by interaction between differents entity)with jupiter brains only.
long distances are also a problems, with "liliputians", you could use all the matter available, not neccessary with apparition of density problems...
but my mind is not too clear about that now...
