Little fabbed players in semi selling off body parts to build new fabs to compete with huge self-funding players is unsustainable.

When in fact, the practice may lead to a sustainable state that is self-funding and requires no further spinoffs. Kind of like what you hope is going to happen to SGI in its own market... So you seem to be aware of the concept. fpg
