Imagine an old star that is undergoing a collapse - the matter infalls under it's own gravity, accelerating faster and faster. At some point, the matter runs out of density - the neutrons slam into each other and the whole mass of the star going inwards at a good fraction of c tries to undergo an abrupt stop.
The leisurely free fall turns into the violence of inertia. Then, either that violence is enough, and the collapse continues towards a black hole, or it's not enough, and all we get is a boring neutron star.
Will the economical inertia behind the Moore’s Law push it past each technology's clang of limits all the way towards some sort of singularity, or will it one day come to an abrupt halt against an immovable wall of the structure of the universe?
The latter, obviously.
Would that wall be CMOS? We can't really know until we hit it.
