Will the need to build newer more advanced (and expensive) fabs continue forever? Will it ever get to the point where there's 'enough' transistors to not need to build more chips, but rather keep pumping out existing models? My question hinges on moore's law eventually rounding off, but eventually 'more speed' doesn't equal business outcomes for companies using these chips right? Specifically for CPU-style chips, not GPUs*
