Some more extracts from reports: Imagine if POET should succeed

The problem with GaAs, InGaAs, carbon nanotubes, graphene, and any number of exotic materials that we cover on ExtremeTech, is that they’re trying to replace the most advanced technology in the world. It is not hyperbolic to state that hundreds of billions of dollars have been poured into CMOS R&D; maybe trillions. For these silicon replacements to even stand a chance, a similar investment will need to be made — and put simply, there is probably only one group in the world who has the requisite time or resources: Intel. We don’t even have definitive proof that the new materials will scale much further than silicon — so we’d be plowing billions of dollars into something that might only get us another few years of Moore’s law.
