The cost of finding all the single-thread bottlenecks and parallelizing them is immense -- akin to the Manhattan Project -- and the payoff would be that Intel and AMD could sell different (perhaps lower power) processors than they do today. Why bother? We have processors that work perfectly well for desktop software.

True. At the same time, we keep expecting more from our machines, fuelling feature growth and consequential demand for faster processing mechanisms.

Yes, so future apps may prefer to run on the Larrabee cores, but the fat cores that old apps depend on cannot be removed.
