No more 1000 cores on a chip for you

Really? No more exponential growth on performance forever? You mean, no more exponential growth forever such as that of real estate, or the Dow Jones in 2008, or Nasdaq as in 2001? Apparently yes: too many cores and the memory subsystem cannot deal with the enormous load, which in turn leads to poor performance.

How many is too many? Anything past about 8.

What to say... I am not surprised. Interestingly, however, message passing is seen as useful in this context.

Everything has a price

People with lots of money invested money with Madoff, because since they had a lot of money then clearly they needed >10% yearly returns no matter what. Therefore, people that buy a painkiller at a higher price enjoy better results than when buying the same thing at a discount.

Of course the painkiller was a placebo to begin with.

Makes perfect sense to me.
