Someone made a case a few years ago that bleeding edge works only for
CPUs, because they will sell even at a high price, and memory, because
you can make a lot of chips of really small size.

I won't try to recreate the arguments, but they seemed valid.

Perhaps this was true in the ancient times. Have you noticed the
profit on commodity DRAM lately? ...I rest my case!
