OK, I cannot be the only person looking at this who thinks, "OK, so if you have increased density with much lower power cost but higher chance of error, the answer is to use the long-understood techniques for correcting errors, which make a more complex circuit, but hey, you can find a point where you are still using much less power but are still so much faster".
What the hell is wrong with these reviewers, are they just afflicted with a desperate lack of imagination or are they really that ignorant? Or are they just terminally addicted to glib snarky put-downs?
