As a consumer, I'd rather see them make faster hard drives. I think that's a much bigger impact than faster CPUs. I remember when i got my mac book pro 2015. the hard drive was so much faster than 5 years earlier. I can now boot up in less than 20 seconds. and my IDE opens in less then 4 seconds. getting those two numbers down to 1 or less would be a much bigger improvement, IMHO.
They're correct, it's been obvious to everyone that there are limits to physics that preclude pushing much smaller than we are presently designing without switching to a different method of creating logic devices.
