Now assume that Moore's law stays healthy and in a few decades we're carrying around dojo-equivalent smart phones. Or implants. What do our apps do with all that compute? Detailed convincing AR, accurate real-time translation, identify almost any object in sight, turing-test passing answering machine. We'll be carrying around neural-net training hardware that is different than the stuff between our ears, often worse…

Performance per watt is not improving that much, nor is feature size. You'll probably never be carrying around a supercomputer with this many FLOPS.

Even with reversible computing?

Earlier quoted context omitted.

Moore’s law is quite dead. Transistor density isn’t doubling. We’re still getting speed increases due to architectural improvements, but transistor density is capping out because thermals are a problem. That’s why you see these massive wafer designs and they’re not shrinking.

Raw transistor count isn't the same as density.

Both TSMC and Intel have transistor density increases on their process roadmaps, although they definitely aren't doubling.

Insane, truly insane. Meanwhile laptop CPUs, with the notable exception of M1, are impossible to cool.

Not sure that's relevant here - the reason they can cool this is because they're custom-designing housing, server racks, etc for these chips based on the amount of power they draw. You could cool pretty much anything if you were able to give it this much love and care.

I wish I had your optimism. All I expect are better ways to deliver targeted advertising.

Moore’s law was about count, not density.

What about cloud services. A 5G connection to a supercomputer on demand.
