Moore's law is not compute power (mips, flops, stones, watts,
whatever), it's number of transistors in an "IC". And while an "IC"
could be 10sq-cm or more, in reality Moore's refers to feature size.
And now that research is bumping against wall of physics,
Moore's is known to be a dead roadmap. Stacking is not
breaking those physics.

Btw, today's cpu's have ~50B transistors,
plugged into a NIC with maybe ~1B,
plenty enough for a magic packet to
exfiltrate secret keys from core, etc.
And they've already designed in enough convenient "bugs"
to make all multiuser shared computing platforms
(Amazon, Microsoft, Google, webhosting, etc) nothing
but exploitable swiss cheese.
