Moore's law should be respected, but we just can't have a limitless
supply of everything. There are tradeoffs to everything.

:-) Two minor points:
- It was 313 million per CUBIC millimeter, not square millimeter
- version 8 is already assigned, the next version would have to
be something like IPv10
Unless you want to give bacteria IP addresses, the only thing
I can think of is nanotechnology. Frankly, I don't think
nanomachines would have any need to communicate globally with
each other, but no harm in playing with the thought... :-)

Huh? We have been doing this since the dawn of IPv4! IPv6 changes
nothing in this respect.

No argument there. There are plenty of IPv6 addresses for all that.

While you're at it, mind giving me the scoop on the stock market?
Seriously, you're seeing the first section of an S curve. Exponential
growth doesn't go on forever. It tapers off when the environment is
saturated.
