Erm, yeah. Thanks for calling me on that -- I horribly condensed what I
was trying to say.

By the original definition (number of transistors per square inch doubles
every year), it has slowed to every 2.5 years. See the graph I linked to.

Data density is currently doubling every 18 months, and holding steady at
that rate.

(But this *is* off topic for NANOG...)
