Another ietf idea that makes me crazy is the motto of "no host

Dumb endpoints is a huge change from the design of the internet (and
ARPAnet), with a dumb middle and smart ends: I suspect the original
commentator was talking about mere /relative/ dumbness...
This isn't a resource problem, it's a code problem. The IETF wants
10-15 year old hosts to be able to connect to a network and perform
basic networking. It might not be very optimized, but the basic
function should be there. New functionality can optimize for different
factors, but making older host stop working is frowned upon.
Fortunately this is a solved problem in capacity planning: you replace
machines often enough that they're not constantly out of service being
repaired. 10 to 15 human-years is the equivalent of 70 to 105 of the
dog-years we use in this silly business (;-))
The oldest machine I use is a dps8-m, and I'll be slightly amazed if we
can provide native TCP. Right now I ssh into the virtual machine that's
running it, all so I can continue to fiddle around with Multics.
