The other idea that I'd had, with having sensors like this attached to 
the internet, was an early warning system that's cheap to deploy 
everywhere and effective.

I'd asked myself this question, back in march.

"How THE HELL - in 1967 - do you design something so good, that: after 
lasting 10 years beyond your intended design life - can also withstand a 
quake 7x the size of what you designed it for? Followed by a tsunami? 
Whose hand can I shake? Who gets a medal? Are any of those engineers 
from the 60s still alive? I mean, WOW. They did that design, at least in 
part, with /slide rules/."
