One thing that giant fires and big earthquakes were useful for was urban
renewal--looking at the Boston streets, one had to redo both the buildings
AND the streets at the time same, to change the geometry in the
city--otherwise, the buildings follow the streets, and the streets can't
move because there are buildings in the way. Until a disaster takes down a
large area, getting the property occupiers to all relinquisht their property
for razing and agreeing to eviction is extremely difficult.
Yes, different gauges of rails exist, but -conservatism- in design means
that as with city street which get set and follow paths trod centuries
earlier, the path of, er, least resistance, is to repeat what's been done
before... just look at the Internet protocols, which lack error detection
and forward error correction in the encoding--things which have been part of
the technical knowledge base since the 1970s but are NOT used on the
Internet as transmission protocol for data packets intrinisically--and lack
encoding to make it less trivial for spammers and computer infection
spreaders and and identity spoofer and data thieves etc., to pursue their
noxious pastimes... because the ARPAnet was a lab experiment that
was -there- and never got shutdown, it got glommed onto and -grew-... it's
an escaped lab experiment never intended to be the basis for commercial
anything, it was a LAB EXPERIMENT, one that got -loose- and makes kudzu look
contained. There are lots better ways of encoding data for transmission
delivery than TCP/IP, but TCP/IP is what got -in- and took over.... sigh.
