At the same time modernization is necessary, it's not looking at
yesterday's lessons, it's what you learn from them.
Ever-larger open hearth furnaces (because that worked before) and punting
on the Linz-Donowitz process because you tried once and lost a bunch of
money is learning from the past, but it means you build the Fairless works
new from the ground up post-war and it's effectively gone before the turn
of the century.

There are basic things you need to pay attention to. A PCC can run on
salty streets for years and if you take care of it, it runs... for years.
Bus frames, on the other hand, apparently rot out, because the lightweight
tubular fuel-saving (you're not hauling around a big heavy chassis) design
needs to have something applied to it to make it not rust, or you need to
clean it too often (see "Neoplan") for american transit systems.
Modern is important, but it isn't always better. If you ignore it though,
that's no good either.

Imagine what happened if you invented a state of the art operating system
and it lost your files while making a blue screen with white gibberish
appear periodically.
