Heh - I was just being flippant, but I didn't know that about Boeing. Apparently it's controversial: http://metricviews.org.uk/2007/11/boeing787-grounded/

When to accept change and when to dig in - always a challenge. Dash vs. Darkcoin - the trolls had a field day with that one - I remember "sounds like a laundry detergent", as though that were a terrible thing.

Living in Canada, I got used to metric a few decades back (Trudeau the elder) but some people never made the change and probably paid a price in job opportunities, peace of mind, and so forth. They will die off in time and those going through K-12 here will know only metric as normal.

Patterns, patterns, patterns. History doesn't repeat itself, but it rhymes. Now about that credit market system.
