Other countries around the world have wasted billions and trillions on a lot of things (senseless wars, for starters) and gotten through the short-term pain that this has caused - that doesn't mean it was a good idea.

If nothing else, the $N billion of nationwide switching costs could have been used on, like, renewable power, or something.

It sounds as if you really think it's a good idea to stick with imperial. In your opinion is this a common attitude within the technologically sophisticated section of US society? I didn't think it was but maybe I am mistaken.

I prefer metric, from a policy perspective, I just think the path dependence has too strong a case to revamp industrial toolchains. (Changing the road signs and temperatures, by contrast, is both trivial and useless.)

Other things which are better that we'll probably never have include broader gauge railways, Dvorak for everyone, Wankel engines, and Betamax (vs VHS).
