Global unit system prospect is looking good for the long term I think, we only have a handful of them, if only the US could get its game together on this one it'd be a done deal… We still have way too many electrical plugs plus combos for voltage/frequency, also a pain. Just had to buy a new hair clipper this morning because my European one didn't like the US mains. It seems the stuff that involves direct human interactions is the worst, like having around two hundred different currencies. This one is fairly stupid in hindsight, since there is very little cultural value there. But language, the one thing that we use the most to interact with one another, tops everything with thousands of non-compatible variations… sigh.
