But screen sizes are still expressed in inches
Also, the (I think it's use is widespread enough to call it international at least) measurement of time uses ridiculously complicated units that don't really have a point anymore, except the day and the year that is. Months and weeks are a complete mess. And the day/hour/minute/second conversion could be much simplier.
What kind of dumbass school doesn't teach script? Or is it only in the "special" classrooms that they don't teach it?
Well the problem with cursive writing is that most people will use it more during their education than during the rest of their life, because either they don't need to write, either they use a computer to do it. But learning cursive writing is done very early so I don't think dropping it can really save a lot of time.
