Given the state of the world it’s never going to happen but I honestly think that there should be an attempt at standardising plug sockets across the world. It is kind of ridiculous that that there are 15 different types of socket. What is anyone gaining from this madness?

A one-to-one mapping between standard plugs and standard wall power makes a lot of sense. But different standards of wall power should not share a single plug; that's just asking for trouble.

As for global standardization of wall power; maybe in an ideal world. But in reality, it would cost a ton (way more than merely replacing plugs and outlets) and doesn't seem worth it.

While entire countries will keep the imperial system versus the metric system, I'll never believe in global standardisation. Even if it's strictly better, there will always be a cost to changing, and therefore not everyone will agree.

I live in US and all SAE measurements are expressed in metric measurements. I am studying structural engineering.

Even 3/4 plywood is always 18mm, not 19.05mm.
