ELI5: Why are power points (sockets, outlets) different around the world?

I have to travel with a whole bunch of adapters and my hairdryer/phone charger nearly died last trip.  Was this a big lapse in planning when electricity came about?

Because different engineers thouht that different things would be important for a socket, e.g. ability to transfer a lot of current vs. small size and simple (=cheap) construction.

People did not have much electrical appliances back then, and they certainly did not travel a lot with them. So for fairly a long time people would use electricity for light, and to power devices which were too big to carry around. This became a big deal when people had radios or electrical razors (or later: computers) which were small enough to take with them.
