Why two-pins, and three pins, of various shapes, why can't they all just be three-pins, so we don't have to keep looking for adapters...?

It has to do with the country you are in, and what the electrical system governing body has set for standards as electrical power has developed over the years. As we all know how hard it is for different countries to agree to do something the same way, what is surprising is that there are only 17 types of outlets, two frequencies (50 & 60hz), and 9 voltages (100, 110, 115, 120, 127, 220, 230, 240, 250)
As for why we don't all use the same plug, who's do we adopt?
Most of the electronics is designed in Japan, but built in China. So wich standard would you be willing to change all your wiring in your home and office to?
The cleverest idea was, in my opinion, the development of the IEC60320 Appliance coupler (this is the connector found on the back of most computers and test equipment, as well as some home entertainment). This is a standardized 3 pin inlet that allows the manufacture to build a piece of equipment he can ship anywere, and the end user can purchase a linecord locally that fits his own outlets.

every country uses different default electric current and voltage units. so there are various pins like 2-3 pins in a plug and they vary upon the default electric current in any country.

different countries have different plugs. The plugs also depend on the amount of current being used. Different country has different voltage supplied to the house.
