- Historical accident, mostly. As others have pointed out, there are other
- voltages in use too. The higher voltages have both advantages and
- disadvantages, and electrical power systems evolved in parallel so there
- wasn't a single pioneer that everyone else followed.

- Not a prayer. The costs of switching would be astronomical, all the more
- so because you can't convert one appliance at a time. The benefits don't
- justify the pain.
