Hopefully one day we'll have a grid designed to carry high voltages over long distances instead of using inefficient low voltage transmission which exposes the grid to these dangers.
Is this supposed to be sarcastic? The grid does carry high voltages over long distances. The standard voltage in North America is 765kV, and for HVDC lines it can be 2MV. But that's for long-distance transmission lines, not more local distribution lines, which are necessarily lower voltage (36kV I think) for practical and safety reasons.
