It&#x27;s easy enough to change over -- just<p>1. Mandate that everyone in the country install universal (or dual-interface) plugs. Fairly low-cost, and pretty safe.<p>2. After 50 years, when all plug sockets will probably have been replaced, pick a plug standard and use that.<p>Like user pdpi, I&#x27;ve fallen in love with the UK sockets since moving here, with the Au&#x2F;NZ sockets coming in a distant second place. I&#x27;ve never had any trouble with either sort falling out of the socket, something I can&#x27;t say about the American or European standards.
