These days, there's a connector for almost everything: if it's not MagSafe 2 it's that weird USB connector or RCA or who knows what else. Wouldn't it be amazing if there was a single converter box to interconnect them all?
That's exactly what Randall Munroe has imagines in today's XKCD. It is something to dream for. (Not pictured, the "50-lb sack of gender changers, and also an add-on device with a voltage selector and a zillion circular center pin DC adapter tips so you can power any of those devices from the 90s.")
