This is a somewhat uninspiring attitude. There was nothing wrong with the PS/2 mouse and keyboard plugs either, nor the 25-pin printer plugs, nor some barrel plug for charging phones. But the problem is there were so many different things that all needed their own plug. Now there's no mouse plug or phone plug or printer plug since they all use USB. Laptops with a standard non-USB plug will still add to the duplication and inconvenience just like those old keyboards did. You won't be able to charge your phone with your standard barrel plug laptop charger, so you'll still have to carry two adapters when you travel.
