The idea being that consumer items will, more and more, be able to take DC directly instead of expecting AC.

For example, any device that takes in USB power with a 120VAC "wall wart" plug can just be used with a buck convert plug instead or being powered directly from the DC current.

LED lighting is taking in AC then converting to DC to power the LEDs. Your phone is taking in AC then converting to DC to power it. Your laptop is taking in AC then converting to DC to power it.

There are some household machines which will require some heavy duty power draw but much of the consumer products we use is powered off of DC to begin with. Powering directly off of DC would be cutting out the "middle man" of AC.

Yes, it causes issues today. But tomorrow, I'm expecting that the transformer will be outside the device (as now with wall warts and most laptops) rather than inside (as with your TV). And that minority who are handy enough with tools can patch past the internal transformer with a soldering iron and a screwdriver in the meantime.
