Nobody's talking about the real casualty of this shift. What's going to happen to all the jokes about "how many (insert category of person here) does it take to change a light bulb?" now that people don't have to regularly change light bulbs anymore?
Or the old riddle of having to match 3 lights to 3 switches with only one guess, since the solution relied on the bulb getting hot and LEDs barely get warm.
Wait what is this riddle
“A windowless room contains three identical light fixtures, each containing an identical light bulb or light globe. Each light is connected to one of three switches outside of the room. Each bulb is switched off at present. You are outside the room, and the door is closed. Before opening the door you may play around with the light switches as many times as you like. But once you've opened the door, you may no longer touch a switch. After this, you go into the room and examine the lights. How can you tell which switch goes to which light?”
The solution is:
Now, when you enter the room, you’ll have one lit bulb, one warm unlit bulb, and one cold unlit bulb, letting you solve the riddle.
