"When you were a kid and the lights did not go on automatically when you came into a room, how did you find the little switch in the dark?"
The good news is this: as motion sensing technology improves, we can expect a few less fingerprints on the walls. Whether or not babies born in 2014 will be able to operate old-fashioned light switches in a 1960s historic home is anybody's guess, but hopefully the task will remain as natural as ... flipping a switch.
