When I was in grade school we had a school presentation when "Mr Science" had a show in the school auditorium. The LASER had just been invented, and he demonstrated a beam as it is always done, by illuminating a target and getting smoke to show the beam. They had to lower the lights for us to see it. He then went on to say it was invented, but as yet, no one had figured out a use for it. So it was just a curiosity. Now look around your house. I have several laser in my house in DVD recorders and players and so on. Life as we know it could not happen now without lasers and we can't imagine life without them. Just one of the millions of examples of inventions that changed the world.
