Some TV shows might be more worthwhile than building an Eiffel tower out of match sticks.
It's too bad the guy did the illumination with LEDs, instead of using matches for that, too. (Although that would have worked only once.)
Building something, even an Eiffel tower out of match sticks, is accomplishing something. How valuable or useful that something is is debatable, and there are probably better things to build then a match-stick tower, but it is still an accomplishment it adds to the world in a way that watching TV never will.
I will admit to watching TV and enjoying it, but I consider it an indulgence. I always have something better to do, and I think that is true of nearly everyone.
But of course watching something can "accomplish something" -- it can broaden your experience of reality by showing you something that took place on the other side of the world, or ten years ago.
The best television shows you moments of life that otherwise only the people who were actually present might have had a chance to see.
