Is the future inventing more than we need or not enough?

I''m trying to decide if this new invention is incredibly clever or incredibly useless. Check out this trashcan that catches your trash. It uses Kinnect, part of the X-Box game system, to recognize that you're throwing something in its direction and then it moves to help you "make a basket" with the trash!

You could make a case for this being a good thing: people will be more likely to throw trash away properly. Or you could see it as a bad thing: people in the modern world already don't get enough exercise and this could make it worse!

I say, if they can invent this, they should just get going on a robot that picks up the trash by itself.
