2020 life with magic pencils & robot chefs, 85,000 children submitted ideas

There's something that really bothers me about this:

"The best of the ideas will be buried in a time capsule, to be opened in 2020."

Who decides which ones are the best? Adults. So why have children draw them at all? Don't go to children for their childlike viewpoint if you're just going to filter it through your adult viewpoint.
