I don't believe any hack of the 250+ presented was intended to be equally useful to 100% of the audience. The 9-year-old certainly didn't assume the audience was entirely children looking for playdates. Since the presentation obviously wasn't serious, imputing any serious 'assumptions' to the presenters is silly. It's not even an app, really. It's a 'Joke App Mockup' – a bit of trolling performance art. You give it more voice and power with your outrage.
