But then the claim is meaningless.
If you can't show me why it's fun, or why it's relevant in some other way, then I'm out. (And you don't have very long to do it, either...)
[Edit to reply to tikhonj, because I'm rate limited: The "value proposition" is what makes it valuable to the listener. Why should they give you their attention and time? Value is "anything that makes people interested in what you're telling them", as opposed to all the things that don't make them interested. Since the "don't make them interested" set is not empty (far from it!), then no, it's not a tautology.]
So describing a fun problem is implicitly telling the audience why they should listen.
