Judging from this thread titled Your Age at SitePoint Forums, the web development and web design world is full of young talent. Patrick O'Keefe (iFroggy) is only 18 but runs a webhosting business, a webdesign business, and is webmaster of many popular communities. Marc James (mjames) is 17 and runs a successful sports-related site at Sports Central, among other achievements. Those are just 2 exemplary individuals who are young and are making successful web-related careers.
I wonder - are there and prodigies that are committers or project leads of Open Source projects like those under the Jakarta project umbrella?
