I think the news is less "13 year old revolutionized medicine" and more "13 year old used ingenuity to create cool thing". Or at least, that's how I think it should be read. Focusing too much on the end result is likely not the best outcome because, while its a working prototype, many interesting prototypes never make it to fully end user capable system and there are a lot of hurdles to overcome to get it there.
But that doesn't take away from the fact that its a cool project and the kid did a great job in coming up with it and executing on it! Its definitely far beyond what most people achieve, nevermind 13 year olds.
This is a story about inspiration and achievement. Objective facts are less important than the message, IMO, especially after decades of "try-hard" being ridiculed in the U.S.
