With the admission that I will be one of these people in less than 4 years isn't thirty a little old to be watching cartoons.
Why should it be? Isn't the whole point of being an adult that you're free to watch, read, or listen to whatever you want? If you still like cartoons, why the heck should you stop watching them?
There's no reason to assume that cartoons are automatically meant for children. That's a stereotype. Animation is a medium, not a genre. And even if we are talking specifically about shows made to be suitable for children, it's a myth that such shows are unsuitable for adults. Some of them are, the weaker and dumber stuff. But there's plenty of weak and dumb stuff aimed at adults too. Besides, don't our children deserve the highest quality of material that we're capable of giving them? And isn't quality storytelling worth watching no matter your age? Good children's stories are good stories, period. An episode of
Avatar: The Last Airbender or
The Spectacular Spider-Man is a thousand times smarter and more sophisticated than any of the dozens of sleazy, cheap, mindless reality shows that have the gall to call themselves "adult" programming.
Not to mention that most people who make children's programming are making it for themselves too, so that the experience will be enjoyable for them. Also they're making it for the parents who will ideally be watching along with their children.
P.S. I do realize there is a defference between animated shoes and cartoons....
No, there isn't. A cartoon is a representational drawing. An animated cartoon is a series of such drawings simulating movement. The difference between "cartoon" and "animated show" is like the difference between "comic book" and "graphic novel" or "stewardess" and "flight attendant." They mean exactly the same thing, but one is an attempt to avoid the perceived stigma attached to the other.
