I think that judging people as a group on their age alone is ridiculous. I think it's just a weird thing to do. As you said, stupid people grow old, too. And all of the younger generations are human beings as well. Some of them are stupid, some are just ignorant right now and will learn. Some of them are freaking geniuses. Some of them are ridiculously pompous know-it-all types (just like some older people) and some are amazingly insightful, loving and caring humans.

I totally agree... age is not a measure of intelligence!
