I would think that not quoting Wikipedia articles in a conversation makes you an adult, but what do I know ...
I'm assuming you don't have any arguments left because you're needling me on my wikipedia link rather than addressing anything I actually said. If that's the case, you're really not adding anything constructive to this conversation.
Just because a technology is "cool" doesn't mean that you're acting like a high schooler for using it. Nor does using non-"cool" technology make you an adult.
