There really are 10 types of people in the world. Some would argue that there are more, some would argue that there are less. Both are right. They are also both wrong. Perhaps there are only 10 types of people in the world. Whether that is correct or not depends on your point of view. ...

That is a lot of possible meanings, and there are quite a few more on the page. However, what I meant isn't even in that resource. A is the hexadecimal numeral that represents the number 10. Just a simple example of how much we don't know. In fact, in looking at the dictionary.com page I learned quite a bit I didn't know. I'd say, it's fair to assume that we don't know what people are "really" talking about most of the time. Perhaps we should check and make sure at the end of the conversation.
That really is the point of the article. There are lots of different ways to say one thing and one thing can say a lot of different things. So what are the 10 types of people in the world? Those who understand binary, and those who don't. Didn't you know that's what I was talking about?:p
