Firstly, I believe everyone's intelligent, just in varying degrees. One of the biggest insults you can inflict on others is calling them stupid. Many people take that to heart.

But to answer your question: you typically change your language depending on who you're talking to, to cater to their level of understanding and background knowledge about a subject.

You don't hear me talking about coding to my mother, since she can barely use an iPad. She knows that code is used to make her apps, but that's it. You can't go into high level detail like APIs and encryption, sandboxing, etc with her.
