How Worried Are You By The Symbol Grounding Problem?

Imagine you're a mental representation. You are a computational symbol system, and your job is to contain knowledge that is about the world and that can help your organism interact with that world (Newell, 1980). The 'aboutness' thing is the most important part of you - you are an intentional system, which means you have content that is meaningful.

So where did your content come from? (I'd like to know your thoughts, so please help by answering the questions at the end!)
