I have founded it important mostly as a confidence builder. To use and program a computer without having at least seen how it all works at a lower level felt wrong to me. I felt like I had no foundation to really understand what I was doing. I'm not claiming that I know which opcodes are being executed as I run my django dev server - that's not the point. But it's about having a clue. Some day, if I have to dig down that deeply into my machine, I will not fear. I have seen what it looks like down there and I know which tools to bring with me.
