> It's not just "I don't know" that is important, but also the next part of the thought: "but I can find out." This isn't about asking someone else to find out how to do it, this is about solving a problem, which may no solution. So saying, "but I can find out" it is comically ridiculous. Consider this, how are you going to solve the traveling salesman problem, for 10,000 nodes on your iPhone in 5 seconds? I don't know, but I can find out.
