This is a great point and can't be understated. When you're in a meeting or conversing with someone who just knows things, the conversation moves so very much faster than if you have to guess or be vague due to a lack of knowledge. I Google like crazy for answers about things, but I consider not knowing a failure on my part, and endeavor to learn the thing I had to google, so I don't have to "fail" again. I think everyone should think of this problem in a similar way, lest we fall into a habit of saying whatever we want and assuming we'll be corrected if we're wrong (or some other ill).
