I think you do people a disservice. I'm not sure the video are supposed to do anything other than pass on information to viewers. Some of those viewers my use the information, some may pass it on to others, some may act on it to research further and many will do nothing but absorb the content and move on. Is there a problem with any of that? Is there a difference between this guy and a non-fiction author of a specific subject? We don't expect non-fiction author to revolutionise the lives of everyone that reads their book do we?
