I am more optimistic now than before, because I've been reading more history and a lot of my optimism comes from history. So in general just to answer yes I am more optimistic than ever. And I think I stand behind most of the sentiments in the inevitable. We have a incredible choice about the character of this these ais and who owns them and how they're regulated and stuff but the inevitable is that they're going to be coming that they's going to be there.
