Do most bitcoin users actually think that bitcoin is going to 'replace other currency, ATMs on every street corner', etc. at some point in the future? Is such a future actually necessary for bitcoin's continued success or maintainance?

I personally think that such a view is not realistic, but I like bitcoin because I believe in the concept, so I will continue to use bitcoin on some occasions. Is the view I mentioned the general consensus of users that use bitcoin, or just the opinion on a few of what COULD happen? Just want to know people's thoughts..
