So do I. I just think that it will be nice should there come a day where knowing git will allow you to deal with the majority of the positions out there. I do not believe git is a 100% fit for all organizations. I do, however, believe git is flexible enough to be a fit for, say, 80-90% of them.

I think git will become a de facto standard. Like all such things, though, there will be alternatives available and in active use.
