Made a list of all the revision control tools I've used over the decades, the year they were created, and the year I last used them:

    sccs            1973    2000
    rcs             1982    2000
    cvs             1990    2004
    clearcase       1992    2004
    perforce        1995    2011
    subversion      2000    2015
    mercurial       2005    2015
    git             2005    present

So, at least for me, they last around 15 years or so.

But often time when I tell juinors that when they're my age, git will be distant a strange memory to them, they look at me funny. It's a wonderful tool and earned its success, but I'll be sad if it's our final take on the problem.
