C 1972, C++ 1985, Erlang 1986, Perl 1988, Python 1991, JavaScript 1995. C is half-way to 100: an amazing fact in the rapidly-changing world of technology. Of all these, Perl seems to have suffered the biggest loss of popularity so far, while Erlang has the least popularity to lose. I'd be somewhat surprised if any of these are still in common use in 2072, but OTOH, I'd also be surprised if any of them were completely unused, with the possible exception of Perl.
