To quote Yogi Berra, "it's déjà vu all over again."
Those of us of a certain vintage remember this precise issue with Fortran a couple decades ago, and those out there of a certain further vintage probably remember it with COBOL. So on and so forth back through PL/I, Algol, and so on to the dawn of time.
While there have certainly been consequences of the dearth of COBOL and Fortran devs, ultimately the world has thus far survived. We'll survive the obsolescence of C++ (if indeed that's what this is).
