In fact, the number of C++ programmers is growing faster than ever. This is evident in the growing number and size of C++ conventions. (Bulgaria has its own, now.) Even ISO C++ Standard committee attendance is reliably a lot more than every previous meeting, even when held in inconvenient places. Attendance will hit 500 soon. The amount achieved at each meeting grows accordingly. Proposals get more scrutiny and draw on more experience.

To suggest C++ is a dying, slowing, or stagnant language is objectively delusional. The language is healthier than ever, and going gangbusters.
