For the last few years, I’ve been developing CAM/CAE software on my job, sometimes embedded Linux.

Same experience: last time I developed software written entirely in C++ was in 2008. Nowadays, only using C++ for DLLs consumed by C#, for 2 reasons: manually vectorized SIMD for CPU bound numerical stuff, and consuming C or C++ libraries like GPU APIs, MS Media Foundation, or Eigen.
