Finance is one area where C++ still rules as full stack language.
In the typical enterprise, whose domain isn't selling software products, C++ tends to be mostly used as infrastructure language for .NET/Java/JS native libraries or interacting with their runtime APIs.
I work in the games industry and C++ is used for almost all system code (not tools) but this still feels like Shigeru Miyamoto taking a gig at a toy shop or Spielberg working at Universal Studios amusement park.
You know, Google seems to attract a lot influential technologists that don't necessarily have a role in their organization. I guess it makes sense that other companies do this as well.
