It is 2020. You are looking at a series of projects your company has teed up. All are greenfield efforts - no legacy. What would be the attributes of a project that would have you recommend C as the programming language?
For anything embedded you have practically no choice but to use C (or assembly). Same goes for a lot of systems programming, e.g. writing Linux drivers.
Anything high performance: game engine, scientific computation, deep packet inspection, image analysis, machine learning, rendering engines, high frequency trading.... The list is long!
