Is it ?

C++ is definitely not dying.

Here are some reasons:

Most high-level languages decide the format of your data for you. This is good for most things, but if a large part of your application needs specific data layouts, then you are out of luck.
Most high-level languages can not support multiple forms of data allocations. Some applications need a range of allocation strategies, ranging from completely automatic (garbage collection) to completely manual.
Most high-level environments do not allow for fine-grained control of computing resources, e.g. soft real-time guarantees.
Most high-level languages do not allow for C/C++ intrinsics, for instance leveraging access to the SSE registers.
Most high-level languages do not allow for fine-grained control, for instance allowing different forms of threading mechanisms.

Of course, you can always say that you can use the foreign function interface, but then you lose inlining and speed. More importantly, you end up with a project with several different languages. That is generally a very bad idea.

In short, most high-level languages will remain used for only for toys and applications where speed and resource constraints is of no concern. Which is sad, because C++ has many, many problems - the most major one being that it is so easy to produce bugs.

Thanks,
