Security is not the only dimension that matters, resource efficiency and scalability matter too. A big driver in the use of C++ is that it is more efficient than Python, Java, etc by an integer factor in real workloads. No one wants to increase data center sizes by 4x (or more) to run the same workload. Being that wasteful isn't environmentally friendly.
