I'm not seeing that in real-world projects though, and it's not only about performance. These are just two random examples from my own experience of where high-level language features get in the way (I guess the TL;DR is: yes, it's possible to write high-performance software in high-level languages, but it's often more effort, and may require to write unreadble and "non-idiomatic" code, because you need to "appease" the compiler much more than in a lower level language):

Also let's not forget about build times.
