For me, performance is much more critical, and the languages with ownership semantics do not easily allow me to get those performance benefits unless I ignore/bypass the ownership semantics of the language. It's one of the reasons I started my own language, the Odin programming language. I wanted the ability to have control over memory layout and memory allocations, and be tied to a specific model of how structure and design my program determined by the programming language itself, especially ideas which have yet to prove themselves as being "good" (by whatever metric).
