> You really need extremely smart smart data structures and organisation and very smart algorithms to manage the concurrency. C is a language where you have all that freedom to do whatever you want leading to high performance and low latency. But it leaves that work to the developer, thousands of hours of testing and reviewing to ensure no little corner case is missed. I think the argument that unsafe is used making the language have “holes” is somewhat misdirected. When I see a rust implementation of a doubly linked list with unsafe I know exactly where I’m on my own (a few lines) and where the compiler does the job for me (the rest of it). It’s not as if that means safety or flexibility is out the window. It means “do the manual safety review on these two lines”.
