Finally, an honest analysis of the so-called "wonder language," Rust. There are plenty of memory-safe languages, starting with Java, which are far more developer-friendly and boast excellent ecosystems. For those who need to work close to hardware or the OS, C and C++ remain solid choices with robust ecosystems as well. Then there’s Rust—positioned somewhere in between. However, its complexity might hinder it from achieving widespread adoption, in my opinion.For memory safety, we already have tools like Valgrind, which can automatically detect many memory management and threading bugs, while also profiling programs in detail.So, do we really need Rust?
