Rust is design by committee with complicated and large syntax area and to solve one problem of memory safety created a mountain of borrow checker syntax and a steep learning curve.

So only time will tell if BDFL based language comes up like Linux or design by committee like language. Right now Rust is not that significant like Nim and Zig so all have a chance to come up.

Once there are substantial software written in them like C or C++ than only will know, right now among modern language only golang and Swift reached that stages as being significant systems programming language in spite of GC. Indeed I doubt if Rust will be as revolutionary as Lisp or Haskell or Smalltalk in terms of contributions for the development of compilers and language designs.
