It'll have a hard time in systems programming too, at least as far as converting people from C/C++.
It will attract new talent, but it's obvious to me that people who have invested years in C or C++ will not jump to Rust. The reasons for that are numerous, but the most important one to me is that in many cases __it is a lot harder in terms of mental load and time required to write safe Rust code than it is to write the equivalent C/C++__.
Not to mention a complicated syntax and flow that turns your brain into mush. Imagine working with code that looks like this all day (1).
Extrapolating from that we can probably say that Rust will be a failure (assuming goal of making a dent in the C/C++ entrenchment) in the near/medium term.
