But note what those complexities buy you: they bring restrictions and limitations that allow you reason _more_ about the code.
This is in stark contrast to some other complex features that allow more stuff to happen with less code.
Rust is indeed, complex in the sense that it's features are non-trivial, but I find it less complex than C++ in the sense that it has 1) less surface syntax (because of lack of historical baggage) 2) more cohesive, principled feature set (again, hindsight is 20/20) 3) it's inherently more limiting, which helps reading, understanding and reasoning about code.
