As an (ex-)C++ developer, this is mainly my feeling too. Rust solves many problems in a very elegant way, but those problems are things that most experienced/skilled C++ developers solved by sticking to a fixed set of best practices, mostly avoiding these problems.

Most C++ developers I talk to about Rust express the same sentiment, they usually like the idea, but aren't personally interested in learning it because it solves problems they're rarely confronted with.

I tried picking up Rust a few times since it does interest me, and I like trying and learning new things, but I currently don't have the time to really dive into it. Go on the other hand took no time at all to get into, and was promoted pretty quickly into one of the more frequently used tools in my toolbox, just like Python.
