Rust has a nice up-to-date book and more rich community than C++. Plus better tooling.

I count the bank of existing knowledge, Stackoverflow posts and tutorials, as the community. In that case I don't see how such a new arrival could have a richer one than C++. There are still relevant C++ questions that someone asked on a forum in 2002.

Be careful. That can also be actively harmful as people copy paste years old code from stackoverflow and don't know that it is already doable via primitives language provide.

Example, all the answers that tell you to import jquery.

How do you suggest keeping up with all the primitives provided by C++? The language seems to have a major makeover every few years.

A new Standard is issued every third year. C++11 and C++20 had numerous big improvements that seriously improved the whole coding experience. C++14 and C++17 had few wholly new features, but relaxed many restrictions. C++23 will not be a big release, although probably it will get "reflection", making it easier to write and to use serializer/deserializer libraries, and a comprehensive networking library.

Most people pick up the new features a little at a time by reading blog posts or watching conference presentation videos. An hour or two a week, over as many weeks as you need, gets you up to speed fast enough.
