> Sometimes I read about the rapidly evolving modern C++ and I wonder if they are moving too fast

Sure there are a lot of small accumulating changes, but they can easily be caught up on by reading the documentation when you actually need those features.

On the other hand, I've been waiting for modules, concepts and networking literally since 2012 - and I only started using C++ in 2011, with around 2 years of experience in C. I don't think anyone is moving too fast in that direction.

Edit: I still remember the graphic from the committee/Herb, which showed 2014 for the networking TS, and 2017 for concepts/modules. The "networking TS" then ended up being like one .pdf file with functions for LE/BE conversion, and well obviously concepts and modules aren't in C++17. (Neither is any actual networking.) And while concepts look to be on a fairly good path for C++20, I'm going to be very surprised (and happy) if they'd manage to get modules in, too.
