I've had the same experience. Hadn't really touched C++ since the late 90's and had traumatic memories from those times but working in my own C++11 codebase recently has been both pleasant and surprisingly productive. The language is headed in the right direction but it's a big ship to steer.
I'm pretty glad we use C++ in enterprise development (and extra glad we use C++11) ;) There are barely any other languages which can replace it yet. Rust is a good candidate.
You're lucky to be able to use such a recent standard in enterprise dev. Those shops tend to be pretty conservative in my experience. Where do you work?
It happened fairly recently, after the switch to the newest gcc, because we basically decoupled the compiler from the underlying distro (using cross compilation), so compiler could be updated independently. For a long time we were stuck with an old gcc.
