C++ is changing way too fast to be useful anymore. I spent the first 15 years of my life loving C++ but in the last 8 years or so, the C++ committee has vastly outpaced its supply lines. I've been out of the language since then and I might as well learn a new language rather than try to re-understand the differences between C++ back then and now.

The only people that can keep up are the hobbyists and the language purists. It's become a circle jerk and that's a shame because they are modernizing themselves out of existence, in my opinion. No one in real software can keep up with the biannual changes and it's getting to the point where migrating to another language like Go or Java is a lot more stable and less risky.
