Yep, exactly this. It was only 8 years ago, but its several generations of changes for C++. As you said, it was very unfortunate timing, but not much I can do except pick up a book and start learning. But I'd probably dedicate that energy to delving deeper into Python, Go or even Java at this point. Sad to see decades of work no longer relevant, but it got me to where I am today, so it was worth something I suppose.
