This has been my experience also. Of course you can't forget the old stuff if you're maintaining an old codebase. But, I'm grateful to use lambdas, std algorithm, if constexpr, and fold expressions instead of boilerplate classes, bespoke loops, SFINAE hackery, and recursive variadic functions. There is less wizardry necessary than in the past.
