My feeling is that modern C++ generally makes things simpler once you know and understand the new features (a large part of why I like it). In most cases they are either as performant or more performant than the old ways of accomplishing similar goals too (and that's an explicit design goal of new C++ features). I'm curious what features you're avoiding due to complexity or performance concerns?
