As someone that has been using C++ extensively for the last 25 years, each release has felt as an incremental improvement. Yes, there are big chunks in each release that are harder to learn, but usually a team can introduce them at their own pace.

The fact that C++ is a very large and complex language and that makes it unapproachable is undeniable though, but I don't think the new releases make it significantly worse. If anything, I think that a some of the new stuff does ease the on-ramp a bit.
