Are you familiar with the adage that the longer something has been around, the longer it will likely continue to be around? Also known as the Lindy effect.

Anyway my point is that C++ has been around for 40 years (and a dominant language for 30 of those), so it will likely be around longer than anything that surfaced in the last 6 years. Plus, mode new things are just refinements or variations on a theme, so you hardly need to learn them, just keep abreast of what's interesting about them.
