We do need new tools for multicore
I don't know if this new C++ is what we need, but there has been a need this past five years for a toolset that approaches the bare metal like C, but leverages the many core direction our processors are moving in.
Whatever the end product is, it should be able to handle heterogenous cores, because that's the direction platforms are moving in. Multiple different CPU cores, GPUs, hardware media decoders, varying forms of ALU, RNG's and PhysX units included in the silicon. The core system is getting revved these days far faster than before and with a lot of oddball things that didn't used to be considered part of the platform. The software tools are lagging these days, as dealing with this riotous mix always involves custom coding.
It's incredibly complex. I think we'll be groping about for an easy answer for a long time, and in the interim kernel coders are going to earn their money. More power to 'em. Whatever the answer is, it ain't Java, nor C#, nor COBOL.
