Look, we need more than just promises. C++ is charting a future to the past in the most torturously slow process possible, primarily because of absolutely intrasigent performance obsession that won't even admit the possibility of a 1% performance overhead for bounds checks. The C++ steering committee are the real extremists that are holding back the entire software industry because of a sacred cow and a free pass to externalize that cost onto the rest of us in terms of significantly less secure software.
