Great article. Modern C++ has come a really long way. I think lots of people have no idea about the newer features of the standard library and how much they minimize footguns.
Lambdas, a modern C++ feature, can borrow from the stack and escape the stack. (This led to one of the more memorable bugs I've been part of debugging.) It's hard to take any claims about modern C++ seriously when the WG thought this was an acceptable feature to ship.
Yeah, it's great that the C++ community starts to take safety in consideration, but one has to admit that safety always comes as the last priority, behind compatibility, convenience, performance and expressiveness.
