That video briefly mentions the CppCon 2014 talk by Mike Afton, "Data-oriented Design and C++". The talk was great, pretty much lined up with how I think of modern systems (treat RAM like disk: seeks take a long time, but streams will likely be able to maximize CPU usage)
But the questions at the end, and the resistance to these basic ideas, roughly "what about platform portability, programmer productivity, etc."; these questions were a bit shocking to me. Is this not a C++ conference? This was six years ago, so perhaps the machine constraints were not as well known back then, but it really shows how strongly the community culture will influence a language and its capabilities.
Basically right on point with what the GP is saying.
