While gesturing at religion and saying he's a fundamentalist is an easy rhetorical technique, it doesn't add much. Yes good resources do exist, but they are few and far between. The number of new undergraduates from cs or software engineering who learned to think in the ways needed to make low latency applications are a rounding error based on my experience with them. Most forgot it, weren't taught it well, or never saw it at all. They are more worried about learning the syntax of the current hot framework rather than on anything even resembling "Avoid copies, never allocate, keep the hot path local".
The religious comparison is also a telling one given the state of the industry; for we aren't the theologian, we're the common folk looking for someone or something to follow in order to write better code.
Who are Casey's alternatives? Gesturing the cppcon as a learning resource has "read research papers to learn about a field" vibes. They can be highly informative and worth the effort, but not for beginners.
Who are Casey's contemporaries? If he's a fundamentalist then the atheists are nowhere to be seen by the beginners. Instead we have agile ceremony shamans, clean code bible missionaries, tdd doomsday cults, oop/rust/haskell/etc. zealots, a thriving megachurch industry of Lambda schools, and the mother of all cargo cults masquerading as web dev.
