I found the slides of his talk there: https://meetingcpp.com/tl_files/2014/talks/executors-meetingcpp.pdf
In one of the last pages, he is talking about the "async desaster" (which I, as a non-native speaker, read as "async disaster"). What disaster was he referring to exactly?
async
is written in the code font. He's referring specifically to theasync
function, which was a hastily added high-level threading facility added to C++11, basically just so there would be one, which has poorly specified semantics and thus isn't that useful for real-world programs in my experience. He's probably referring to that.
