you dont get the devs who spend their day on twitter instead of writing code to read your thread if it doesnt mention "modern" at least once. /s

Its quite obvious that the author "dumbs down" all the information for a very non-developer audience, so I assume that gives some leniency. If you tell people that we have had things like mmap() for decades, they may start asking too many questions about why every piece of software underperforms so horribly below what was possible decades ago.

Bit of a rant, but I feel that we lose a little bit of potential every time a developer calls operator<< on a std::istream in a loop.
