I think you're arguing from a position of willful ignorance. The article is clear on how it lauds C++'s std::printnl, not printf.

http://en.cppreference.com/w/cpp/io/println.html

Here's what the article argues:

> With std::format, C++ has gained a modern, powerful, and safe formatting system that ends the classic, error‑prone printf mechanisms. std::format is not merely convenient but fully type‑safe: the compiler checks that placeholders and data types match.

Solid remark, and the consensus on how std::printnl and std::format are an important improvement over std::cout or C's printf.
