The summary.
C IS WHAT OTHER LANGUAGES HIDE
Operating systems, runtimes and databases are built on it. Learning it explains how computers actually work.
It provides no memory safety, and the faults it permits — buffer overflows, use after freeing, undefined behaviour — are among the most exploited vulnerabilities in history.
Run sanitisers and static analysis during development, always. Code without warnings is not therefore correct.
MODERN C++ ADDRESSED ITS LARGEST WEAKNESS
Smart pointers and tying resource lifetime to object lifetime make leaks and missed cleanup far less likely.
Its remaining problem is size — agree which subset your team uses.
GO'S SMALL FEATURE SET IS THE POINT
Code looks the same regardless of who wrote it, builds are fast, and a static binary deploys by copying one file.
Its verbose error handling means every failure is visible and explicitly handled.
RUST TURNS DATA RACES INTO COMPILE-TIME ERRORS
Rather than intermittent runtime faults. The learning curve is real, and so is what it prevents.
DO NOT CHOOSE A SYSTEMS LANGUAGE FOR WORK THAT DOES NOT NEED ONE
Most applications are not performance-limited by their language.
