Yeah, here is some additional info:<p>This is the typical C fanboism that sells C as the AD of systems programming.<p>Here are some other languages, for those that don&#x27;t want to go through the article, about well known systems programming languages before C had any relevance outside AT&amp;T.<p>- Algol on B5000 (1961)<p>- PL&#x2F;I on System 360 (1964)<p>- PL&#x2F;M on CP&#x2F;M and AS&#x2F;400 firmware (1972)<p>- Mesa on Xerox PARC Alto (1970)<p>- XPL on Sytem&#x2F;360 (1971)<p>- HAL&#x2F;S on AP-101 (1970)<p>- JOVIAL on 465L (1970)<p>- CPL on Titan and Atlas (1963)<p>- BCPL on IBM 7094 (1970)<p>But lets pretend C (1972) was the first one.<p>Interesting enough, just like they did with Go, C dropped most of the features used by the other systems programming languages of the day.
