Why would you?

Large parts of the industry does really work with low(er) level languages.

Even people who went through C/C++ in their formal education/start of their career may have not used it for a long time.

Learning C is a time honored tradition. I’m surprised that I’ve to defend C language on a forum like HN.

Treating everything a popularity contest is definitely not the best way, right?

Everyone who knows pointers had to learn them at some point.

Are you honestly surprised?
