The one thing I could never enjoy in C after getting used to languages like php and python is string handling. It isn't just dangerous but very tedious, complex and lacking elegance. Lack of a native string type and string operators really sucks.
I like being able to do "hello "+"world".
Another pro the author didn't mention is how my crapy code from 10yrs ago still works today. Can't say that about rust, go, python or most modern languages. It really sucks how "planned obsolecence" has crept it's way into programming languages.
