It's 43 years old (times have changed), and while I'm sure C still has its places, I think it's time to come to terms with the fact that people suck at handling memory manually and making sure type conversions are safe & a host of other security risks.
Other, safer languages can accomplish many of the same things C does these days.
Again, I'm not calling for the end of C, but in a lot of situations, it's just asking for it now.
