C is outdated, even by systems programming language standards. Sorry, but it's true.

There's still room in the standard for one's complement, it denies all knowledge of multi-threaded programming, it has a bunch of impossible-to-use-safely functions in its standard library, etc. (This is just a tiny sample, there's so much else wrong that you could almost write an entire book about it.)

In my opinion, they should start by removing the substantial cruft. That would leave plenty of room for some sorely needed additions/modernizations.

In the name of backwards compatibility, they'll remove too little, they'll add too much unnecessarily stuff, and eventually, another systems programming language will catch on and start to slowly-but-surely replace C.
