Came to make a similar point. There's lot of love for C and belief it's some superior language to modern ones. The reality is that C hasn't aged well as hardware has evolved. It's not that good as parallel programming, which is more prevalent considering most CPUs are multi-core. The ACM did a great write-up on this, https://queue.acm.org/detail.cfm?id=3212479

The bottom line is to echo your first statement, C is a tool, good for some tasks, not so good for others. Choose accordingly.
