Or, you know. You could actually learn how to write good code at the most powerful level. That's a radical thought.
I did, and that's why I'm using Python. I'm capable of writing web services in C, but who the hell's got time for that craziness? Also consider Amdahl's Law: in most of stuff I write, the "running code to process data" bit is a teensy portion of wall clock time. Much more is spent in socket handshaking or waiting for database queries to finish. Out of a 50ms request lifecycle, perhaps 1ms is spent inside a box that I have complete control of. Even if I rewrote it in assembler (C is for high-level pansies) to be 1000x faster, the request would still take 49.001ms. An assload of work porting security-sensitive code into an untyped languages so that the end result can be 2% faster? Yeah, no. My boss would fire me with a quickness if I proposed that.
I'd be much more likely to rewrite performance-critical code in Go or Rust. They're as fast as C but without the death of a thousand cuts like gotofail waiting to ruin your careful planning. Life's too short to waste it hacking in languages that hate you and make you want to look incompetent.
