Plenty of people use C++ for web apps. It doesn't take a good coder a lot of time to use them. Those apps also run crazy fast compared to Python apps, even on embedded boards. Plus they support every security, speed, or reliability-enhancing tech ever developed for native code.

So, I'd rather use a higher-level language (and do) for most web-application development. I also love Python for its tradeoffs, esp productivity & readability. Yet, there are valid use-cases for native web apps esp where performance or memory-usage matters.
