Sorry, I didn't mean it to be trolling, I just meant it more or less literally. If Rust (for example) gets used for things like Mercurial and Mozilla, is that bad? I'm not saying Python shouldn't care, if it could improve the startup time without sacrificing other things. But presumably the transition from py2 to py3 was not intending to make things slower, it was intending to solve other problems. There are almost always tradeoffs. Even the mercurial folks quoted in the article said that the things py3 solved were not what they needed. That's a good indicator that Python is not the right language (anymore) for what they're doing.

I am primarily a Python programmer, but if Rust, Go, etc. take over as the language of choice in certain cases, I don't think that's a bad thing. Which doesn't mean one shouldn't write an article to highlight this cost of not having short startup time, just in case this cost wasn't understood by Guido, et al. But my guess (and it's only a guess), is that it was.
