It's maybe a bit of a startup-world, HN-blinkered assessment...but that's where we're talking, isn't it?

Even before JS became the language for everything, there was a good chunk of time - maybe between 2005 and 2015? - when Python and Ruby were dominant in this environment, and this dismissive attitude towards static typechecking was similarly dominant.

Of course in the enterprise space everyone was using Java, and in the systems space or game dev space everyone was using C++. But those worlds get a lot less airtime here.

Plus everyone on HN is a good little pg disciple, and Lisp is dynamically typed. If the One True Language doesn't need static typechecking (though SBCL offers some very helpful heuristics) surely it's not worth it. Right? Right?
