      Turns out performance is not a property of the language, but of the implementation and the performance of the implementation is a product of (some inherent properties of the language) and (how much resources you're willing to spend on making it fast)https://twitter.com/cemerick/status/1088887866908950533 …

      even this is probably not qualified enough. it's more like a product of - the alignment between the language design and the underlying target system (VM, hardware) - how much you're willing to spend - the characteristics of all the software already written in the language

      Omar Rizwan Retweeted Omar Rizwan

      underlying point here is like another argument I've made, that lots of things in technology come down to capital as much as clever engineering (hardware support is a form of capital!)https://twitter.com/rsnous/status/1084635004544651264 …

      Omar Rizwan added,

      Omar Rizwan @rsnous
      a lot of these reasons boil down to something like "path dependence" i.e. there is a pile of capital already invested in language X, so even if language Y has better inherent properties, language X is the better overall proposition

      Replying to @rsnous

      (You probably already know this, but) the capital invested isn't exogenous w.r.t. language properties. I think two or three companies (Google, Dropbox, ???) have tried to make a fast Python JIT and they've all given up and concluded that it's harder to do for Python than for js.
