Saying that you disagree and saying at the same time that you rewrote it in Elixir makes me think that wasn't a good use of the money. They will have problems hiring for it and it isn't even performant compared to other languages you could have written into if you really wanted to save money (i.e: golang). Of course I don't have all the context, but, I cannot imagine any circumstance when rewriting some server side logic in elixir would be useful from a PoV of cost savings..

How do you know it wasn't a good use of the money? The client's site has been up for a year since then without any issues for 1/4th of the cost. Their investment in this stack wasn't much. Hiring wasn't a BIG problem, but it did take time. We used that savings to find a dev to maintain the site. By RAW numbers, GoLang or something else maybe faster, for sure, but it will definitely extend the time to develop something like Wordpress because its frameworks I've tried (Eg. Gorilla) need more effort compared to using something like Phoenix that I use. Plus, a lot of devs were already onto Ruby, it's easier to onboard them into Elixir than GoLang. > Of course I don't have all the context, but, I cannot imagine any circumstance when rewriting some server side logic in elixir would be useful from a PoV of cost savings.. I think you may not have worked with a high traffic site, just by swapping languages alone you get insane cost savings for that scale because it quickly adds up. Even if your new language is just 0.1 second faster per user, for a million users, it adds up really fast. As I mentioned, just by this switch alone we brought down the cost to 1/4th. I believe GoLang or something else may have drastically reduced further, but it has the same downsides of Elixir (Harder to find talent for, learning curve). I'm a pure Elixir consultant, so I chose it. My client is more than happy with this outcome.

  Yes, I kind of agree with everything you said actually! Apart from Elixir from a cost savings on infrastructure PoV, if that's how you wanted to frame it (since the context of the HN submission is about changing languages for better performance or not, and Elixir not being particularly fast).
