critical idk. But i can answer your points against. What if you did not have to choose ? It gives you all of that. There is no "steep learning curve". I had a sysadmin that never did anything functional pushing code to prod in less than a week. This is not a single case. This is the widely reported result across companies switching to elixir. Regarding rigidity: quite the contrary. In my experience elixir and its take on FP are faaaaar less rigid than an oop one. I am not going to bad talk any of the languages you offered. I will simply say that i disagree with basically every single one of the characteristics you offer for them. Regarding how much productive... Well the most extreme example is whatsapp doing it all with 8 backend engineers. All of whatsapp. Recently RocketMortgage had equivalent results. In the case of rocketmortgage, it was wihtout any prior experience in the ecosystem. This was for Erlang, but all the companies using elixir report equivalent results. PagerDuty and Bleacher Report are probably the most visible one. So in the end... do what work for you ? I do think you are missing the point a bit with your argument, which is what i will fight. But if other languages work for you, great for you :)
