Simple tasks like fiddling with an API json response with rust, haskell or ocaml are always going to take longer than with python. Now, doing it well will take as much time in any language. But a huge amount of time is spent not doing things well: - you try out ideas - you explore data shape, results and systems behavior - you demos things to get a sense of the solutions or sell something to management or clients Eventually, you will have a very well defined problem with an optimal solution. But this is the last mile, unless you work for nasa. E.G: currenly one of my client is a big financial structure, and they are creating a calculation engine. They have 3 experts on site, but they don't have the full understanding of the problem they want to solve, and disagree on the part they do understand. The result ? We have to rewrite a lot of code, and write even more code in an exploratory manner. This will likely go on for the next few years. You can wish for a better situations, or you can use a tool that make you productive in that situation.
