Some thoughts on why I do not miss type systems as a #Clojure developer. 1/
Type systems give you more security, in exchange for making your code more rigid. You "lock the code down" with types, and in return you get some guarantees. This is in my experience not a good trade-off. 2/
In many ways it is parallell to gaining security by deploying less often. Maybe the added time spent indeed reduces errors, but the reduction in flexibility and speed is not worth it. 3/
The elobrate on that last point, the reduction in flexibility and speed also reduces your ability to fix errors. So you had better be sure it is worth it.
After almost 10 years as a full time Clojure developer, I still make lots of those silly type mistakes that a good type system would save me from. And then I fix them, usually within seconds or minutes. /5
Sometimes I even deploy those silly type mistakes to production, and they don't look so silly any more. However, frequent releases allow me to correct my mistake quickly. /6
These are trade-offs, but for me I prefer speed and flexibility over rigidity and safety both in my code and in my deployments. That might not be the right trade-off for you, but it's a part of why I still enjoy coding after all these years.
