I have met some of these people. Dynamic languages for them are a way to start doing stuff immediately. They view statically typed PLs as a hassle that’s always getting in the way. They want to get on with it.
I sympathize with that, a lot. But I feel that this mindset being brought to the work place is a very thin line to tread: one between “let’s deliver this in a reasonable timeframe” and a good old impatience. The former I respect. The latter: I don’t. Sprinting past proper tech due diligence is one of the best ways to accumulate tech debt.
Paying tech debt is not fun. It’s often extremely difficult, too, and I have witnessed it killing commercial projects.
All that being said, Elixir strikes a very good balance. But as your codebase and complexity grows, lack of static typing becomes more and more source of development slowdowns. Even that can be mitigated somewhat… but it does require paying the tech debt periodically. Which almost nobody wants to do.
