People often think about coding, but that's generally a small piece of it.

Typing is a form of structure, and especially a kind of documentation.

When encountering APIs of various kinds 'typing' is part of how they are expressed.

It's hard to build large monoliths without typing.

When working with 'wide scope' problems, when the typing is more oriented towards the data, that's another thing altogether, which is why I think for many systems untyped JS and Python works well enough there.

What most typed systems lack is a fluent way of mapping to 'data types' which are often external to the system, or at least externally defined.
