No need to! ObjC developers have soldiered on for years and years without such fanciness.

I think the difference is that Objective-C is dynamically typed from the start, while Go tries to be statically typed first, with the added ability to work with those types dynamically. The latter leads to a lot of additional and arguably ugly code that I expect scares a lot of people off.

This. ObjC devs have always been self-selected to not care about static typing, especially in collections.
