The ML world being nearly entirely in Python, much of it untyped (and that the Python type system is pretty weak) is really scary.

I think this has a ton to do with the mixed results from "vibe coding" we've seen as the codebase grows in scope and complexity. Agents seem to break down without a good type system. Same goes for JS.

I've just recently started on an Objective-C project using Cline, and it's like nirvana. I can code out an entire interface and have it implemented for me as I'm going. I see no reason it couldn't scale infinitely to massive LOC with good coding practices. The real killer feature is header files. Being able to have your entire projects headers in context at all time, along with a proper compiler for debugging, changes the game for how agents can reason on the whole codebase.
