Compartmentizing the code only matters if it works in the first place.

The main argument from senior folks is probably that vibe codes won't cut it for actual sizeable problem. There is complexity that can't be abstracted away just because we want to.

I think we're overestimating how much humans can keep in context. Throughout my career I've seen many instances that folks completely get it wrong and miss the context.

You're right, but it's also why vibe coding doesn't work IMHO.

We had the same situation with TDD: can we give out succinct specs and ignore what happens in the code if the specs are met ? For anything beside Hello world, the answer was no, absolutely not.

It still mattered that the logic was somewhat reasonable and you were not building a Rube Goldberg machine giving the right answers to the given tests 95% of the time. Especially as the tests didn't cover all the valid input/output nor all the possible error cases in the problem space.

It's because there's a lot happening that we need to have simple blocks that we can trust and not black boxes that were already beyond our understanding.
