if you've used cursor, you've probably felt how seamless fast apply can feel - fast apply is accurate and fast to the point where most don't even realize its a model
Absolutely, when stuff runs fast it's better UX compared to when the stuff runs slow.
I think what parent comments suggest is, the speed of applying a diff is not the major bottleneck in LLM-assisted coding, and improvements in other aspects are much more desirable (e.g. correctness, or even speed of thinking models themselves).
In a world where diff application is a real pain point, it's likely one of the last pain points in the field.
