Design, writing specs: Same amount of time.

Finding the holes in your specs under automation: time spent is returned 10x

Writing code: Human 15 lines per minute. LLM: 600+ lines per minute

Functional Validation: same time per iteration. Fewer bugs with LLM when properly specified => fewer iterations. Increased awareness of LLM escaping specification boundaries feeds back into increasing quality of spec writing => fewer bugs.
