Exactly right. It just depends on where you stop in the hypothetical timeline of thought. If you stop in 2020, then yes, we have a ton of human engineers working on this problem. If you think out 2030, now more of it is handled by machines and testing routines/simple AIs. You think out to 2040 and now a good majority of it is automated. You think out to 2060 and you are begging for your life at the feet of a red-eyed monster or some variation of that future :)
