It's apparent in other fields too. Reminds me of when Kanye wanted a song like "Sexy Back", so he made Stronger but it sounded "too muddy". He had a bunch of famous, great producers try to help but in the end caved and hired the producer of "Sexy Back". Kanye said it was fixed in five minutes.
Nobody wants to hear that one dev can be 50x better, but it's obvious that everyone has their own strengths and weaknesses and not every mind is replaceable.
