Jeff Dean is treated like God in these circles alongside the likes of Carmack. Despite that, I'd say he is appropriately rated.

There is not a single software team on planet earth that would not want Jeff as their technical leader.

It is like comparing a high school athlete to Usain Bolt.

I wouldn't necessarily put them on equal footing. One likely had the editorial review of many eyes, while the other was a more personal, empathetic message.
