>It should come as even more of a surprise to find "Jeff Dean"
To find them, yes. To point out that they exist and the likely that you'll work with them is statistically insignificant? No.
The thing with intellectual labour is that some insights have immeasurable value. Some statistical outliers have such humongous intellectual capabilities that it's ridiculous how often they'll have great insights.
Of course, that won't stop people from trying to attach some numbers to it, even if their numbers are epistemologically shit.
