Seconded. I find it's the power-hungry managers in the industry who push this idea that unless a software engineer knows "literally everything about everything" they'll always be inferior, especially as compared to some abstract "Perfect Google Engineer" which I've never actually met in real life and seems a lot like Bigfoot.
