What is this “sacred knowledge?”

Is it knowing how to write a regex without a reference, or maybe implementing a distributed ec postgres cluster using bash, ooh how about writing a minimum cnn in C for edge classification ooohhh wooowee…

Ever worked construction? There’s hammer swingers that need one swing per nail and never miss. Or plasterers that make chalk look like marble. How about a high voltage lineman that can switch a 20kv oil-cooled transformer in less than 15 minutes to get the power to the school back on

No different from any tradesman - we’re not special
