I don’t know about other senior developers, but I can tell you about me. I have decades of experience and an amount of wisdom. I’ve written some bad, some good, and a couple great apps over the years.
But I’m no Jedi.
Despite my long history of writing (and debugging) pretty “hardcore” software for Mac and iOS, I still managed to miss a (now-)obvious red flag in my configuration.
We’re all just a bunch of dummies flailing about wildly out here!
Years ago a similarly “hardcore” developer told me that if he gets to lunchtime without realizing he made a colossally simple mistake, the day is a win. Count me in with him, Brent, and Chris: nobody knows it all, and sometimes we even miss things that we do know.
There’s a lot of peace to be found accepting that this happens to everybody.
