Agreed. The "even a mom can do it" is broken on so many levels. There's a documentary about the developers of Mozilla, and one of them makes a comment while golfing (I think) in response to this cliche. He says, "My mother writes optimizing compilers." Can't remember the film or the person, but they were wearing launch t-shirts that read "zaro boogs" (zero bugs) still sticks in my head.
EDIT: Pretty sure it was "Code Rush", 2000. https://en.wikipedia.org/wiki/Code_Rush
