You'd kind-of be dogging your kids if they didn't get at least a little dose of the messes we have to deal with as developers.
It's like if you got them all excited about writing slick screensavers, and they have a ball, then when it's time to get a job they realize it's all about grinding out the same boring shit everyone else is doing, and having a million little bullshit-meeting-micro-dominance struggles over everything from FP-vs-OOP down to tabs-vs-spaces.
At least they'll have been warned.
