They are more likely to have one of those pesky families that get in the way of absolute, total devotion to the company.
They might even be so "uncommitted" to the work that they go home by 6pm.
Often older IT people will recognise a dead-end idea that they have tried before which failed and are hesitant for good reason.
When you are young you want to dazzle people with your own projects, when you get old you want to have money enough that you get time to dazzle people.
But in the end we never really dazzle people like we did when coding young, because we want to make younglings to feel encouragement, especially before college.
