Chaps,
I don't think Bose was advocating not doing checks at all, merely that when you fly an aeroplane regularly your checks tend to speed up considerably, and you can dispense with the checklist (except for backing up emergency drills), doing them from memory instead. As you're no longer heads-in with a checklist, these checks can also now be done on the roll, much like a professional pilot does. A thorough after-flight walkround significantly reduces the time you have to spend on such the next time you fly.
But like I said before - I really don't think that people with pretty much zero knowledge of the guy in question, who only have only heard one person's testimony and viewpoint, should really be passing judgement!
