Yeah, it's also a pretty weird attitude. Certainly not one that scientifically or engineering-minded people should have. If someone alleges that your physics experiment has a problem, the proper answer isn't: "Oh yeah? Well I've got tenure and recently won a major award in my field. What kind of physics discoveries have you made lately?" Scientists actually lose a lot of reputation if they start getting that sort of attitude--- it's been the sad fate of some late-career scientists.
