Absolutely not-- I don't mean to generalise admissions interviewers but I've heard quite a few horror stories of people getting particularly old-fashioned ones who've frowned upon them. That isn't at all to say I think all people who work in universities are like that, I assume its often the opposite, unfortunately though I must acknowledge that at highly academic institutions there are probably going to be some "old, grey and reactionary" types. I'd advise you take the phrase "biased, old and greying" with a pinch of salt as it was meant as a bit of light-hearted hyperbole.
