Even if there are no first-time users anymore, I think computing in general can benefit from User Interfaces being developed as if they are developed for first-time users, and the advanced options layered underneath. This is where OS X gets things right. In addition, computers may be integrated into daily lives, but I think this definitely does not mean the opposite - that people have learned how to operate them properly, despite them being so integrated. If level of integration into society means that user interface does not need to cater to beginning users, there would be no designers left to make designs - only engineers (perish the thought :) But seriously -- and forgive me for using a car analogy -- but the basic operation of a car is actually simpler, rather than more complicated. To be fair, some OS X advanced options are in hair-pulling places, which I believe only underlines how hard it is to market computers to the masses with differing layers of knowledge
