You could also have guessed it when you noticed it was a kid student showing up (and off) with a lengthy critic on the historical evolution of UNIX tools and others OSes and tools that he discovered a couple of years ago, while you possibly were using them and watching them evolve while he was still in his father's bollocks (and some of us (not me) were working on UNIXes while his father was a kid). You know what to expect in this case, especially if you remember having produced the same kind of over-confident and yet uninformed rant in your days :-) (I do :-D )
