I'd agree with the "Gen X & Gen Y/millennials not being as car-centric and not caring about the hobby" statement as being false. Being born in the same year as my newly purchased DeLorean is pretty awesome! And by the number of people my age I see pulling out their cell phones to take a picture of my car while I'm out driving would also prove that some of us still care!
Of course, I will say that I was just at the San Diego International Auto Show yesterday and was pretty unimpressed. I think just the sheer number of new car models being produced every year makes it hard these days to really be "car-centric".
Regardless, hopefully the magazine is wrong though since I just bought mine two months ago!
