Jack keeps proving that new riffs are endless. Many years ago, people were saying that classic hard rock is gone. Jack White shows up and proves everyone wrong and keeps doing it, IMO. Lazaretto is a good example, and it is heavily influenced by the 1980s.
At a certain point some guitarist who acquire a lot of skill start thinking about music like it's figure skating and difficulty becomes the only standard they care about. Guitarists love Joe Satriani and Steve Vai and no one else does. White is the opposite side of that spectrum.
I used to play guitar like Satriani. Used to do about 5 hours practice a day, had real dedication to it (obviously family, work etc gets in the way after a while do I tailed off). Everyone said "dont learn all the theory, it ruins music" and tbh, it didnt. I think the people who hate White and co tend to have an inflated sense of ego or something. The two I remember that did hate him were into that prog and shred style. Cant really say its all.
