No they are wrong saying it is ahead of it's time. Yeezus was a self serving exercise in how to overhype yourself and fail to deliver.
You can only say an album or an artist was "ahead of it's time" in retrospect after time has past (years not months). As example you could say Gary Numan was ahead of his time because the time has finally caught up to what he was doing on his albums in the 80's (even Reznor recognizes his influence on his career).

As for your comment about "hip hop in it's dying days" in the video, I think you are horribly wrong. What you should be saying instead is that, "the pop aspect of hip hop is killing itself". What we hear promoted to us on the radio/tv/advertising and whatnot is and always has been the lowest end of the spectrum with all forms of music. It is once you dig beneath the surface and get away from most the household names that you begin to see that hip hop is still very much alive, the powers that be have decided that positive, content filled, socially conscious or intelligent hip hop is not what they are going to promote and will not make them money even though it did quite well up to and during the "golden era".
