Very true, but this is more like Coca-Cola going bankrupt.... You know it's a possibility and in the case of humans we all are going to die at some point (and his surgery can't hide he's human too :p ), so this was rather inevitable. But for such an iconic person to pass, is just extremely sad.

It's by the way not true that Michael only influenced music in the 80s and 90s, he did so till this very day and beyond. When it comes to music videos, dance moves, music style, live performances. He singlehandedly ignited the music industry.

I doubt anyone will ever become as famous as he was / is.
