There is a concept in post-modern philosophy called "hauntology". This theory posits that late-capitalist societies loose their ability to imagine different social orders; and cannot imagine the future except as high-tech versions of the current social order. To fill the void of novelty, the culture industry must constantly recycle and repackage old culture.
Anyway, this isn't a new phenomena, just a technology enabling us to resurrect live people instead of just fictional characters.
