In all seriousness, I think that should be something that ought to be changed as a compromise of sorts. Otherwise, works by dead 4x great-grandfathers still being part of copyright and possibly estate lawsuits (which are more frequent than some realize) would be the case. Not quite what the original copyright laws of the 19th century had in mind when they aimed to protect the living authors and not those who would be born after his grandchildren had died off. I think 70 years after author death is a good range, but I will also admit that corporations should have different protections since that is the heart and soul of their existence.
