The biggest problem is deterioration of the media. The storage life of CD media isn't even close to 50,000 years. Normal aluminum film CDs are only good for about 100 years and recordable CD media is around 20 (although it varies widely depending on the type). The longest lasting ones, gold film CD masters, will last less than 1,000 years.
Oh well. I guess they'll find out the hard way 50,000 years from now.
