With all due, respect... meh.
1) IMO, automatic assignment of copyright is a huge
boon for artists and writers. For example, a photographer might easily knock out 100 images in a single day. Should s/he fill out a form for each day's work? Or each image, perhaps? Or, a screenwriter can circulate a draft and numerous revisions, without needing to manage a ton of paperwork in order to protect that draft. Automatic assignment of copyright without the need to fill out paperwork is a tremendous benefit for individual artists.
2) While copyright may be too long, the idea that these terms are "destroying culture" is hyperbolic and absurd. E.g. hip-hop is a form of music that heavily relies upon sampling other recordings, and has obviously flourished despite the requirement both to get permission and pay royalties on those samples.
Obviously there are issues like the status of orphan works that require further refinement via legislation. But we are also living in an age where the average life span is far longer than it was in the 1700's and 1800's, where 28 years was a common copyright term; ergo, it makes sense to have terms that are, at a minimum, longer than that....
