We would be living in an interestingly different world were digital media not to be protected by copyright, instead where there were some open standard of crypto encapsulating each work and locking it to devices. This standard crypto would be strong (with increasing keylengths as more CPU horsepower becomes available), taking concerted effort of many computers working a long time to bruteforce.
- We wouldn't see perpetual copyright
- Works of high interest to society would presumably be effectively public domain more quickly
- Authors might be more inclined to offer reverse-bounties for their works
