Another thought on "ld231782"'s idea about high-speed networks and copyrights:
But think about this: with the speed and ubiquity of networks, it now becomes possible for every author or creative artist to keep the only copies of his work. Then, he could post "links" to it anywhere in the world. When people pass around the work, they wouldn't pass around the work itself, they'd pass the "link". Whenever someone wants to view the work, the link points to the unchanging address for instantaneous downloading. A very small transaction charge is billed to the receiver by the sender.
With fast enough networks, we may see a big decline in sales of programs to end-users, as the software is made available as "on-line services." (Obviously this has always been going on, with service bureaus, circuit design services, etc.) To make this very concrete, I just installed a new release of the American Heritage Dictionary, a complete edition with definitions, thesaurus, anagrams, roots in Latin, Greek, German, Indo-European, etc. Look up a word and one gets an entire screenful of stuff, including detailed etymologies, usages, etc. Now what happens when a "dictionary server" offers to look up a word for, say, 10 cents? With fast enough networks, of the sort ld231782 proposes, this could replace the current system in which folks buy their own copies. (One would still need very high bandwidth programs like editors, word processors, drawing programs, etc., but some classes of software would be amenable to this kind of remote access use, especially with very fast networks.) There may be attempts to limit this, as with the laws which ban rental of CDs (but not videos, presumably because few people have two VCRS, while those renting CDs can presumably easily diub them onto cassettes). This could also reduce the costs of entry to the market, as new programs could be offered for sale or access in a low-cost way, such as through information markets like AMIX. I'm not taking a moral stand on either side, just noting one more consequence of extremely high-speed networks.
