Re: What would make you switch to Bluray?
Well, not just capacity-- also ease of use and transport (compare an LP to a CD, or even VHS to DVD. Stone tablets to ebooks, especially), production (if books were printed on metal plates, their prices would be incredibly high), and ease of creation (compare how difficult and time consuming it would be for you to personally carve something into rock, and compare that to a brush and scroll, and then compare that to a word processor and a keyboard)
For archival purposes, I've heard some ideas about using holographic media which would be able to be read without computers (using, for example, a magnifying glass, or just a sharp eye), as well as being processed by computers, but I'm not sure how much of that is theory and how much of that has been archived. Also not sure about how well they would hold up, but they seemed pretty sturdy.
Anyway, it's not like BR is going to have a significantly shorter lifespan than DVD; and even if it did, it's not like many of us are going to notice it before the disks get scratched beyond repair or tossed in a microwave for fun. And Archival is maintaining the knowledge you do have, not just tossing your media into a cool dry cave and hoping for the best. We're always going to need people copying media from one place to another to preserve it; even stone tablets will break, erode, or simply become untranslatable, eventually. This is one reason why the internet (and torrenting) will be great once copyright is overturned (or through things like Creative Commons, it's 'kill the pirates' form falls into disuse); it creates multiple copies of a file all over the place, and encourages people to share it, especially if it's something people are looking for (read: leaching).
