SL's problem is it is a game-like product written by people who have no idea how to make games.
Bitcoin solves the double spend problem, and you could think of your presence at a particular point in a virtual world as "spending" your time. You could use Bitcoin to ensure no user is in two places at once.
As for 3D interfaces, what do you call a RL coffee mug, door handle, gear shift, or paper book? We use 3D interfaces so much in everyday life that they dissolve into the background.
Coffees cups, yes currently they'll be around for a while longer. To much culture attached ATM.
As for the "death of paper books," guess what? Ebook market share has stopped growing. It will never get anywhere near 100%. Paper books have many advantages over ebooks. Just try flipping quickly through an ebook, or passing it on to your children as an heirloom.
What replaces cups, pray tell?
We use 3d interfaces in the real world. They do not translate to the 2d world.
real 3D widgets are there to save time, or provide a service that isn't possible without them. In the computer world, they just get in the way. When starting from scratch, why hobble your self with something designed for a world we don't control?
They are similar to animated transitions, sure they look good, but they eat time. (apple spaces really Pisses me off, why the fuck do you want to slow me down? you can tell the designer never uses them.)
I am a bit worried about the efficiency of using "internet 2.0" instead of today's internet.
Imagine controlling your character to find that video, you cannot recall the name of on some video server. In 3D.
Although it sounds like a very tasty project to work on.
No, the problem is text (amongst many other media) has only disadvantage in 3D. Second life has many more problems than centralization... Most people don't care about such matters and notice SL has basically zero impact on the world right now.
