Still doesn't solve the bigger problem - that neither designers nor publishers actually embraced the digital medium. They've been treating the web as if it was a poster - something for the designers to show off on. The only thing the current "responsive design" fad brought up is that the poster now changes its layout with size in a somewhat intelligent manner. But they're still drawing posters. We're still getting only text + pictures + occasional video. What about interactive descriptions? Embedded simulations? Models that we can explore, or play with? Nowhere to be found, except in occasional essay by Bret Victor.

That's because up until recently, the only tools users have to interact have been 2D. If 3D becomes a thing, more designers will embrace it and think of new ways to communicate ideas in that space.

Also, in a discussion about communicating efficiently over limited bandwidth, and the possibility removing web fonts, 3D spaces is in a completely opposite direction. We'd have to load vector files and texture maps so that the 3D space doesn't look like crap.

Also, there's a limit to how much input a human can process. There's a reason why certain sites have gotten more simple to restrict distractions.
