Given that apple has spent the last few years pushing the entire architectural glass industry forward by leaps and bounds (meaning, making the biggest glass panels ever created), this building in its construction alone is going to be a massive push forward for glass innovation.
Take a look at the renders, the entire face of the building is huge curved glass. So big that companies in China have been working with Apple just to figure out how these are going to be made. The thing about being the leader into a new field of manufacturing is that you pay alot up front, but market forces then quickly make prices drop and the entry barrier is lowered for everyone.
Think of this campus as Apple being to the glass industry what Germany was for the solar panel industry (an industry that finally broke loose after Germanies massive investment, thus allowing solar panel price to begin plunging around the world).
LOL !!
I love my hob with the Schott Ceran® German - oops, I mean Chinese - glass surface.
