With Google I think the fear of moonshots is diminished because the ones they do take usually land on a nearby planet if they miss the moon. The projects that seem to die never really go away either, they live on in other forms as mentioned with Google Glass. Over the years I think we've all seen products that were way ahead of their time that seemed to flop but inspired another product years later. Glass is a good example of that given all of the AR and VR hype right now and I suspect that other projects will take the same path. I can say that I'd really like to see printed cars become a thing since the tooling to build panels for cars are incredibly expensive and they limit who can make and supply parts. Generally speaking printing body panels gives designers more flexibility, reduces the need to warehouse replacement parts and removes the expense of specific tooling to make replacement parts. If a project can lower the overall cost of one of the most expensive items we touch every day I see that as a big win.
