A "transformative visual experience" isn't a product, or a vision. It's a technology in search of a problem. They needed to demonstrate a clear use case, and determine if that was achievable with what they had. If it wasn't, they could always be an R&D lab instead. I don't know what you actually do with a $10k light field thing even if it is cool. If you want to make a category-defining product (which $2.6b in funding strongly suggests), you have to define the category, not just ship a thing.
