The funny thing about big innovations like GaN is that they become mundane and invisible after the hype, but end up in a lot of places without most people realising it (like for Apple users, it's not GaN chargers, it's just the MacBook charger).

Even graphene has a lot of real-world applications that are far removed from the sci-fi marketing of speculators, but offer a great advance over past technology.
