That's a good joke, cynicism aside. What I think is significant here is that a massive industry has a clear use case for it, and it's an industry that is fighting for its life with respect to SSDs. A 10x capacity jump might justify an initial investment as well, especially if the durability is a huge improvement. Economics of cloud datacenters may bridge the divide. Also, I'd posit that that graphene doesn't need to be a perfect uniform surface for the HDD platter. If they can just get usable sections (ahem, sectors?) then it becomes workable and usable.
