Is there an actual problem here that airships solve? Is getting cargo across the Pacific one or two days faster (and that's presumably a best case, since airships are heavily weather and wind dependent) actually that valuable? I would have though the scale of international shipping would anyway mean its pretty cheap to set up a continuous stream of cargo, which airships would struggle to replicate in any efficient way.
Honestly, it sounds like a cool thing to work on, but this article is not convincing about the potential market. I can easily imagine former SpaceX and Hyperloop engineers thinking a cool technology will simply find a market, but that's not really what Elon Musk did with SpaceX.
