Another way new technology will impact ed tech in unexpected ways: "if there is a major blind spot in the AR space in 2019, it's the impact that blockchain technology will eventually have on the software distributed in AR clouds." Here's a good example: "In our current, web-based digital life, copying a photograph, for example, is trivial. And determining whether or not a digital photo is an original photo or just a copy of that digital photo can be difficult. Blockchain addresses this issue by allowing developers to create unique digital assets that users and other developers cannot copy." This has an impact for both commercial content (which cannot simply be copied) and also open content (which can restruct commercial uses). There's more, but this is the gist.
