Interesting to read! HTML5 developers call it a future proof technology. It is because every new device that has sprung up in last few years is designed in a way to support HTML5 in one way or the other. To elaborate we can say that being futuristic means it can be poured in any container to deliver best results. The favorable containers can be iOS or Android, a web app, ePUB. So, undoubtedly HTML5 is in-thing in the future but its usage will depend on the type of content or audience you cater.
