I would disagree. Bitcoin was revolutionary even if it didn't "invent anything new".
I remember about this web services called Webvan, or Fridge van. It was launched a couple of years before the dot com bubble. Those times were way before what we now call "Internet of things". But basically it was internet of things: you would put a sensor in your fridge, which would "read" what's in it, and then order autonomously what you consumed, without any input from you, automating your grocery shopping. It didn't take out. As a matter of fact, it crashed pretty bad during the dot com bubble and, even if other players tried to revive it under different names, it never really took off.
In a way, Webvan and Bitcoin are similar, because they both just combined already existing technologies. None of them invented something completely new, like, for instance, quantum computing. But, for some reason, Bitcoin took off, while automated grocery shopping didn't.
At least that's my point of view, and, as always, we can safely agree to disagree on this topic.
