I need to say, it's an interesting discussion.
I absolutely agree about IBM being a slow heavy bandwagon, but we are still talking about the first "baby" steps. Companies are still pivoting and trying to find a solid grip, because customers are ones who will pay after all. And yes, blockchain exists for years now, but the same goes with the story of the laser. It needs to become mature.
Mass adoption can appear in many ways but imho it is crucial that big players show their belief in the blockchain. And right now, it seems like they start to care about it.
