I think the Distributed Apps (dApps) are a good innovation and I can see where they would be useful beyond smart contracts. For example the Horse stud program someone came up with. Typically proprietary information sold at a high price, open sourced and distributed with the blockchain. It remains to be seen though if Bitcoin can implement distributed apps using a side chain or some tech.
Microsoft is behind Ethereum so, maybe it will actually take off and be the next big thing. First as I understand they implemented the blockchain in Azure cloud and now the language in Visual Studio.
I'm really curious if anyone has any real insight into whether Ethereum will take off or be pushed aside by Bitcoin. I personally have found it impossible to wade through the information out there to get a feeling one way or the other.
