The technical side of Ethereum's efficacy is 100% an engineering exercise.

Although the Ethereum blockchain is a public blockchain, it is great to see private and consortium blockchains using the Ethereum code base actively under development.

The Ethereum client is literally a fork of Chromium's webkit backend. The idea is that users can build their own interfaces with HTML/JavaScript just like websites, and they will be viewable with the browser much like websites are viewable with the web browser.

Initially, I thought that Ethereum was a thing that would be used for people to write simple financial scripts. As it turns out, people are writing stuff like Augur on top of it.

I generally support just about every secession attempt that comes along. If, in the future, there is that kind of a dispute in Ethereum, I'd definitely be quite happy to see Ethereum A go in one direction and Ethereum B go the other.

When I came up with Ethereum, my first first thought was, 'Okay, this thing is too good to be true.' As it turned out, the core Ethereum idea was good - fundamentally, completely sound.
