Correct me if I'm wrong, but it seems to me that you're talking about something very close to the ethereum project.
Doesn't the Ethereum project plan to eliminate all other coins? I've heard that and heard it called "one blockchain to rule them all."
I don't like the idea of a central authority for blockchain-based systems. I think the distributed networks should themselves be distributed.
Correct me if I'm wrong, but all the videos on Ethereum seem to be so far reaching it's kind of hard to understand if it can/will be done. Whereas Bitcoin and Namecoin are very easy to understand, for me, at least on a surface level. I've also met people who are absolutely evangelical about Ethereum who cannot for the life of them explain it. I'm not saying anything against it, at all, but I've yet to have someone explain it cogently. Also, where is it at in development? I know there's some code, but last I checked (about a month ago) it looked like another coin with a few lines added. I'm not saying "it's not there"....there are too many projects to vet line by line, especially working on my own full-time project (which is very easy to define, and is out now).
But I sure hear a lot about the healing magical powers of Ethereum to revolutionize the world, without a lot of people really knowing what it is or where it's at in existing as a product/project, or when it will be ready for full testing. Kind of reminds me of the "Gabo" phenomena on the Simpsons maybe.
When a friend I know calls me and said "I've installed Ethereum, it kicks ass, let me help you get it running", I'll be excited and drop whatever I'm doing. Like three years ago when someone did that for me with Bitcoin.
I'd love Ethereum to do everything everyone says it will do.
I'm not criticizing it for not being fully formed. I'm suggesting things that are far less fully formed in this thread. But people talk about Ethereum in hushed, excited tones, and talk like it's already running everywhere. Is it? And is it "one blockchain to rule them all"?
I think the real answer is more coins, not less coins. Not just for security, not just for new uses, but even just on a user level / value for marketing the idea of coins. For instance, I think Dogecoin is silly and have even turned down offers of people donating some to me because I can't be bothered to run yet another wallet. But it's important because it's "friendly" and it will be many non-technically minded peoples' first coin.
