Ethereum reminds me of what happened to the web: the desire to add code. The blockchain by itself wasn't good enough so Ethereum added code to it, just like HTML wasn't good enough so people added applets, Flash, and JavaScript.

I understand why they would want to do this but I think it gets the priorities wrong. It prioritizes features and functionality over security and reliability. Given how hostile the Internet has become I think this is a mistake.

My guess is that Ethereum is only a couple of scandals away from being perceived as a fundamentally insecure platform. Bitcoin has its own problems and it may not survive either. Perhaps another cryoto currency can learn from the mistakes of both and deliver something better?
