The goal of ethereum is to replace the Internet (DNS, email, facebook, ...). It's not even remotely comparable to the goals of Bitcoin. I very much doubt that Bitcoin can move in this direction, for many reasons. I mean, for example the accounting system is a mess and is going to be removed. If not even something which is in the core can be fixed, how could one take one such large goals? The last 16 bips of 39 bips are in draft mode.
