Like it or not ETH is going to be around for a long while. It has the most support, the best leadership, and is furthest down the path of a viable network. Smart coins and smart contracts are simply a new tool in a programmers toolbox. That tool will continue to evolve and change until it has been specialized to individual needs, business uses cases and security. The future isn't set in stone, but tokens and coins are going to be a huge part of the world. We are just getting started, expect bumps and bruises, but don't be surprised when it doesn't go away.
