Most definitely not. Ember (and its ecosystem) and Rust are the two open source projects that are currently consuming most of my time. I have easily spent as much time on the planning for Ember 2.0, HTMLBars, and Service Side Rendering as I have on Cargo and Rust over the past six months or so.

Also, both Ember and Rust are critical for my business (Skylight), and keeping them both strong and effective are key to my business interests ;)
