For me, I'd rather use my Pebble to do this.

> Initially, we experimented by building this as an app on Pebble, since it has a mic and I’m always wearing one. But, I realized quickly that this was suboptimal - it required me to use my other hand to press the button to start recording (lift-to-wake gestures and wake-words are too unreliable). This was tough to use while bicycling or carrying stuff.

I guess I don't bicycle or carry stuff enough for this to matter. And often when my hands are full, I have my AirPods in and can just ask Siri (and cross my fingers that she'll understand).

This seems neat, but I try to keep my life as simple as possible, which means not having a ring when I can use my watch/earbuds to do the same thing about 99% of the time.
