I remember in 2017 being pretty convinced that we'd have something commercially operating within 5 years and my wife being skeptical. As recently as a few months ago, I still felt pretty good about that prediction. WayMo's non-launch launch has made me a lot less bullish, since I really had assumed they were almost there, at least in terms of Phoenix. And 2022 is looking a whole lot closer these days.
