3. If it becomes truly production ready within the next 10 years or so. By "truly production ready" I mean a Uber/taxi competitor in at least 20 alpha global cities outside of the US. Otherwise yeah, it's going to be a great tech but with a 30+ years ROI.
But waymo created the category by showing it is possible.
