The gang dives back into the world of sensors this week, with a conversation about lidar, autonomous vehicles and surviving the "trough of disappointment" with Angus Pacala of Ouster Lidar. Unlike some other lidar companies, which are a bet on the market for autonomous vehicles, Ouster has taken a diversified approach to the business and now has hundreds of customers in a wide variety of fields. We discuss why that strategy has paid off, how Ouster is validating its sensors, why autonomous vehicles will likely always have lidar, and where the sensor business is headed.
