Here is an interesting podcast with Austin Russell, who is CEO of Luminar Technologies. Luminar specializes in LIDAR vision systems for autonomous vehicles and has already cut deals with carmakers such as a Volvo. Starting as early as next year, Volvo hopes to start rolling out "fully autonomous highway driving" using LIDAR. And, supposedly, Luminar makes the best kind of LIDAR with ranges of up to 250m. But not everyone believes that LIDAR will be a necessary component of autonomy going forward. Tesla instead relies on vision (lots of cameras and fancy AI software), and Elon Musk has famously said that anyone relying on LIDAR will ultimately be doomed. Time will tell, though I am in the LIDAR camp because of the recency bias that this podcast has created. And in the interim, Luminar going public at the end of last year has made Austin Russell the youngest self-made billionaire in America.
