DARPA figures out how to safely drive cars using LIDAR. Musk asked for a self driving car. Engineers come back the LIDAR solution. Musk fires them, says if humans can drive with two eyes, then so can computers. Cameras are cheaper than LIDAR. Second group tries it with cameras, can’t get it to work, asked why they can’t use LIDAR. Second group of engineers is fired. Third group comes up with something that ‘kind of works’. People die. Big companies avoid self driving altogether, even though we have a perfect solution with LIDAR, all because Musk wanted to save a buck and can’t get out of the way of his engineers.
