I said serious in the sense of something they seriously believe they can deliver. Those wild predictions on unrealistic timeframes are for the stock market. For an example: Sergei Brin, Sebastian Thrun, and Elon Musk were all interested in self-driving cars. Musk has been making materially misleading statements promising to deliver L5 in the next year or so many times since 2013, and still doesn’t have more than L2. Waymo did not promise things they couldn’t deliver, treated safety as a top priority, and is expanding L4 taxi services around the country. They’re all interested, Waymo is serious, but Musk’s strategy has made him enormously rich and I think that’s always been his top priority.
