Think about it. What would you do if you were an Uber investor? Uber has a solid market, solid ecosystem, they just need to transition from humans to robots. If investors do nothing, they are guaranteed to lose on their already existing investment. By dumping more money into the org, they can either beat Waymo or follow Waymo, and in either case, the return on that investment is astronomical. The cost will drop so substantially that people will stop buying cars and throw money on ride sharing services. And its not like 1 will win the whole market right off the bat, its a huge world, with many markets, many price points, many potential sales strategies. It makes sense to try to make money on this, because the cost/benefit analysis says it's worth the gamble.
