Uber teams up with Google's Waymo on self-driving cars

The two companies were previously fierce rivals, with financial analysts predicting that Uber would eventually have to get rid of human drivers in order to be highly profitable and justify its massive valuation. The company began investing heavily in artificial intelligence, and then it even hired away a top Google self-driving engineer, Anthony Levandowski. Google later sued Uber in 2017, accusing Levandowski of stealing trade secrets, and the two companies eventually settled.
