Uber's dysfunctional and toxic work culture is the headline reason for its current chaos. It threatened Uber's reputation and ability to attract and keep top talent.
But, as CEO Travis Kalanick goes on leave and loses some of his power when he comes back, a risk remains to Uber's out-of-this-world, $68 billion valuation. Dogged by a lawsuit that it stole its self-driving technology from Waymo, Uber has lost the undisputed perception of a company as likely as any to be central to the future of transportation. The Waymo case threatens to leave Uber armed with one of the world's best-known brand names, but still a taxi service, and less prepared than competitors for the widely forecast shift to self-driving cars, a transformation that Kalanick himself has called "basically existential" for Uber.
