On the flip-side, if she takes the helm at Uber and brings it from the brink to a huge IPO, she'll achieve GOAT status.

She also has lots of experience dealing / managing a strong-willed founder with all the equity control.

I really don't know anything about her personality and style, but if she's the super ambitious Mayer-type, I think she'll go for it (assuming she sees a path forward when she gets to see the behind-the-scenes numbers).
