Travis Kalanick changed the world. Who can follow that?
Kalanick could one day make a bid to return if Uber falters again, just as Steve Jobs took back control of Apple Inc. after being ousted.

Travis Kalanick made Uber Inc. a global force by breaking all the rules. The next chief executive will have to be a diplomat, power-sharer and defender of the internal controls long neglected at the world's most valuable startup. It's a tall order.
Kalanick's paper net worth $6.7 billion
While Kalanick's surprise resignation clears the way for a new leader, finding someone of the right caliber who's willing to take on such a difficult job won't be easy. Uber was already struggling in its hunt for a number two to fill a chief operating officer role. That was cast as adult supervision for Kalanick as the company tried to end a crisis over sexual harassment allegations and other wrongdoings.
A new CEO will have more clout to make real changes than a second-in-command ever would have. That said, Kalanick, who's said to control a majority of the votings rights at Uber, will keep his board seat. So the incoming boss will still have a powerful founder breathing down their neck.
The guessing game about replacements, some surely fanciful, has started already. Names like Facebook Inc. number two Sheryl Sandberg and Hewlett Packard boss Meg Whitman are circulating in the media. It might be easier for a star from another industry to play the outsider. The New York Times recently reported that David Cush, former CEO of Virgin America, was being considered as chief operating officer.
Indeed, convincing genuine Silicon Valley royalty to join may be difficult given the scale of the challenge at Uber. The company, whose last private valuation was $69 billion, is increasing revenue quickly: it was $6.5 billion last year. But losses are still heavy even after it withdrew from China where it capitulated to a tough local rival.
The idea that ride-hailing would be a winner-takes-all market, where the best technology prevails, has turned out to be wrong. In the U.S., Lyft has been rejuvenated. Meanwhile, Uber clones are securing big funding rounds in places from India to Latin America and the Middle East.
It's a lot to take on, even for a seasoned executive. I wonder if the newcomer won't end up being somewhat of a placeholder while Kalanick works on some serious self-improvement. He has been through a personal tragedy recently after his mother died in an accident and his father remains ill. Kalanick could one day make a bid to return if Uber falters again, just as Steve Jobs took back control of Apple Inc. after being ousted.
