Tech industry leaders have been spending a lot less time lately talking about their plans to change the world — and a lot more time promising to change their work culture. It seems like every day, another tech leader resigns or gets fired as more women come forward with stories of harassment and discrimination.

The New York Times profiled more than two-dozen women last week, who detailed countless examples of systemic sexism in tech start-ups.

Last month - Uber founder Travis Kalanick resigned under pressure as CEO - following an internal review of the company's handling of harassment claims and other questionable practices.

But not everyone thinks sexism is such a pervasive problem. Speaking at an event in San Francisco, Marissa Mayer, the former head of Yahoo, blamed Kalanick's failure on Uber's meteoric rise to success. "I just don't think he knew," she said. "When your company scales that quickly, it's hard."

So is  there a problem? Or isn't there? And, if there is, will it get fixed? Shirley Leung, business columnist for The Boston Globe and a WGBH contributor; Michael Greeley, a cofounder and partner at Flare Capital Partners; and C.A. Webb, founder of the 50-50 project and cofounder and former partner at Underscore VC, joined Jim Braude on “Greater Boston” to discuss.
