I am Catholic, I was raised Catholic, I am a practicing Catholic. But I say we need to agree to disagree. We have a shared mission around poverty, and I focus on that, because we do a lot with the Catholic Church around poverty alleviation. I'm always looking for: what is the common thread? What do we care about? What do we believe in? We believe in women around the world. We believe in all lives have equal value.

In the developing world, they don't have smartphones yet. They have the older plastic phones, but women are saving money on those, because they don't have access to banks. Having that access to digital money changes everything for her because she actually doesn't have to negotiate with her husband, which she will tell you is very hard in these circumstances, especially when the means are meager. She's expected to have money to pay for the kids' health or to help with the school fees.

I'm happy we have three healthy children and we'll stay with three healthy children.

As a woman finds economic opportunity, even if she's only earning a couple of dollars a day, if she can save it on her phone, she then makes different decisions for her household than her husband might.

Poverty disproportionately affects women around the world.

When I studied computer science at Duke University in the first half of the 1980s, I had professors who treated women differently than men. I kind of got used to it. At Microsoft, I had to use my elbows and make sure I spoke up at the table, but it was an incredibly meritocratic place. Outside, in the industry, I would feel the sexism. I'd walk into a room and until I proved my worth, everyone would assume that the guy presenting with me had credibility and I didn't.

The biggest pieces of work that we do are vaccines, because those save lives, and also family planning. Because if a woman can space the births of her children, it changes everything for her health and her child's health.
