We’re back with part two of Hard Fork Live (see last week’s episode for part one). This week, Patrick Collison, Stripe’s chief executive, joins us onstage for a wide-ranging conversation about how Silicon Valley could unleash greater progress, from building new housing to curing diseases, and why he believes prestige television is a waste of time. Then, after a quick costume change, Kathryn Zealand, the chief executive of Skip, joins us to talk about her company’s robot pants. We test them out live on a StairMaster. Finally, we end the show by taking questions from audience members.Guests:Patrick Collison, Co-founder and C.E.O. of StripeKathryn Zealand, Founder and C.E.O. of Skip We want to hear from you.
