“Should this exist?” is not typically a question that technologists ask themselves, Caterina Fake says. The Flickr cofounder-turned-investor says that most entrepreneurs and engineers will ask themselves, “Can this exist, could this exist, how can we gain the funding to make this exist? Those are the conversations we’ve been having for the past 15 to 20 years about technology.”

But that narrative in tech is evolving, Fake tells WIRED on this week’s Gadget Lab podcast, from one of ideation, optimism, and changing the world, to a stark reality in which technology can do as much harm as good. The cracks are showing, and suddenly, Fake says, “People are asking, ‘Whoa, what have we done? Is this what we really wanted to build?’” That line of questioning was the genesis for her own podcast, “Should This Exist?”, a WaitWhat original series made in partnership with Quartz. 

Show notes: On this week’s show we also talked about the tragic Ethiopian Airlines crash, Elizabeth Warren’s call to break up Big Tech, and Apple’s upcoming media-related event. 

Additional note: WIRED’s Gadget Lab team taped this podcast before news broke about a mass shooting in Christchurch, New Zealand, that was live-streamed on the internet. At the time of publication, at least 49 people were reported to have been killed. WIRED will continue to follow this story.
