Exposure notification apps were developed at the start of the pandemic, as technologists raced to help slow the spread of covid. The most common system was developed jointly by Google and Apple, and dozens of apps around the world were built using it—MIT Technology Review spent much of 2020 tracking them. The apps, which run on ordinary smartphones and rely on Bluetooth signals to operate, have weathered plenty of criticism over privacy worries and tech glitches. Many in the US have struggled with low numbers of downloads, while the UK recently had the opposite problem as people were deluged with alerts.
Now we’re looking back at how this technology rolled out, especially because it might offer lessons for the next phase of pandemic tech.
Susan Landau, a Tufts University professor in cybersecurity and computer science, is the author of People Count, a book on how and why contact tracing apps were built. She also published an essay in Science last week arguing that new technology to support public health should be thoroughly vetted for ways that it might add to unfairness and inequities already embedded in society.
“The pandemic will not be the last humans face,” Landau writes, calling for societies to “use and build tools and supporting health care policy” that will protect people’s rights, health, and safety and enable greater health-care equity.
This interview has been condensed and edited for clarity.
What have we learned since the rollout of covid apps, especially about how they could have worked differently or better?
The technologists who worked on the apps were really careful about making sure to talk to epidemiologists. What they probably didn’t think about enough was: These apps are going to change who gets notified about being potentially exposed to covid. They are going to change the delivery of [public health] services. That’s the conversation that didn’t happen.
For example, if I received an exposure notification last year, I would call my doctor, who’d say, “I want you to get tested for covid.” Maybe I would isolate myself in my bedroom, and my husband would bring me food. Maybe I wouldn’t go to the supermarket. But other than that, not much would change for me. I don’t drive a bus. I’m not a food service worker. For those people, getting an exposure notification is really different. You need to have social services to help support them, which is something public health knows about.

In Switzerland, if you get an exposure notification, and if the state says “Yeah, you need to quarantine,” they will ask, “What’s your job? Can you work from home?” And if you say no, the state will come in with some financial support to stay home. That’s putting in social infrastructure to support the exposure notification. Most places did not—the US, for example.
Epidemiologists study how disease spreads. Public health [experts] look at how we take care of people, and they have a different role.
re there other ways that the apps could have been designed differently? What would have made them more useful?
I think there’s certainly an argument for having 10% of the apps actually collect location, to be used only for medical purposes to understand the spread of the disease. When I talked to epidemiologists back in May and June 2020, they would say, “But if I can’t tell where it’s spreading, I’m losing what I need to know.” That’s a governance issue by Google and Apple.
There’s also the issue of how efficacious this is. That ties back in with the equity issue. I live in a somewhat rural area, and the closest house to me is several hundred feet away. I’m not going to get a Bluetooth signal from somebody else’s phone that results in an exposure notification. If my bedroom happens to be right against the bedroom of the apartment next door, I could get a whole bunch of exposure notifications if the person next door is ill—the signal can go through wood walls.
Why did privacy become so important to the designers of contact tracing apps?
Where you’ve been is really revelatory because it shows things like who you’ve been sleeping with, or whether you stop at the bar after work. It shows whether you go to the church on Thursdays at seven but you don’t ever go to the church any other time, and it turns out Alcoholics Anonymous meets at the church then. For human rights workers and journalists, it’s obvious that tracking who they’ve been

Stitching together the grid will save lives as extreme weather worsens
The blistering heat waves that set temperature records across much of the US in recent days have strained electricity systems, threatening to knock out power in vulnerable regions of the country.
The electricity has largely stayed online so far this summer, but there have been scattered problems and close calls already.
Heavy use of energy-sucking air-conditioners is the biggest problem. But intense heat can also reduce the output of power plants, blow transformers, and force power lines to sag. Severe droughts across large parts of the country have also significantly reduced the availability of hydroelectric power, according to the North American Electric Reliability Corporation (NERC).
It’s unlikely to get better soon. A number of grid operators may struggle to meet peak summer demand, creating the risk of rolling blackouts, the NERC report notes.
The nation’s isolated and antiquated grids are in desperate need of upgrades to keep the lights, heat, and air-conditioning on in the midst of extreme weather events that climate change is making more common, severe, and dangerous. One clear way to ease many of these issues is to more tightly integrate the country’s regional grids, stitching them together with more long-range transmission lines.
If electricity generated in one area can be more easily shared across much wider regions, power can simply flow to where it’s needed at those moments when customers crank up air-conditioners en masse, or when power plants or fuel supply lines fail amid soaring temperatures, wildfires, hurricanes, or other events, says Liza Reed, a research manager focused on transmission at the Niskanen Center, a Washington, DC, think tank.
The problem is it’s proved difficult to build more long-range transmission and grid interconnections for a variety of reasons, including the permitting challenges of erecting wires through private and public lands across cities, counties, and states and the reluctance of local authorities to forfeit control or submit to greater federal oversight.
The case of Texas
The unreliability of the US grid is not a new problem. Severe heat and winter storms have repeatedly exposed the frailty of electricity systems in recent years, leaving thousands to millions of people without power as temperatures spiked or plunged.
One of the fundamental challenges is that the grids today are highly fragmented. There are three main electricity networks within the US: the Eastern Grid, the Western Grid, and the Electric Reliability Council of Texas (ERCOT). But there are numerous regional transmission organizations within those first two systems, including the California Independent System Operator, Southwest Power Pool, PJM Interconnection, New York ISO, and more.
These grids form a complex web of networks operating under different regulators, rules and market structures, and often with limited connections between them.
A variety of regional transmission organizations oversee different parts of the nation’s aging and fragmented grids, which operate under different rules and with often limited connections between them.
ERCOT is especially isolated, in part because of the desire among local politicians, citizens, and power companies to avoid added competition, the hassle of following other states’ rules, and oversight from the Federal Energy Regulatory Commission (FERC). But the state offers a case study in why that can be a serious problem amid increasingly harsh climate conditions, Reed says.
The Texas grid operator pleaded with customers several times earlier this month to cut electricity use as blistering summer temperatures created demand surges that threatened to outstrip supply and require rolling blackouts. Low wind conditions, cloud cover, and outages at fossil-fuel power plants added to the strains.
