Villasenor on ‘Deepfakes’ and the Uncertainty of Truth

Public Policy Professor John Villasenor wrote a piece for the Brookings Institution on “deepfakes” and the uncertainty of truth as a result. Villasenor defined deepfakes as intentionally manipulated videos that make a person appear to say or do something they, in fact, did not. He suggested three strategies to address this issue: deepfake detection technology, legal and legislative remedies, and an increase in public awareness. Artificial intelligence would detect image inconsistencies due to video manipulation, he said, adding that legal and legislative actions must strike a balance to protect people from deepfakes without overstepping. He said viewers can combat deepfakes by refusing to believe questionable videos are real. “That knowledge won’t stop deepfakes, but it can certainly help blunt their impact,” he said. Villasenor is currently a nonresident senior fellow in Governance Studies and the Center for Technology Innovation at the Brookings Institution.


 

Getting a Handle on the Future Transportation experts join with policymakers and entrepreneurs to tackle the impact of disruptive technology on urban mobility

By Will Livesley-O’Neill

Getting around Southern California has never been easy. But the infamously congested region has grown even more complicated with the arrival of new private services — including ridehail companies such as Lyft and Uber and electric scooter operators such as Bird and Lime — looking to disrupt how people travel.

Motorized scooters are often seen at UCLA.

As in any field impacted by technology-fueled disruption, transportation policymakers want to find ways to adapt. And that requires taking stock of what the transportation system is meant to do and, more importantly, whom it is meant to serve.

This was the focus of the 28th annual UCLA Lake Arrowhead Symposium, hosted by the Institute of Transportation Studies (UCLA ITS) and Lewis Center for Regional Policy Studies, in October. At the university’s retreat center in the San Bernardino Mountains, dozens of the nation’s leading experts on transportation and land use policy pondered the symposium’s theme, “From Public Transit to Public Mobility.”

The changing nature of travel means different things for elected officials, planners, academics, advocates and tech leaders. But everyone fundamentally agrees that, as LA Metro chief planning officer and symposium panelist Therese McMillan put it, “there’s a public interest in how private activity happens in a public space.” The modes may change, but the mission of a safe, effective, accessible transportation system remains the same.

John Zimmer, co-founder and president of Lyft, set the tone for a discussion of balance between tradition and innovation. Lyft has been actively expanding beyond ridehailing into other forms of mobility, including e-scooters and automated vehicles. The company’s stated goal of providing more options for consumers and reducing the number of people driving

alone benefits the environment — as well as those profiting from the service.

But the way that some tech companies roll out new products — a “move fast and break things” model — often leads to public backlash.

Southern California has been ground zero for arguments about the traffic tie-ups and sidewalk clutter allegedly caused by ridehailing and scooters. Public officials are being forced to make policy on the fly — although some such as Francie Stefan, chief mobility officer in Santa Monica, describe that as an opportunity. Santa Monica recently partnered with Lyft, Uber, Bird and Lime to introduce new regulations on the number of e-vehicles in the city while funding infrastructure improvements.

“[We] made a conscious choice to embrace new technology and work through some of the kinks that are inherent in change,” Stefan says.

Technology also gives cities the chance to innovate and to fulfill some hard-to-implement planning goals. Willa Ng, an associate director at Google’s Sidewalk Labs, presented an example at her panel on “coding  the curb.”

“If we need to do more stuff at the curb, and we need to have those spaces constantly turning over, we can’t have it managed by a static aluminum sign,” Ng explains, outlining how creating a flexible digital management system could allow the same section of curb to be used for parking, ridehail drop-offs, delivery unloading, or as a bike and scooter lane depending on the time of day. New transportation technology can crowd and complicate the use of public space, but it can also help make sure the space is better used to benefit the most people.

For example, Anastasia Loukaitou-Sideris, a professor of urban planning at UCLA Luskin, recently spoke to the University of California for a story and accompanying video about e-scooters titled, “What the battle over scooters gets wrong.”

Urban planners recently adopted a model known as “complete streets” that involves rethinking how shared space is divided between a street and a sidewalk, Loukaitou-Sideris says. This model abandons the assumption that streets are for cars and sidewalks are for pedestrians.

“The complete street perceives the street as a space where different transportation modes can coexist: not only cars, but also buses, and lanes for trams, bicycles and scooters,” according to Loukaitou-Sideris. “Nobody wants to compromise the safety of anyone by mixing these modes. So that’s where planning and design needs to come in.”

People-centered design — of services, systems and infrastructure — is at center stage in these policy discussions. Technology needs to be a tool to help improve transportation for people, not an end goal in itself.

“A lot of people are really annoyed with private capital coming into the mobility space without understanding people’s travel needs,” says Clarrissa Cabansagan of the Bay Area climate change nonprofit TransForm. But tech disruption will be worthwhile if it provides people with more options to get around besides driving their own car, she says.

Professor Brian Taylor of UCLA Luskin Urban Planning

Urban Planning Professor Brian D. Taylor, director of UCLA ITS, co-authored a groundbreaking 2018 study that found that Southern Californians are buying more cars than ever and turning away from public transit. That’s the exact opposite outcome of what policymakers had sought and shows the need to set new priorities for shared public spaces.

“We have to manage the automobile more intelligently. We can’t just allow people to drive anywhere they want, anytime they want,” Taylor says. “We need to create environments that are more conducive to travel by foot, by bike, by scooter or by public transit.”

New and old mobility services could work hand-in-hand to reduce private car travel. Ideally, technology should improve, not replace or eliminate, traditional transit, according to transportation experts.

“We should really focus on making the core strength of transit something we do incredibly well,” says Houston-based planner and author Christof Spieler, who spoke at the conference. With transit ridership falling across most of the country, new policies need to make riding the bus as easy as hailing a Lyft, he says, noting that public transit can move many more people much more effectively than any ridehail vehicle or scooter.

Bay Area transportation advocate Ratna Amin argues that focusing on riders as people, not cogs in a machine, is key.

“When we think about public transit as a utility, we focus on the bare minimum: We got the service out, it’s clean enough, the doors opened, the bus stop is there and it’s labeled,” Amin says. “We need to actually talk to people and find out what their experience is, and try different possibilities out to see if they improve the experience.”

Seattle is one of just a few American cities to see an increase in transit ridership in recent years. Terry White, the deputy general manager of Seattle’s transit operator, believes one factor has been key to success: an emphasis on making sure service is equitable.

“Transportation is a human right for everyone,” White says. “We’re trying to make sure everyone gets an opportunity to

be mobile.”

That’s ultimately what a better transportation system will mean — mobility for all, regardless of whether they take a bus or ride a scooter. Efficient use of public space lessens the need for gridlocked, polluting private vehicles.

The disruption of old transit methods is still in its early stages, with plenty of blind spots to be navigated. But as Juan Matute, deputy director of UCLA ITS, recently told LA Weekly, it’s important to remember that the disruption from new technology is likely to lessen over time.

“The safety hazards are comparable to those for automobile use,” Matute said of the new innovations, particularly e-scooters. “We’ve had over 100 years to figure out a lot of things.”

Transportation and Isolation: Serious Challenges for Diverse, Older Angelenos Research conducted by UCLA Luskin and USC Leonard Davis — and supported by AARP — examines travel, technology and mobility issues

In an effort to identify solutions to improve the lives of older adults and people of all ages and abilities, the UCLA Luskin School of Public Affairs and USC Leonard Davis School of Gerontology, with the support of AARP, recently conducted surveys of diverse, older Angelenos, exploring their travel patterns, use of technology, and the mobility problems they face.

“We united on one common goal, the importance for understanding community needs, opportunities, and barriers that can support, create and sustain livable and age-friendly communities in Los Angeles,” said Nancy McPherson, State Director of AARP. “We know that the more connected and engaged people are with their community, the more likely they are to age successfully and remain living in their homes for as long as possible, as the vast majority wish to do.”

The UCLA research team focused on identifying mobility and travel patterns by conducting focus groups and interviews with 81 older adults in the neighborhoods of Koreatown, Westlake and East Hollywood, including adults visiting St. Barnabas Senior Services (SBSS), a local organization that provides health and social services. The UCLA report, “Bolstering Mobility and Transportation Options for Low-Income Older Adults,” found that:

  • Participants expressed difficulty in getting around, often endure long transit trips and uncomfortable or scary walking environments and social hazards that could cause them to trip and fall, significantly reducing their independence and quality of life.
  • For many, walking around their neighborhoods is the primary mode of transportation; however, there are significant physical and social impediments that constrain mobility.
  • A small number own cars and many rely on family and friends to drive them. Use of point-to-point travel services (e.g., taxis, ride-hailing services) is rare and constrained by finances.
  • Many lack competency with technology to order ride-hailing services.
  • Mobility constraints affect the number and frequency of trips.
  • Differences exist among study participants in regard to the numbers of social and recreational trips. Older adults visiting SBSS take a larger number of daily trips and have a higher likelihood of making social and recreational trips than those who are not visiting SBSS.

“Mobility affects the quality of life. Decreased mobility means also decreased access to city amenities or jobs, and socialization opportunities, as well as a higher risk for social isolation. Our findings suggest that certain improvements both in the physical environment and in the transit and paratransit services can help increase the mobility of low-income, older adults, and we articulate these improvements in our report,” said Anastasia Loukaitou-Sideris, Associate Dean of the UCLA Luskin School of Public Affairs. “We are welcoming the opportunity to join forces with the AARP and our USC colleagues and advocate for more age-friendly California cities.”

In recent years, there has been a growing focus on the consequences of loneliness and isolation, especially among older adults. While adoption of technology and social media has the potential to reduce isolation, issues such as cost, disinterest and lack of the skills needed to use various devices may hinder older adults’ adoption. Los Angeles’ ethnically, linguistically and geographically diverse population of older adults made it an ideal location for the USC Leonard School of Gerontology to explore how this population uses technology and the extent to which they believe it can improve connectivity and reduce isolation.

The USC research team conducted six focus groups in English, Spanish and Korean at SBSS with 48 older adults living in a low-income area of Los Angeles, home to a diverse, largely immigrant population. Key findings from this report, “Aging in Place in Los Angeles: Recognizing Challenges to Social Connectedness,” include:

  • A relatively high use of some technology among this engaged group, as well as a wide range in social connectivity with family, friends, and members of the community;
  • Although some older adults did not have the resources or the desire to use technology, others used mobile phones, smart phones, tablets, and computers – either in combination or alone – for purposes of contacting their family and friends, accessing health care information, getting the news, shopping, and watching television;
  • Cost, disinterest, and lack of the skills needed to use various devices hindered older adults’ adoption of technology and social media;
  • Many older adults indicated a reluctance to adopt newer technology because they preferred to communicate in-person and they expressed concerns that technology is too complicated or too expensive; others used it for entertainment, to plan local and long-distance travels, and to communicate with their loved ones.

“Our findings suggest that although technology isn’t a cure all for loneliness, it can be a tool in the tool box for addressing social isolation. Policy makers and tech developers need to consider how older adults currently use technology, how it can better suit their needs, and barriers that prevent them from using it effectively,” said Kate Wilber, USC Leonard Davis School of Gerontology professor. “We are thankful that AARP and our UCLA collaborators recognize the importance of addressing social isolation and look forward to working toward solutions that benefit older adults in Los Angeles and beyond.”

Tilly on Economic Imbalance Exacerbated by Amazon’s Search for HQ2

Urban Planning Professor Chris Tilly discussed Amazon’s failure to reverse the concentration of wealth and power in the United States in a Ringer article explaining disappointment in the company’s choice for a second headquarters. Amazon garnered national attention when it announced the search for a home for “HQ2,” inviting cities with at least 1 million residents, an established mass transit system and proximity to an international airport to apply. Many saw this as an opportunity to spur economic growth in cities beyond established hubs. However, Amazon ultimately chose two smaller sites in New York and Virginia — both close to CEO Jeff Bezos’ personal homes in Washington, D.C., and New York City. Many cities vying to lure HQ2 were never realistic options for Amazon, Tilly said. He added, “The whole thing was a show with the ultimate purpose of getting the best possible benefits from one or more cities on the short list they already had in mind. I don’t think there was a genuine process of scoring the map of the United States.” 



Villasenor on the Growing Promise of Artificial Intelligence

In a recent article for research think-tank Brookings, UCLA Luskin Public Policy Professor John Villasenor commented on the increasing presence of artificial intelligence in diverse fields such as geopolitics, manufacturing, trade, agriculture and transportation. As research and funding increase at a dramatic rate, innovation in AI is becoming ever more synonymous with technological progress and economic growth. Villasenor enumerates the many advantages of working with artificial intelligence, claiming that “AI will make it easier to predict violent storms. It can help with drug development to help reduce the impact of disease. It can improve agricultural yields, and help manage the complexities of the supply chain for food [and] medicine.” However, AI is more than a marker of technological progress: Villasenor ends his piece with the overarching conclusion that “as we move towards the middle of the 21st century, a nation’s geopolitical standing and its strength in AI will be increasingly intertwined.”


 

Storper Weighs In on the Battle for the Bay Area’s Soul

Professor Michael Storper of UCLA Luskin Urban Planning speaks about the “contest for the heart and soul of the Bay Area” in a wide-ranging interview with Public Knowledge. Storper says the region’s rich history of social connectivity has underpinned its economic success. Now, in the face of rising inequality, “Silicon Valley capitalism must be more than about disrupting markets and daily life.” The Bay Area must draw on its “deep intellectual and humanistic traditions,” he said, “and let’s hope that it is the beginning of a new wave of balancing the advantages of the Information Age with a new public space.”

 


 

Carnesale Joins Board of California Council on Science and Technology

The California Council on Science and Technology (CCST) has added Albert Carnesale, UCLA chancellor emeritus and professor emeritus of public policy and mechanical and aerospace engineering to its Board of Directors. Also joining the board, which provides strategic vision and direction for CCST, is Alexandra Navrotsky of UC Davis. “Dr. Navrotsky and Dr. Carnesale have made exceptional contributions to their respective scientific fields and applications on the global stage,” said CCST Board Chair Charles F. Kennel in a news release. “Their deep insights and experiences into the societal importance of science and technology will greatly inform CCST’s mission and service to state leaders in California.” Carnesale joined UCLA in 1997 and was chancellor through 2006. He is the author or co-author of six books and more than 100 articles on a wide range of subjects, including national security strategy, arms control and nuclear proliferation. CCST is a nonpartisan, nonprofit organization that engages experts in science and technology to advise state policymakers.

Villasenor Is Among 70+ Internet Luminaries Ringing the Alarm on EU Copyright Filtering Proposal 

John Villasenor, UCLA Luskin professor of public policy, joined more than 70 influential tech leaders to warn the European Parliament that a copyright bill it is considering poses “an imminent threat to the future” of the Internet. At issue is Article 13, which would require Internet platforms to automatically filter uploaded content. “Article 13 takes an unprecedented step towards the transformation of the Internet, from an open platform for sharing and innovation into a tool for the automated surveillance and control of its users,” said the letter co-signed by Villasenor, who is also a professor of electrical engineering and management. Three weeks after the letter was published, the European Parliament voted to send the bill back to the drawing board. A revised copyright bill will be debated in September.

Big Data and the Commuter

UCLA Institute of Transportation Studies and Global Public Affairs at UCLA Luskin co-hosted a lecture on April 18, 2018, by Antoine Cormount, Cities and Digital Technology chair at the Sciences Po university in Paris. Courmont’s discussion, “Big Data and Re-composition of Urban Governance in the Digital Era: The Case of the Waze App,” focused primarily on the potential for conflict between public and private goals when firms and governments use different data sets. The popular driving app Waze, Courmont explained, relies heavily on real-time crowdsourced data that is applied to help its users shorten commute times. Conversely, government-backed infrastructure like traffic cameras and roadway sensors are often employed to help reduce congestion — rather than short-term drive times. Because Waze will often route drivers through residential streets — clogging roads not designed for commuter traffic, the spillover effect from Waze’s data gathering causes regional traffic problems, governments say. Waze contends that poor urban planning has led to a need for its commute-shortening algorithms. Governments can implement a number of policies that could reduce Waze’ effectiveness, Courmont said. He also noted that Waze and governments have the potential to collaborate, share data and disseminate information on road closures and traffic hazards. — Zev Hurwitz
