501: Civilization 6 - Obsolescence
It's no secret our devices are designed to become useless, forcing us to upgrade whether we want to or not. But where did the idea of planned obsolescence come from, and does it have any benefits? This week, we examine obsolescence: its history, how it manifests today, and the ethics of creating disposable devices in a future of scarcity.

Repeat (updated): FLUX
(This episode first aired in September 2020, and has been updated to reflect that.) The human brain is always changing, and that constant state of flux helps us adapt to our ever-changing world. What would happen if we built our technologies and economic systems so that they function like our brains?

500: The Future of Distribution
The internet is a distributed system that's resilient and powerful because of that distributed nature, but much of our industrial era thinking is focused on centralization. We take a look at new opportunities for distribution from food to information.

How pandemic online shopping could be putting your data at risk
Throughout the pandemic much of our shopping has switched to online, which means retailers can gather a lot of data about us newly online shoppers. What are the ethics of getting — and using — that data? And if 'data is the new oil,' do retailers even want us to go back to the store?

495: Indigenous Futurisms
Stories about the future can offer insight into not only where we're going, but who we are. Thing is, traditionally, our most iconic images of the future are, for the most part, whitewashed and male-centric. Over time, the people in fictional future worlds have become more reflective of the world around us, but how do Indigenous Peoples fit into futuristic narratives? And not just in science fiction, but also in the tech world? + Grace Dillon, Ph.D., editor of Walking the Clouds: An anthology of Indigenous Science Fiction, professor of Anishinaabe and European descent in the Indigenous Nations Studies Program, in the School of Gender, Race, and Nations, at Portland State University + Dr. Lisa Richardson, strategic lead in Indigenous Health at the Women's College Hospital + Jason Edward Lewis, Professor of Design and Computation Arts. He is a digital media artist, poet and software designer. Founder of Obx Laboratory for Experimental Media. Director of the Initiative for Indigenous Futures.

A Spark Pandemic Retrospective - Where do we go from here?
2020 has been a long year, full of challenges, as well as opportunities to do things differently. We look back at the progress we've made in everything from transportation, to retail to working remotely. And we think about the steps we still need to take to stay safe, so we can ask: Where do we go from here?

494: The Spark Guide to Civilization, Part Four: Attention
We have been lamenting our loss of focus and blaming our short attention spans on technology for ages. But are our attention spans actually dwindling - or is it just that there are just so many things clamouring for our attention all the time? Thomas Hills, professor of psychology and director of the Behavioral and Data Science master's program at the University of Warwick in England, provides a historical overview of attention through the lens of tech and innovation. TikTok has been a key part of Toronto artist Hima Batavia's pandemic experience. It started with dance moves and moved towards engagement with social justice issues and into a variety of communities she never would have learned about if not for TikTok. Sarah Sharma, associate professor of media theory at ICCIT/Faculty of Information at the University of Toronto and the director of the McLuhan Centre for Culture and Technology, talks about the tech and media "solutions" to our current relationship with time, and what th…

493: Virtual Reality 22.214.171.124
Many activities have moved to our screens and online over the course of the pandemic, but we're still much more likely to invest in an ergonomic chair than a VR headset. So what still stands in the way of wider adoption of virtual reality? Bow Valley College has rolled out brand new virtual-reality training for their practical nursing program. Nora MacLachlan, Dean of Health and Community Studies, tells us how VR helps students develop empathy and practice more real-world disease processes for respiratory illnesses. Then, veteran airline pilot David Culos shares how he's using his unexpected sabbatical from flying planes during the pandemic to develop flight training that integrates elements of VR and AR. Finally, researcher Stephanie Llamas gives us a primer on VR, reviews the history of challenges in the industry, and discusses what the future may hold.

492: Social tech
As we interact more - and more often - with our digital technologies, those interactions tell us a lot about who we are. Can we analyze behaviour on social media for mental health insights? Researchers Munmun De Choudhury and Koustuv Saha discuss their latest study of the psychosocial effects of the COVID-19 pandemic, as gleaned from Twitter. Plus, robots already work on factory floors, in dangerous situations, and even cleaning our floors, but to truly interact with us humans, they're going to need to understand our world. Mark H. Lee, author of How to Grow a Robot, talks about building robots that "get" us, using... childhood development psychology! And: Better robots and AI require designing technology that doesn't actively harm humans. Can we get robots to learn things by letting them observe humans? Roboticist Odest Chadwicke Jenkins talks about training machines by (human) example, and how to avoid built-in racial bias in robotics and build more ethical AI.

491: The Spark Guide to Civilization, Part Three: Nostalgia
Throughout the pandemic we've seen a resurgence of retro hobbies like bread making, tie-dyeing clothes, and going to the drive-in. Why is nostalgia our natural response in times of crisis? And, fasten those jetpacks! A look at the surprising nostalgic pleasures of our past visions of the future.

Escape can offer a reprieve from daily COVID life. But if you can't physically go anywhere, immersing yourself in fictional worlds - like the ones of online games - can help with the social isolation of the pandemic. We talk to University of Saskatchewan professor Regan Mandryk about how videogames can help us relieve stress and connect with others during the pandemic and beyond. Plus, Spark producer Olsy Sorokina talks about the appeal of Animal Crossing. And, while fictional worlds can seem like escapism, fiction often offers us insight into truth that daily reality denies us. Stephanie Lepp uses deepfake video tech to create fictional epiphanies and moments of personal transformation by public figures like Mark Zuckerberg and Alex Jones. As use of the technology extends beyond political disinformation campaigns, what are the ethics of using deepfakes to enlighten rather than deceive?

Repeat: Truth decay
(This episode first aired in February 2020, and has been updated to reflect all that's happened in the world since.) How do we know what we know? In a digital landscape where social media dominates, and most people don't trust mainstream reporting, how can we be sure what we're seeing is actually real? It's a question technology journalist and Atlantic magazine staff writer Alexis Madrigal has contemplated a lot, and he's finding a lot of noise among the signals of truth. So what does this mean, more broadly? Social psychologist Arie Kruglanski says that humans need a shared concept of "truth" in order to have societal cohesion. And when that shared concept dissolves, bad things happen. Arie explains the collective risks of our unshared realities.

For all the good they give us, our personal tech has also become a major time suck. We lose hours of our waking lives to online experiences, especially in the past year, when our worlds became almost as tiny as the screens in our hands. Between work from home and doom-scrolling through social media, are we wasting time, or is this the "new normal" for spending it? And if we are going to be spending this much time online, can we improve online public spaces with better design? In her new book, Time Smart, behavioral scientist Ashley Whillans argues that if you improve your "time affluence," you'll lead a happier life. She offers some practical tips on how we can use the pandemic disruption to improve our relationship with time. Deb Roy, Executive Director of the MIT Media Lab and the MIT Laboratory for Social Machines, discusses how we can improve existing digital spaces. And Spark Senior Producer Michelle Parise shares her experience with what she calls "Nightly Doomscroll Avoidance."

488: The Spark Guide to Civilization, Part Two: Ventilation
Past pandemics have been a huge influence on the way we design our cities and our homes. So what can the history of this relationship between public health and public spaces teach us during the COVID-19 pandemic? Sara Jensen Carr explores these lessons in an upcoming book, The Topography of Wellness: Health and the American Urban Landscape. We also talk to architect Terrell Wong about how we can return some of the fresh air back into our homes and offices without decreasing energy efficiency or increasing hydro bills. And materials scientist Aaswath Raman explains how to use ancient natural cooling technology for more efficient thermal regulation.

487: We love robots
Humans have long been fascinated by the idea of automatons. But increasingly, robots are also just reality, as more work is automated - especially during the COVID-19 pandemic, to accommodate physical distancing. This week: a look at the new rules we need to prepare for a world of automation. During COVID-19, robots deliver groceries and medicine and disinfect public spaces. And sure, automation is great for routine, repetitive tasks - but what about things that require more nuance and social context, like caring for a sick patient? Roboticist Julie Carpenter discusses the social impact of rapid robot deployment during COVID-19 on humans. When it comes to robotics and AI, the dominant narrative is that automation will replace any jobs that can be made routine. Frank Pasquale, lawyer and author of New Laws of Robotics: Defending Human Expertise in the Age of AI, argues for a different future. He thinks the future of work involves collaboration between AI and human skill, in ways that ca…

Repeat: Post-truth expertise
This episode originally aired in June, 2020. Do you "trust the experts"? Or rather, in what circumstances do you trust the experts? In a complex world like ours, expertise is important, but specialization and hyper-focus can also get in the way of seeing the big picture. On the other hand, in rapidly evolving situations where the stakes are high and information is thin on the ground, measured expertise can easily be trumped by rumour and misinformation. + Among the challenges facing the world today is an "unprecedented crisis in public understanding," says sociologist Fuyuki Kurasawa. The Director of York University's Global Digital Citizenship Lab says there's an understandable delay between the public's need for knowledge and the response of experts, who are often cautious and concerned that they offer correct information. Into that gap slides social media, where rumors, innuendo, untruth and disinformation run rampant. So how do we address this? + We live in an era of extreme…

It used to be that efficiency meant getting something done in the fewest amount of steps. So how did we get to the world we live in now—where efficiency means whatever is cheapest and most convenient, regardless of how many steps it takes? The pursuit of efficiency at all costs has resulted in dramatic wealth concentration, as well as caused an alignment problem between human values and the design of machine learning algorithms. We feature more of Nora's conversations with Sidney Fussell, Rediet Abebe and Brian Christian, which began last week. + And efficiency has been a keyword in capitalism since the industrial revolution. But can efficiency go too far? Roger Martin, celebrated management thinker and former Dean of the University of Toronto's Rotman School of Business, says so, and that a fixation on efficiency has accelerated concentration of wealth and power in an unbalanced way. His new book, When More Is Not Better, offers some solutions.

485: Oh, Algorithms!
There's been a lot of discussion about algorithmic bias, but the focus has been on bias in historical data. However. it's a much bigger problem than that, so what about looking forward? That's what Spark is doing this week: A look at why it's so difficult to encode fairness, and why a rising computer science star still believes we can use machine learning for social good. + For the past several years, we've seen headlines about algorithms producing racist, nonsensical, and even dangerous results, alongside calls for greater transparency and oversight. But what's really at the heart of the problem? Sidney Fussell, a technology journalist at WIRED, looks at issues in machine learning, surveillance, and the abuse of data. + Machine learning and artificial intelligence research has shown time and again how difficult it can be to code AI that doesn’t produce unintentional bias. Companies like Google and Amazon have even come under fire for programming AI that’s been found to produce s…

484: The Spark Guide to Civilization, Part One: Movement
The first episode in our special Guide to Civilization series, will look at how tech from the wheel to just-in-time delivery architecture (and many things in between) have changed the way humans have been able to move, expand their horizons and shrink their world — along with the costs and benefits. We take a special look at the impact and role of the bicycle, which is consistently rated as the most significant invention in human history. And we end the episode with a peek into the future of movement, and what things may look like down the road, so to speak. + Technology has always abetted human movement; from the invention of wheels and aqueducts to drones and self-driving cars, the movement of people and goods has evolved in lockstep with the development of newer technologies. Transportation geographer Jean-Paul Rodrigue takes us through some of the most important inventions of transportation technology, and describes how they broadened human mobility. + The bicycle is one of th…

The human brain is always changing, and that constant state of flux helps us adapt to our ever-changing world. What would happen if we built our technologies and economic systems so that they function like our brains? + In his new book, Livewired, neuroscientist David Eagleman argues that far from being fixed, our brains constantly adapt to the changing external environment. There's a sort of 'survival of the fittest' battle going on inside our brains, as parts of the brain compete for space. That means the brain responds to new demands, whether that's living in a pandemic, or recovering from injury. + Beyond highlighting the myriad ways in which some social and political structures were ill-equipped to handle the constraints imposed by a global pandemic, COVID-19 has done an excellent job of demonstrating that the existing systems underpinning our world are in dire need of modernization and revitalization. Capitalism, whether applied to small business, large multinational conglomer…

482: The Politics of Technology
Technological development is politics by other means. From American companies moving to buy TikTok to governments advocating digital sovereignty and self-reliance, we seem to be entering a new era of techno-nationalism, where it's increasingly difficult to separate the politics, the economics, and the tech. And, extremist groups like the Boogaloo move from online forums to real world protests. Is the internet is fueling right wing extremism, and how do we de-escalate that extremism? + Throughout 2020, online extremist movements like QAnon and the Boogaloo Bois have gone from fringe internet groups and jokey memes to appearing at protests and crossing over into more traditional political groups. How has the internet fueled the growth of these movements? And can online tools also serve to de-escalate and de-radicalize? Vivek Venkatesh, UNESCO co-Chair in Prevention of Radicalisation and Violent Extremism, professor at Concordia University, explains. + The Trump administration has said…

Spark Summer Episode Ten: Concentration
In an age of digital devices and near constant distractions, many of us feel like our attention spans are shrinking. So this week on Spark, a handbook on how to concentrate in a distracting world. Stefan Van der Stigchel is a cognitive psychologist and author of Concentration: Staying Focused in Times of Distraction. He believes that concentration is like a muscle you have to work to maintain. As we age we find it more difficult to concentrate. Tarek Amer and fellow researchers found a possible upside: being scattered may help in creative thought. Tarek is also researching whether we can use older folks' distractibility as a way to deliver helpful reminders. Michael Shammas, a lawyer in New York who decided to unplug his headphones for a week. After spending years tethered to his phone while working at a corporate law firm, Michael decided he needed to shake things up. So he abandoned the comfort of his audio bubble, to see what he could learn by reconnecting with his inner monologu…
