Machines Like Us

Many unlocked mysteries remain about the workings of the human brain. Neuroscientists are making discoveries that are helping us to better understand the brain and correct preconceived notions about how it works. With the dawn of the information age, the brain’s processing was often compared to that of a computer. But the problem with this analogy is that it suggested the human brain was hard-wired, able to work in one particular way only, much as if it were a computer chip, and which, if damaged, could not reroute itself or restore function to a damaged pathway.

Taylor Owen’s guest this week on the Big Tech podcast is a leading scholar of neuroplasticity, which is the ability of the brain to change its neural networks through growth and reorganization. Dr. Norman Doidge is a psychiatrist and author of The Brain That Changes Itself and The Brain’s Way of Healing. His work points to just how malleable the brain can be.

Dr. Doidge talks about the brain’s potential to heal but also warns of the darker side of neuroplasticity, which is that our brains adapt to negative influences just as they do to positive ones. Today, our time spent in front of a screen and how we interact with technology are having significant impacts on our brains, and those of our children, affecting attention span, memory and recall, and behaviour. And all of these changes have societal implications.

What Does Real Democracy Look Like?

Democracy is in decline globally. It’s one year since the Capitol Hill insurrection, and many worry that the United States’ democratic system is continuing to crumble. Freedom House, an America think tank, says that nearly three-quarters of the world’s population lives in a country that experienced democratic deterioration last year. The rise of illiberalism is one reason for this, but another may be that democratic governments simply haven’t been performing all that well in recent years.

In this episode of Big Tech, host Taylor Owen speaks with Hélène Landemore, author of Open Democracy and Debating Democracy and professor of political science at Yale University. Landemore’s work explores the limitations of casting a vote every few years for a candidate or political party and how in practice that isn’t a very democratic process. “Electoral democracy is a closed democracy where power is restricted to people who can win elections,” she says. Positions on issues become entrenched within party lines; powerful lobbyists exert influence; and representatives, looking ahead to the next election, lack political will to lead in the here and now.

In an open democracy, citizens would be called on to debate issues and create policy solutions for problems. “If you include more people in the conversation, in the deliberation, you get the benefits of cognitive diversity, the difficulties of looking at problems and coming up with solutions, which benefits the group ultimately,” Landemore explains. In response to the yellow jacket movement in France, the government asked 150 citizens to come up with climate policies. Over seven weekend meetings, that group came up with 149 proposals on how to reduce France’s greenhouse gas emissions. In Ireland, a group of citizens was tasked with deliberating the abortion topic, a sensitive issue that was deadlocked in the political arena. The group included pro-life and pro-choice individuals and, rather than descending into partisan mud-slinging, was able to come to the recommendation, after much civil deliberation, that abortion be decriminalized.

Landemore sees the French and Irish examples as precedents for further exploration and experimentation and that “it means potentially going through constitutional reforms to create a fourth or so chamber called the House of the People or something else, where it would be like a parliament but just made up of randomly selected citizens.”

How Europe Is Trying to Rein in Big Tech

Governments around the world are looking at their legal frameworks and how they apply to the digital technologies and platforms that have brought widespread disruptive change to their economies, societies and politics. Most governments are aware that their regulations are inadequate to address the challenges of an industry that crosses borders and pervades all aspects of daily life. Three regulatory approaches are emerging: the restrictive regime of the Chinese state; the lax, free-market approach of the United States; and the regulatory frameworks of the European Union, which are miles ahead of those of any other Western democratic country.

In this episode of Big Tech, host Taylor Owen speaks with Mark Scott, the chief technology correspondent at Politico, about the state of digital technology and platform regulations in Europe.

Following the success of implementing the General Data Protection Regulation, which went into effect in 2018, the European Parliament currently has three big policy proposals in the works: the Digital Services Act, the Digital Markets Act and the Artificial Intelligence Act. Taylor and Mark discuss how each of these proposals will impact the tech sector and discuss their potential for adoption across Europe — and how many other nations, including Canada, are modelling similar regulations within their own countries.
