On this show we explore three different AI and machine-generated music technologies; vocal emulators that allow you to deep fake a singer or rapper’s voice, AI-generated compositions and text-to-music generators like Google Music LM and Open AI’s Jukebox, and musical improvisation technologies. We listen to the variety of music these technologies generate, and two guitarists face off against an AI in improvised guitar solos.  Along the way, we talk to philosophers of music Robin James and...

Curtis is setting aside a large chunk of money to donate to charity, and it is up to us to persuade him where he should donate it. Luckily, philosophers, economists, and the nonprofit world have been thinking a lot about this issue in recent years. On this episode, effective altruism’s defenders and critics try to persuade Curtis of where he should donate. Who is the most effective in persuading an ordinary person as to the right way to donate to charity? And do the recent scandals involving...

Willy and Heidi were both gig workers for Shipt, the fast-delivery app for groceries or same-day shopping. In 2020, they both realised: the pay algorithm had changed. Now, they couldn’t tell what a job would pay, or whether it would earn or lose them money. Instead of just taking it, they decided to fight back. In the gig economy, companies like Shipt, Instacart, and UberEats all use black box pay algorithms to try and get workers to accept gigs but hide information from them to do so. Early...

We explore the lives of people who are in love with their AI chatbots. Replika is a chatbot designed to adapt to the emotional needs of its users. It is a good enough surrogate for human interaction that many people have decided that it can fulfill their romantic needs. The question is whether these kinds of romantic attachments are real, illusory, or good for the people involved. Apps like Replika represent the future of love and sex for a subpopulation of people, so we discuss the ethics of...

A zoopolis is a future society that philosophers envision where wild, domesticated, and denizen animals have full political and legal rights. What would that look like? In this episode, we look at how animals were put on trial in medieval European courts, and how animal rights advocates are bringing animals back into the courtrooms to sue people and the US government. We then look at what the science of animal minds tells us about how much agency animals have, and envision what political and...

When Justin’s mom was diagnosed with cancer, he knew he wanted to keep talking to her after she died. So together they made an AI version of her, training it on her speech patterns and memories. Now he is scaling his findings so that anyone can continue their relationships with loved ones after their deaths. Justin even believes this can one day lead to digital immortality. Grief experts are only now dealing with bereaved people who create digital versions of their loved ones. We look at what...

Coming April 11, 2023, Season 6 of Hi-Phi Nation will look at the future; of work, of love and sex, life and death, our relationship with animals, creativity in music, and philanthropy. Stories include people trying to create digital avatars of dead loved ones, people in exclusive relationships with AI chatbots, animals who are seeking legal protection in courts, the gig economy, AI music, and effective altruism. The episodes will draw out the most interesting moral and philosophical issues...

In our final episode on monsters, we investigate why people who eat people are the funkiest people in the afterlife. We talk to a man who has actually eaten parts of other people, many times, about why he thinks consuming human flesh should be normalized. We then consider the age-old question of how God is supposed to resurrect a cannibal and all of his victims when most of the flesh of the victims would also be a part of the cannibal. Some of the best minds in Western philosophy and...

The second in a three-part series on monsters in philosophy. We trace the cultural history of zombies from voodoo folklore, George Romero films, and the zombies used in philosophical thought experiments. Folklore, film and philosophy seem to converge on the idea that consciousness above all else is what a creature needs to have to be worthy of moral concern, something a zombie lacks. But we have no idea when something crosses over from being a zombie to being conscious, particularly current...

The first in a three-part series on monsters in philosophy. We trace the cultural history of vampires from Eastern European folklore to Twilight, and even look at the practices of real vampires, people who seek out and consume blood or psychic energy. The vampire went from demon to attractive monster in the course of a few centuries and raises a deep question for us about how different we can be, the limits of human imagination, and whether we can ever reasonably choose to have a...

When tragedy strikes an individual, a nation, or an entire people, artists and architects are tasked with designing a public display that memorializes the event and its victims. But how do you do that? In this episode, art historian and podcaster Tamar Avishai examines the Denkmal Memorial to the Murdered Jews of Europe in Berlin, the Vietnam War Memorial in DC, and others to look at how respecting and remembering loss collides with the demands of history and politics. We look at why abstract...

The first two gene-edited species meant to be introduced into the wild are currently in their final stages of approval, with trials already underway for the Oxitec mosquito, and the ESF American Chestnut. In this episode, we examine what these gene-edited species are, what they do, and how they are the beginnings of bio-engineering in the era of massive anthropocentric ecological change. We then look at the ethics of bioengineered wild species and whether they can be the solution to an...

Barry invites Willa Paskin of Slate's Decoder Ring podcast to talk about their recent episode, The Alberta Rat War, as a set up to next week's Hi-Phi Nation episode on genetic engineering. We then proceed to that episode. Rats live wherever people live, with one exception: the Canadian province of Alberta. A rat sighting in Alberta is a major event that mobilizes the local government to identify and eliminate any hint of infestation. Rat sightings makes the local news. Alberta prides itself...

Penny Lane gave up months of wages and weeks of her life to have her kidney cut out and given to someone she never knew, and who may never thank her. She is one of about 200 people in the US a year who give up a kidney altruistically. What motivates someone to do that? Evolutionary psychologist Michael McCullough believes that not only is there true altruism amongst the human species, but that it is a unique trait, an emerging and spreading trait, and it is selected for by evolution, even...

David Lewis steps off a plane from Australia in 2000 and falls seriously ill. In the final year of his life, he decides to take on Christianity, but does not live long enough to write a paper, leaving only his notes. His longtime friend Philip Kitcher turns the notes into Lewis' final piece on the evil of the Christian God. In our final episode of the series, we look at the philosophy of religion and examine the lasting legacy of David Lewis. Guest voices include Steffi Lewis, Ellen Lewis,...

In 1968, David Lewis decides that one truth can unify every theory he's had about the nature of the universe. It is the truth that every possible world is equally real. Lewis not only argues for this view, but devises a distinctive way of arguing for it, a method of doing philosophy that is as influential as his views. Meanwhile, a soon-to-be colleague and rival, Saul Kripke, reads Lewis' paper and fires off eight objections, and on the other side of the world, an entire continent becomes...

What was David Lewis like as a person? The consensus is that he did not know how to converse. At Swarthmore, David Lewis discovers he has a knack for philosophy and none at all with women, leading to a lifelong examination of the norms for conversation. By the time he reaches Harvard, he is ready to meet the love of his life, but almost fails out of the program in the process. By the end of his Harvard days, an entire continent on the other side of the Earth is abuzz about a rising star....

David Lewis was one of the greatest minds of the 20th century, who few outside of academia know much about. By the time of his death in 2001, he was the greatest systematic thinker in metaphysics since the Enlightenment. In Part 1 of a four-part series, we follow his journey from sick little boy in Oberlin, Ohio to teenager learning about free will from Iris Murdoch. We accompany the story of his early life with his theory of time, time travel, and the self. Guest voices include R. Jay...

A woman spends 40 years in and out of prison for shoplifting and finally gets a break from a judge in her late 50s. She uses the opportunity to abolish a jail and transform her city. This week we look at prison abolition and the arguments for eliminating all punishment from the system. From the denial that we have free will, to the view that perpetuating injustice disqualifies the state from punishing, we look at whether any of us have the right to punish anyone else, and question the very...

Two men committed a double murder in rural Maine in 1990. Only one pulled the trigger. The state prosecutor decided to try them separately, but that was a mistake, and both were acquitted. Then the Feds came in, and sentenced one man to life in prison for a crime he was already acquitted of doing. How is this possible in America? The answer is a loophole in criminal law. Today we examine that loophole by looking at the Thanksgiving Day murders in Maine, and the constitutional challenges this...

A teen-aged girl gets caught with a suitcase stuffed with powdered cocaine, and she comes before a federal judge. That judge learns that a felony conviction carries punishments for life for her. He embarks on a mission to get all other judges to shorten prison sentences in light of this. Meanwhile, a researcher learns of a pervasive but secretive practice where prosecutors, defense attorneys, and judges skirt the truth to protect defendants from unjust harsh punishments imposed on them from...

Erick Williams tells the story of how one bad night in the chow hall got him into solitary confinement at Walpole. The path out of solitary, and eventually out of prison, took another decade.  On this episode, we look at the unique power of the Department of Corrections to do with prisoners what they will at their discretion. Philosopher Lisa Guenther tells the history of solitary in America, and the conceptions of the self that drive its continued use. We end with an examination of what the...

On this episode, we look at feminist and progressive prosecution; how does a prosecutor balance the aims of prosecuting more gender-based crimes while also being sensitive to the problems of mass incarceration? We look at the story of one Maine prosecutor who is winning victories in sexual assault cases that were once deemed unwinnable, and whether this lowers the bar of burden of proof to unjust levels for gender crimes. Finally, we look at how one study in 1984 started a 40-year trend in...
