Peter Singer: Are we prepared for AI to become conscious?
lundi 6 octobre 2025 • Durée 06:27
"If we did create beings that were more like non-human animals, we ought to treat them much better than we now treat non-human animals."
What happens when AI becomes conscious? Philosopher Peter Singer explores the ethical dilemma that could follow the creation of sentient machines. If AI can feel pain or experience pleasure, do we have a moral obligation to protect it?
Singer argues that governments, scientists, and ethicists must prepare now for the rights and protections conscious AI may require.

10 biggest world threats of 2025, ranked | Ian Bremmer
vendredi 24 octobre 2025 • Durée 29:23
"There is so much more uncertainty and volatility in a world that is moving fast with big countries that are more at odds with each other and with fewer rules of the road that leaders, companies, and societies are adhering to."
Ian Bremmer, president of Eurasia Group and GZERO Media, has been delivering his insightful Top Risks Report for 15 years. The primary objective? To systematically outline how we should approach the world's most significant threats and opportunities in any given year.Bremmer's Top Risks report stands in stark contrast to the clickbait and anger-inducing algorithmic news dominating social platforms. Rather than succumbing to sensationalism, the report serves as a rallying point for professionals and the wider public to focus on what truly matters for global success. It navigates the realm of reality, steering away from ideology and personal biases."The G-Zero world and America first are working together in lockstep, and that means more ungoverned spaces, more rogue actors, more geopolitical instability and more conflict. That's where we're heading in 2025." Here, Bremmer presents his top 10 risks demanding our attention and preparation in the year 2025.

Michio Kaku: Quantum computing is the next revolution
lundi 6 octobre 2025 • Durée 15:17
"We're now in the initial stages of the next revolution."
Dr. Michio Kaku, the renowned theoretical physicist, walks through the evolutionary journey of quantum computing, from analog to digital to the quantum era. Quantum computers hold immense promise because of their ability to tap into parallel universes, which boosts their computational power exponentially. They could revolutionize agriculture, energy, and medicine, solving complex problems like creating efficient fertilizers, achieving fusion energy, and modeling diseases at the molecular level.
The race between major tech companies and intelligence agencies to actualize this power is intense, as they could redefine industries and even global power structures if they succeed.
The endeavor isn’t without challenges; we’ve yet to create a fully functional quantum computer. But Kaku envisions a future where quantum computers unravel complex equations, potentially shedding light on profound cosmic mysteries.

The “afterlife” according to Einstein’s special relativity | Sabine Hossenfelder
vendredi 7 novembre 2025 • Durée 13:41
Sabine Hossenfelder investigates life's big questions through the lens of physics, particularly Einstein's theory of special relativity. She highlights the relativity of simultaneity, which states that the notion of "now" is subjective and dependent on the observer. This leads to the block universe concept, where past, present, and future all exist simultaneously, making the past just as real as the present.
Hossenfelder also emphasizes that the fundamental laws of nature preserve information rather than destroy it. Although information about a deceased person disperses, it remains an integral part of the universe. This idea of timeless existence, derived from the study of fundamental physics, offers profound spiritual insights that can be difficult to internalize in our everyday lives. As a result, Hossenfelder encourages people to trust the scientific method and accept the profound implications of these discoveries, which may reshape our understanding of life and existence.
As a physicist, Hossenfelder trusts the knowledge gained through the scientific method and acknowledges the challenge of integrating these deep insights into our daily experiences. By contemplating these profound concepts, we can potentially expand our understanding of reality and our place within it.

A neuroscientist’s guide to reclaiming your brain | Nicole Vignola
lundi 3 novembre 2025 • Durée 09:24
**Are you trapped in a narrative that isn’t really yours?** From childhood, we absorb beliefs about who we are—“the smart one,” “the creative one,” “the failure.” These labels, shaped by family and environment, become our **Perception Box**, limiting what we believe is possible. But neuroscience reveals that we can rewrite our stories. By recognizing negative thought patterns, questioning old identities, and celebrating small wins, we can **rewire our brains** and reshape our reality. **So, who do you really want to be?**
Your brain is wired to repeat the familiar. Change this wiring, and it will change your life.
Nicole Vignola, a neuroscientist and organizational psychologist, explains how deeply rooted beliefs can limit our potential and keep us trapped in patterns of thought. These perceptions, often shaped by our upbringing and environment, aren’t necessarily our own—but they can be changed.Nicole shares how the brain’s natural biases, like negativity bias and confirmation bias, reinforce these limiting beliefs. However, with the right approach, it’s possible to reshape our mental patterns. By practicing metacognition—observing and naming our thoughts—we can start to rewire our perception and create new, empowering narratives.Our brains are capable of change at any age. By focusing on small wins and challenging automatic thoughts, we can break free from old beliefs and begin using a mindset that better serves ourselves and our futures.
About Nicole Vignola:Nicole Vignola is a neuroscientist, author and corporate consultant. With a BSc in Neuroscience and an MSc in Organizational Psychology, Nicole works with companies and individuals worldwide, educating them on the science of human optimisation, health and longevity, and how to enable employees to perform better in their daily lives and in turn, bring peak performance to the workplace. Recent clients include Lloyds Bank, Makers Mark and Smeg Ltd.

I help people die – here’s what they’ve taught me about living | Alua Arthur
lundi 3 novembre 2025 • Durée 10:03
“I want people to know that their lives matter and that their deaths ultimately will too.” How a journey to Cuba made Alua Arthur confront her own mortality, and ultimately led her to her career as a death doula.
Alua Arthur, a death doula, never expected to find her calling in the space between life and death. Struggling with depression and a sense of not belonging, she was searching for meaning when a chance encounter in Cuba changed everything. After encountering death in her personal life, she began to confront her own mortality—and realize she wasn’t truly living. This moment, combined with the loss of her brother-in-law, set her on a path to becoming a death doula, someone who supports people through their final days. Now, she is an author, a (public speaker), and has dedicated her career to helping others embrace life by acknowledging its inevitable end.
Alua Arthur, a death doula, shares her journey from feeling like an outsider to finding purpose in helping others face death with grace. She describes struggling with depression while working as a lawyer, feeling disconnected from life. A transformative conversation with a terminally ill woman in Cuba made her confront her own mortality and realize the importance of truly living.
When her brother-in-law fell ill and passed away, it deepened her understanding of life and death. She then chose to become a death doula—providing emotional and logistical support to the dying and their loved ones. Through this work, she has learned to live with urgency, be fully present, and embrace herself as she is.
Key Takeaways:
Facing death helps clarify what truly matters in life.
Living fully means embracing every moment without holding back.
Supporting people in their final moments can be a deeply healing and meaningful role.
About Alua Arthur: Alua Arthur is a death doula, end-of-life care expert, and founder of Going with Grace, a nonprofit dedicated to helping individuals navigate the final chapter of their lives. After struggling with depression and identity, Alua found purpose in guiding others through the dying process with compassion and dignity. She has dedicated her life to empowering people to face death with grace, offering support to both individuals and their families.

You have no free will at all | Stanford professor Robert Sapolsky
lundi 6 octobre 2025 • Durée 01:00:34
How your biology and environment make your decisions for you, according to Dr. Robert Sapolsky.
Robert Sapolsky, PhD is an author, researcher, and professor of biology, neurology, and neurosurgery at Stanford University. In this interview with Big Think’s Editor-in-Chief, Robert Chapman Smith, Sapolsky discusses the content of his most recent book, “Determined: The Science of Life Without Free Will.”
Being held as a child, growing up in a collectivist culture, or experiencing any sort of brain trauma – among hundreds of other things – can shape your internal biases and ultimately influence the decisions you make. This, explains Sapolsky, means that free will is not – and never has been – real. Even physiological factors like hunger can discreetly influence decision making, as discovered in a study that found judges were more likely to grant parole after they had eaten.
This insight is key for interpreting human behavior, helping not only scientists but those who aim to evolve education systems, mental health research, and even policy making.

About Robert Sapolsky:
Robert M. Sapolsky holds degrees from Harvard and Rockefeller Universities and is currently a Professor of Biology and Neurology at Stanford University and a Research Associate with the Institute of Primate Research, National Museums of Kenya.
