Creative thought is surely among our most precious and mysterious capabilities. But can powerful computers rival the human brain? As thinking, remembering and innovating become increasingly interwoven with technological advances, what are we capable of? What do we lose? Join Luciano Floridi, John Donoghue, Gary Small and Rosalind Picard for a thought-provoking program about thinking.

This program is part of The Big Idea Series, made possible with support from the John Templeton Foundation.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

In the midst of the heated debate about AI sentience, conscious machines and artificial general intelligence, Yann LeCun, Chief AI Scientist at Meta, published a blueprint for creating “autonomous machine intelligence.”

LeCun has compiled his ideas in a paper that draws inspiration from progress in machine learning, robotics, neuroscience and cognitive science. He lays out a roadmap for creating AI that can model and understand the world, reason and plan to do tasks on different timescales.

While the paper is not a scholarly document, it provides a very interesting framework for thinking about the different pieces needed to replicate animal and human intelligence. It also shows how the mindset of LeCun, an award-winning pioneer of deep learning, has changed and why he thinks current approaches to AI will not get us to human-level AI.

We often worry about the possibility of a civilization developing methods of brainwashing to indoctrinate its population and turning into a totalitarian dictatorship. We will examine both existing and possible future methods and technologies for mind control, such as neuro-hacking and genetic programming, as well as the possible defenses against such brainwashing or conditioning and implications it has for civilization.

A look at how emerging concepts in science & technology could disrupt our most our understandings of identity, consciousness, and free will. This is the 5th episode of the Existential Crisis series which looks at concepts like Transhumanism, Life Extension, the Simulation Hypothesis, the Doomsday Argument, and the Anthropic Principle.

We continue our discussion of the Boltzmann Brain — a hypothetical randomly assembled mind rather than an evolved one — by looking at the Anthropic Principle and the Fine-Tuned Universe Theory, alternative ways of viewing the probability of our existence than the classic Copernican Principle.

Summary: Cognitive immobility is a form of mental entrapment that leads to conscious or unconscious efforts to recreate past instances in familiar locations.

Source: The Conversation.

If you have moved from one country to another, you may have left something behind – be it a relationship, a home, a feeling of safety or a sense of belonging. Because of this, you will continually reconstruct mental simulations of scenes, smells, sounds and sights from those places – sometimes causing stressful feelings and anxiety.

You use your brain’s executive function every day — it’s how you do things like pay attention, plan ahead and control impulses. Can you improve it to change for the better? With highlights from her research on child development, cognitive scientist Sabine Doebel explores the factors that affect executive function — and how you can use it to break bad habits and achieve your goals.

A recent study indicates the prevalence of brain changes from limbic-predominant age-related TDP-43 encephalopathy might be approximately 40% in older adults and as high as 50% in people with Alzheimer’s.

Alzheimer’s disease is a disease that attacks the brain, causing a decline in mental ability that worsens over time. It is the most common form of dementia and accounts for 60 to 80 percent of dementia cases. There is no current cure for Alzheimer’s disease, but there are medications that can help ease the symptoms.
