Meta (formerly Facebook) and Spain’s BCBL (Basque Center on Cognition, Brain and Language) are collaborating on a research project called “Brain2Qwerty.” By using noninvasive devices like EEG and MEG, they collect brainwave data while volunteers type on a keyboard, training an AI to predict text based on these signals. Early tests show up to 80% accuracy—especially promising with MEG—though equipm...

I’m traveling with my junior-high daughter, who’s exploring Europe for the firs...

In this episode, we explore the often-heard phrase “If I could overcome it, so can you” and uncover the hidden pitfalls of an overly rigid self-responsibility mindset. While personal effort matters, people’s individual circumstances—financial constraints, health issues, and lack of support—can heavily influence their outcomes. When we overlook these differences, we risk alienating those who need h...

In this episode, we dive into “unnecessarily refined, streamlined yet pointless” concepts—whether it’s a dazzling sports move that doesn’t lead to a score, or sleek glasses with no real function. Far from being mere distractions, these “pointless” creations often spark genuine innovation, especially in a world increasingly driven by AI’s efficiency.

In this episode, we dive into a recent experience my daughter shared: her classmates were happily hanging out until one student left—at which point they instantly began speaking negatively about that person. Disturbed by the sudden shift and anxious that others might talk about her behind her back as well, my daughter came home feeling uneasy. We’ll reflect on this situation through the lens of Yu...
