The Science of Sleep, Creativity, & Dreams | Célia Lacaux (EP 42)

they are more similar than we think?
In this podcast, expect to learn about the study of the rapid transition
period from waking to sleep and its enhanced creativity, how the
science of sleep is changing the way it views sleep by thinking of it as
a continuum rather than a hard line, how parts of our brain may be
asleep during the day (so-called "local sleeps"), the benefits of dreams
and lucid dreaming, and more.

How Falling Populations Will Change The World | Stephen J. Shaw (EP41)
Stephen J. Shaw is a data scientist and demographer, and the creator of
"The BirthGap" documentary.
Fertility rates are below replacement in many countries, and the trend
looks like it will spread to the entire world. This will mean population
levels will fall dramatically in the coming decades. Why is this
happening, what will be the consequences, and can we solve these issues
before it's too late?
In this podcast, expect to learn about Stephen's shock that falling
fertility issues are not being recognized as a problem, how the real
problem is due to a crisis of unplanned childlessness, the biological
reality of when you can have children, how society will have to deal
with the inevitable older and shrinking populations, and more.

Cognition, Consciousness, & The Future of Ai | Maxwell Ramstead (EP41)
Maxwell Ramstead is a cognitive scientist and physicist, and Director of
Research at VERSESAI.

do? What will the future of AI look like? Understanding cognition,
active inference, collective intelligence, and consciousness can help us
find out.
Expect to learn about AI that conducts real-time inference and learning,
how to conceptualize LLMs, why it doesn't make sense to think of
"general intelligence" or AGI, how all intelligence is inherently
collective, about the nature of consciousness and the self, and more...

Cognitive Science of Social Media, Technology, & Meaning | Mark Miller & Ben White (EP 38)
[Re-uploaded podcast with audio at the start fixed]
Mark Miller is a cognitive scientist, and Ben White is currently
completing a PhD in the philosophy of cognitive science.

transforming our lives. How can we understand the profound positive and
negative effects they have? Cognitive science provides a framework to
understand how these technologies influence our minds.
In this podcast, expect to learn about the benefits and harms of social
media, how social media subverts our natural drives, beliefs, and
expectations that typically guide us through the world, how we are
natural-born cyborgs that instinctively embrace technologies, and how we
should think about ourselves and our relationship with technologies in
this context.
