Whether it's the funds-fueling AI or crypto's trillion-dollar swings,

there's a money-side to every story.

And when you see the money-side, you understand what others miss.

Are humans inherently selfish?

We've covered research on this very show that says otherwise.

But looking at the realities of wealth disparity, wars fought over fuel,

and casual overconsumption as the planet burns,

it can certainly feel like our species must be somehow rotten at its core.

Our guest today has a different perspective.

Author Jeremy Lent is the founder of the Deep Transformation Network,

a global online community geared toward creating a better future for humanity.

He argues that while our society's current systems are exploitative and destructive,

the natural state of humanity and of the planet we live on is one of mutuality and shared abundance.

His latest book, Eco-Civilization, is a deeply researched manifesto on the inevitable failure of our entrenched systems, as well as a

roadmap for a radically sustainable vision for humanity's next chapter. Thank you so much for coming

on to chat with us. You're welcome. Looking forward to Maritle. So tell me a little bit about your new book.

You say you aim to change the operating system of the entire world.
