How to Change the World: The History of Invention

Innovations have huge impacts on humanity. But which ideas matter the most?

Sam W. Harris builds out a system to rank world change and compare the impact of technology and inventions.

It's easy to tell that the invention of Writing itself is more important than Velcro. But...

• Is Netflix more important than Baseball?
• Has TikTok changed the world as much as the Longbow?
• Was Steve Jobs more impactful than Henry VIII?

History has opinions. It's time to sense check what matters to humanity and the future and what is just noise.

Headlines are beyond useless when everything seems so important these days:

• This war will BREAK the economy
• If you feed your toddler THIS, you don't deserve to be a parent
• A new iPhone update changes EVERYTHING...

So it's time for a scale to measure global impact.

The Innovation Richter Scale: A 1 to 10 rating system to rank anything you can think of; from a Gillete safety razor to the future of AI

NOTE - This episode expands on the Technological Richter Scale proposed by Nate Silver.

ABOUT

What lies at the core of human progress? This episode asks ancient history what created human innovation and what stopped it for so long?

For 3.5 million years, humans and our ancestors were stuck in the Stone Age until 10,000 years ago we finally broke out of it and all manner of inventions was let loose.

We study tribal life across the world from anthropological records and archeology of the stone age to reconstruct the lifestyle of our ancestors and the forces against them. From personal pressures to global currents, we trace the blocks on human development. The answers hold many insights for today when we think about innovation, technology and how to make progress..

We cover:

• What were we busy with for 97% of our existence?
• Why were we so slow at innovating?
• How did we eventually overcome these fundamental forces?

This episode is ground zero as we begin our expedition through history and the creation of our modern world.

"The only way to make sense out of change is to plunge into it" - Alan Watts

This opening episode invites you on a journey, not just through time, but through perspective.

From fire-starting hominids to spacefaring technologists, "How to Change the World" is going to trace the ripples of human imagination that turned tools into empires, and sparks into systems.

In this introduction episode:

• Set the tone for the podcast
• Explain what the show is and isn't
• Learn how we are going to navigate this journey
• Answer who the hell is this 'Sam Harris' (the host)
• Explain our 7 principles for exploring history and innovation

Change is rarely neat or obvious, but this podcast is here to help us understand it. We connect dots in history from the cognitive revolution and invention of language to the future of AI. Learn to ask better questions and consider the existential patterns of humanity and where we're going next.

History isn't just a study of the past, it is also our present. As we live through unprecedented innovation, it's a perfect time to study the forces of tectonic shifts and how to guide them.

If you're curious, optimistic, and even a little lost. You're in the right place.
