How to rank the impact of innovations on humanity and how much they really changed the world.

Everything seems so important these days:

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

Learn to rationally understand what matters to humanity and what is just noise.

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.

So it's time to build a scale that lets us rationally measure global impact.

Introducing the Innovation Richter Scale - a 1 to 10 rating system that lets you rank absolutely anything you can think of.

NOTE - This episode expands on the Technological Richter Scale proposed by Nate Silver. (see references)

What lies at the core of human progress?

This episode sets the scene for all human innovation. For 3.5 million years, humans and our ancestors were stuck in the Stone Age.

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?

From personal pressures to global forces, we trace the blocks on human development. The answers hold many insights for today when we think about innovation and how to make progress..

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, we are 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. You'll start to connect the dots that are all around you.

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.
