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.
