[~1.8 Mya] - Fire: The Innovation that Forged Humanity and Sparked World Domination

Do we really control fire?

While you're patting yourself on the back for lighting that barbecue, fire has been pulling the strings for 2 million years, reshaping our anatomy, rewiring our brains, and dictating our social structures.

It transformed us from ape-like creatures that had a neat standing trick into the cunning apex predator of the world. Along the way, it upended both ecosystems and gender roles but most importantly, made us human.

The lesser-known of fire is that an individual human is completely dependent on it to survive. Furthermore, Society itself is built on fire and would collapse totally without it

Today, as we face the dawn of AI, we're seeing the same pattern. Fire marked a huge leverage of energy that freed us up to think. AI promises to do our thinking for us, which frees us up for who knows what.

aren't tools we use; they're partners that reshape us from the inside out.

Three takeaways:

• Transformative technologies change what we are, not just what we do
• Dependency often disguises itself as control and mastery
• The biggest innovations create irreversible psychological and social shifts
