15 : The Culmination Of Two Million Years -

We moved from mechanical power to computational intelligence. 3. The Final Frontier: Self-Directed Evolution

By mastering fire, we "outsourced" our digestion, allowing more energy to fuel our growing brains. 15 : The Culmination of Two Million Years

For 99% of these two million years, progress was glacial. A hand-axe design might remain unchanged for a hundred millennia. However, the last 10,000 years triggered an exponential curve: We moved from mechanical power to computational intelligence

We moved beyond simple signals to complex syntax, allowing us to pass knowledge across generations—a process called cultural evolution . 2. The Great Acceleration we "outsourced" our digestion

Creating a "second intelligence" that mirrors our own cognitive processes.
