Technology continues to improve the lives of humans. See how technology has changed the lives of our ancestors, from low life expectancy and lives of drudgery to the highest life expectancy with leisure taking most of our time. Topics will include advances in language and communication, agriculture, transportation, energy, medicine, and more. How did humans manage to go from hunting and gathering feeding a very small population in good times, to feeding 7.5 billion people and their animals. Follow humans wandering and dragging belongings, to the discovery of the wheel, seafairing, and mechanical machinery allowing for rapid movement. Follow the stages of computer improvements starting with the origins of math to abacus to days computers in our pockets plus details on social media and AI! At the end of the class we’ll vote for the most meaningful technology that has impacted all of us.  The class will be lectures and discussion, with little prep time.
