Everyday we marvel at the power of our tiny computing devices - a phone that knows if it is in a purse or not, a watch that tracks your calendar, or shoes that help you exercise optimally by measuring your heart rate. However, we usually forget perhaps the most amazing computing device we all have - our brains. Perhaps computers can beat the brain in certain, limited computational tasks, but the overall performance of the brain out-performs every man made object to date. Think about it - Your brain keeps you balanced while you walk, helps you decide when and what to eat, regulates your emotions and allows for all art and culture ever produced. Actually, you couldn't even think about this without your brain, a task no computer could accomplish. Although computers are constantly evolving, they will never be as powerful as the human brain.
1. Attention grabber -
I attracted the audience by describing a familiar situation to them, commonplace and powerful technology. Then I pointed out something most of them forget - they themselves are actually incredible computational powerhouses.
2. Explains the topic -
In the attention grabber I introduce all the elements of my topic: Human computational power, computer computational power, and the comparison of the two.
3. My thesis -
It is clear, direct and an argument. I thought the argument "Human brains are more powerful than computers" was too simple and nobody would dispute it. I changed it to a better argument, computers will NEVER be as powerful as the human brain.
