    10 Important Differences Between Brains and Computers


Nowadays we not regard to brain is very the best machine in the world. People know just brain is humans controller and it make people's emotion. Also, only human have the brain. However, we usually forget perhaps the most amazing brain's abilities we all have. Maybe human knew computers are help for human brains so computers are more cleaver than human brains. However, think about the human brain in detail, it has more


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.

Since Samuel Butler first expressed his fears of the rapid development of machinery, humans have fixated on this imagined future where we are enslaved or worse by our own creations. Considering he said, "There is no security against the ultimate development of mechanical consciousness," in 1906, before computers, his words proved surprisingly salient (Butler, 1906). Despite the fact that computers are indisputably growing in terms of computational power at an incredible rate (Moore, 1998), there is no reason to realistically fear a computer that can work autonomously in any meaningful way, let alone outsmart a human. Consider Microsoft's Project Adam. The software can sort and organize millions of photos quickly and accurately by analyzing the images. It can distinguish between extremely similar looking breeds of dogs in a photo, for example (Microsoft Research, 2014). Practically this means you might one day be able to do an image search for a sweater you want, oh, say, "a mauve cashmere sweater with 3/4 lengths sleeves," and without any cumbersome text based tagging or sorting the search engine will analyze every single image on the internet and parse out all the cashmere sweaters that aren't mauve or have full sleeves. An impressive accomplishment. This represents one of the most incredible achievements of practical computing today. However, even this breakthrough in computing technology does nothing to narrow the gap between computer and human intelligence. The technology cannot operate independently of human involvement. The technology is still responding entirely to human based input, on human based instructions with human programmers and human technology feeding it, like electricity or data from the internet.
