Scientists Try to Duplicate the Wonder of the Human Brain
A 2012 article in Scientific American demonstrates how hard humans will try to copy God's creative power. A team of scientists from around the world are attempting to build a digital version of the human brain—a super-computer that they say will replicate the workings of a human brain. They call it the Human Brain Project. According to Dr. Henry Markram, the lead scientist on the project, the project aims to "reverse engineer" the workings of the brain, beginning with the brains of small mammals and then culminating with the human brain. Dr. Markram claims, "We anticipate that the brain model we develop will have most, if not all, human cognitive capabilities."
But fellow-scientists in the same field have severely criticized the Human Brain Project. First, these scientists argue that we can't possibly replicate the connectivity of the 100 to 500 trillion synapses of an adult brain. Second, they note that the human brain isn't just a static body part. Instead, our brains are constantly changing and growing. Thus, according to one reporter, "Understanding the brain is one thing; making one that can run a virtual human being is a different story altogether." Finally, even Dr. Markram himself concedes that the human brain "is millions of times more powerful than the most powerful supercomputer that exists today." The human brain is also vastly more efficient. If completed, the energy required to run an artificial brain would equal the megawatts needed to run an entire small town in the middle of winter. Our incredibly complex brains hum along on the equivalent of a mere 20 watts of energy—or the energy needed for a small light bulb.
