Introduction: The quest to simulate the mind
The human brain, with its complexity and astonishing capabilities, has long been a source of inspiration and challenge for scientists. In an attempt to unlock the secrets of intelligence and consciousness, researchers are turning toward building machines that mimic how the brain works. Recently, China announced a stunning achievement in this field: the creation of a supercomputer modeled after a monkey’s brain, raising questions about the future of artificial intelligence and neuroscience.
Announcement of “Wukong”: A supercomputer with billions of neurons
Researchers at the State Key Laboratory of Brain-Machine Intelligence at Zhejiang University have unveiled their new supercomputer, which they named “Darwin Monkey” or “Wukong,” after the famous legendary monkey.
“Wukong” consists of an artificial neural network comprising more than 2 billion spiking neurons, which replicate biological neurons by communicating via electrical pulses. The supercomputer also includes 100 billion synapses, the connection points that allow neurons to communicate with one another. This massive scale potentially makes “Wukong” the largest neuromorphic computer in the world.
What is neuromorphic computing?
Neuromorphic computing is an approach to computer design that differs radically from traditional computers. Instead of relying on central processing units that execute instructions sequentially, neuromorphic computers mimic the biological circuits of the brain.
The most prominent feature of these machines is their high energy efficiency. While traditional supercomputers consume several megawatts of power (enough to power a small town), “Wukong” can operate on only about 2,000 watts, which is equivalent to the consumption of an ordinary household appliance. This efficiency makes them ideal for advanced artificial intelligence applications that require continuous data processing.
The significance of simulating the macaque brain
Scientists designed their machine to mimic the brain of a macaque monkey, a species frequently used in scientific research because it exhibits human-like intelligence and cognition. Researchers view this achievement as “a step toward more advanced brain-like intelligence.”
Cory Miller, an associate professor of psychology at the University of California, San Diego, says: “Monkeys live a long time and have slow birth rates, just like us. So we can learn a lot of truly fascinating things” by studying them. The first laboratory that manages to create a successful artificial intelligence version of a human-like brain will hold a massive scientific and socio-economic advantage on the global stage.
Potential benefits: A revolution in medicine and artificial intelligence
Knowing how the most delicate parts of our brains work can be invaluable. It could help us understand diseases like Alzheimer’s or cancer, and potentially help us invent life-saving drugs.
Uploading a brain to a supercomputer could significantly accelerate the pace of scientific research. Scientists could run multiple experiments quickly and efficiently without having to wait years to transition from animals to humans for formal approval. This means we could discover the roots of diseases faster and identify cellular or molecular processes that are not functioning correctly, pointing toward drugs and therapies that can alleviate pain and illness more efficiently.
Are we approaching the singularity?
Futurists believe that increasingly advanced neuromorphic computers like “Wukong” could one day lead to the singularity—the hypothetical point where artificial minds surpass human intelligence. However, this concept remains theoretical and controversial, as much remains unknown about human intelligence itself.
Skepticism and challenges surrounding the Chinese achievement
Despite the excitement generated by this announcement, some experts view it with skepticism. Cory Miller points out the difficulty of obtaining real data from China regarding such experiments, saying: “We must take such developments with a heavy dose of caution.”
Furthermore, Miller doubts whether such a supercomputer can produce the information we need to understand the complex brain. Supercomputers are often built in a repetitive manner, and that is not exactly how our brains work. He adds: “Our brains are not a uniform box of synapses. Specialization happens in ways we don’t fully understand.”
Miller emphasizes that while artificial intelligence provides unprecedented opportunities for scientific progress, it will not replace the genuine analytical work that scientists must perform. “The idea that artificial intelligence can replace biomedical research is completely wrong. You cannot fix something if you do not understand how it works.”
