IBM has revealed the biggest artificial brain of all time, a simulation run by a 147,456-processor supercomputer that requires millions of watts of electricity and over 150,000 gigabytes of memory.
The brain simulation is a feat for neuroscience and computer processing—but it’s still one-eighty-third the speed of a human brain and is only as large as a cat’s. Will we ever get to truly capable artificial intelligence?
Scientists at IBM’s Almaden research center have built the biggest artificial brain ever—a cell-by-cell simulation of the human visual cortex: 1.6 billion virtual neurons connected by 9 trillion synapses. This computer simulation, as large as a cat’s brain, blows away the previous record—a simulated rat’s brain with 55 million neurons—built by the same team two years ago.
