This is far from obvious. Brains are large but finite. They contain around 100 billion neurons with around 1,000 connections (or synapses) each. On current estimates, the brain performs the equivalent of around 10 quadrillion (1016) floating point operations per second (or flops): a computing speed also known as 10 petaflops. That’s a lot, but it’s about on a par with the best existing supercomputers.
