An ant's brain might contain a quarter of a million neurons, and thousands of synapses per neuron, which suggests that the world's ant brains have a combined complexity similar to that of the world's human brains.
So we shouldn't worry too much about when computers will catch up with us in complexity. After all, we've caught up to ants, and they don't seem too concerned. Sure, we seem like we've taken over the planet, but if I had to bet on which of us would still be around in a million years -- primates, computers, or ants -- I know who I'd pick. (查看原文)

Instead of slowing us down, its tides would accelerate our spin. Quietly, gently, the Moon’s gravity would tug on our planet . . . (查看原文)
