What is the computational limit of biology? According to some technologists, the human brain is capable of 1016 computations per second, and if a super-advanced AI were to ever that threshold (and gain a whole host of other abilities), we’d enter hit what is known in tech circles as the singularity. However, a new article written by theoretical physicist Philip Kurian argues that this limit—and all other neuron-based estimations of life’s computational abilities—have woefully underestimated the true abilities of biological brains.
