Human brain FLOPS

$$ \begin{align*} \text{neurons} &= 10^{11} \\ \text{synapses/neuron} &= 10^3 \\ \text{synapse freq} &\approx \text{500 HZ} \\ \therefore \text{no.\ of\ brain\ FLOPS} &\approx 10^{16} \end{align*} $$

Total computer operations to simulate all brain FLOPS

It is difficult to estimate the population & duration of the simulation, as it is contextual. But we can assume a relative upper-bound to gauge pessimistic estimates.

$$ \begin{align*} &\bm {simulation\ parameters} \\ & \text{population} = 10^{10} \ \text{people}\\ & \text{duration} = 10^{10}\text{s (}\sim \text{300 years)} \\ \end{align*} $$

$$ \bold {total\ computational\ operations \approx 10^{36}} \\ OR\\ \sim \bold{10^{26}\ operations/s} $$
