To run an emulation for 100 subjective years would then require some 10^27 operations.

A typical estimate of the computational requirements for running one emulation is 10^18 operations per second. Alternatively, let us suppose that the computers are used to run human whole brain emulations that live rich and happy lives while interacting with one another in virtual environments. t may take about 10^31-10^44 operations to simulate all neuronal operations that have occurred in the history of life on Earth. “It might not be immediately obvious to some readers why the ability to perform 10^85 computational operations is a big deal.
