The emulations would not have to be uploads of specific human brains, nor would they need to be running in real-time.

A working definition of a human brain emulation could be a computer program that:

1. Can perform any cognitive task at a standard equal or greater than the 10th percentile of the global biological human population

2. Can consistently pass a strong adversarial Turing test

3. Is known to have its cognition emerge entirely from internal structures and rules analogous to that of biological human brains down to the neuron level
