No free lunch. Hashlife takes more memory and only works well in low entropy environments.

But, consider if you want to run a simulation 100 times using the same data you can speed that output up by just copying the output of the first simulation 100 times. But that's not simulating the same mind 100 times it's simulating the mind only once. Hash life and similar approaches don't increase your ability to compute unique mind states.
