Not so simulated

March 16, 2017

Sabine Hossenfelder takes issue with Nick Bostrom’s argument that we might live in a simulated universe, based on the difficulty of simulating the current laws of physics. Bostrom’s core argument is that our descendants a) will have almost unimaginable computing resources, b) so vast that the simulation of universes such as our own is possible, c) they will create such simulations, so d) our own universe might be one such. Hossenfelder is criticizing b). I find c) quite speculative. Bostrom handwaves what human (or transhuman) effort might be required to reach that goal. Just because there is the computing power to do something doesn’t mean it is a practical or desirable exercise.
