It is not quantum woo and it is not quantum magic. Objective collapse theories are the complete opposite of what you are disparaging. Objective collapse theories are more physical than what we currently have.
Few people have made more contributions in the twentieth century to actual physics than Penrose. He is one of the world's leading experts on general relativity and his objective collapse theory is nothing more that when quantum gravity is understood that gravity will play a role in the collapse of the wavefunction.
To describe Penrose as engaging in 'quantum woo' or 'quantum magic' is grossly inappropriate. It just gives evidence that you don't understand what he is proposing. See Scott Aaronson for what an rebuttal to Penrose looks like not the ham fisted straw man takedowns from the likes of people in this comment section.
- Chronos 9y agoPenrose is not just arguing for objective collapse. Penrose is arguing for something computationally more powerful than objective collapse.
- manyoso 9y agoIf gravity plays a role in wave function collapse that will pose serious questions for the Church-Turing hypothesis. It might very well make it impossible for non-Quantum computers to accurately model quantum gravity. Penrose does not argue for "something computationally more powerful than objective collapse" rather, he argues that the physical Church-Turing thesis is false due to quantum gravity. Something he is an expert on, btw.
