Hi creeky belly,

This is absurd, they would most certain couple strongly with the EM force, it would be way more dominant. If you're talking about any type of molecule, it's their electric orbitals which count. And it's waaaaay stronger than gravity. Even the microtubules would be subject to it's coupling effects.

Have you heard of Bucky Balls?  These are miniature soccer balls made up of 60 carbon atoms.  They demonstrate EPR-like effects.  The basic question is, why do Bucky Balls behave differently than normal soccer balls?  Penrose offers it is due to their mass.

By the way, Penrose and Stephen Hawking had a famous debate over this issue in 1994.  While Hawking didn't agree with Penrose, he didn't suggest Penrose's idea was "absurd".  I would be curious as to what Hawking thinks about it today in light of advances in maintaining superposition longer and with larger massed objects.

The Schrödinger's cat paradox refuses to go away by itself.   Penrose's OR quantum interpretation explains it.

Penrose has suggested an experiment named FELIX to test his hypothesis with a tiny mirror.  The mirror is would have just the right mass to be in superposition for the forward going light beam but not for the return.

Pretty much all of them do not last for 100ms, most couple to the environment after anywhere from few pico/femto seconds to a micro second. In addition, all of them require great care in keeping them from coupling when they shouldn't and safety from decoherence. How are the atoms coupled specifically to send information? You don't just get spooky action at a distance, you need a specific interaction to generate it.

You are correct that currently it doesn’t appear we are capable of developing long term quantum memory, yet (we are working on it).  However, we do know the photons can avoid decoherence for years.  I don’t know if any scientific observation like this has been done for cosmic particles other than photons.  Do you know of any?  I will look for them.

Penrose argues against Strong AI.  That is, Penrose argues the human mind can’t be a consistent formal algorithm.  And pseudorandom generators don’t help (they are algorithms).  Here is Planet Math's analysis of it.  Penrose argues that Quantum effects are non-algorithmic and non-random.  Ergo, it is extremely likely the human mind (consciousness) depends on quantum effects.

Whether or not Artificial Intelligence could have been accomplished without quantum effects has probably become a moot point since AI researchers are now designing quantum computers into their systems.
