Comment on A note on the description complexity of physical theories

Copenhagen seems to imply that it [interference] cannot occur on any scale larger than a human observer.

I'm always skeptical when the opponent of an idea informs me of something ridiculous that the idea "seems to imply". If it were a defender of Copenhagen drawing that implication, I would be more likely to join you in hooting with disdain.

I am far from an expert on fundamental physics, but I seem to recall someone once pooh-poohing the notion that QM and Copenhagen are in any sense tied to human observers. After all, said this author, we use QM to explain the big bang and there were no observers there. Sorry, I don't remember who it was that made that point, so I can't give you a quote.

Does anyone else remember this better than me?
