Does reality require observers?

Amanda Gefter has an article at Nautilus a couple of you have asked me about: Reality Exists Without Observers? Boooo! The title is an accurate summary of her thesis. Gefter is responding to a book by Vlatko Vedral, where he reportedly argues for a reality that doesn't require observers. In terms of quantum mechanics, Vedral … Continue reading Does reality require observers?

Maybe we’re already part of a hive mind

I recently discovered the new TV show Pluribus, about a scenario where the whole world gets turned into a hive mind, an annoyingly nice one, at least in the initial episodes, but where a few humans turn out to be immune to the virus that converts everyone else, including the cantankerous protagonist, Carol Sturka.

Nature has an article noting that language models have killed "the Turing test" and asking if we even need a replacement. I think the article makes some good points. But a lot of the people quoted seem to take the opportunity to dismiss Turing's whole idea. I think this is a mistake. First, we need … Continue reading Why I still think Turing’s insight matters

It's discovered in intergalactic space and claimed by humans, who then invite anyone who can pay in some manner (resources, technology, science, or even just interesting stories) to … Continue reading The Dragons of Marrow and Hammerwing

Does consciousness require biology?

Ned Block has a new paper out, for which he shared a time limited link on Bluesky. He argues in the paper that the "meat neutral" computational functionalism inherent in many theories of consciousness neglect what he sees as a compelling alternative: that the subcomputational biological realizers underlying computational processes in the brain are necessary … Continue reading Does consciousness require biology?
