The AI Dilemma

Juliette Powell & Art Kleiner Berrett-Koehler (2023)

The benefits and harms of social media are intimately tied to the ongoing debate about artificial intelligence (AI). Will AI systems trained partly on social media benefit or harm humanity? In their excellent, sometimes alarming, analysis of engineering, social justice, commerce and government, entrepreneur and technologist Juliette Powell and writer and educator Art Kleiner compare humans developing AI tools to first-time parents. They recommend guiding AI systems “as we would a child towards full adulthood”.

Consciousness

John Parrington Icon (2023)

“The material basis of human consciousness is one of the biggest unsolved issues in science,” admits cellular and molecular pharmacologist John Parrington in his pithy addition to a vast literature dating from the time of ancient Greek philosopher Aristotle. He considers many theories and proposes his own. Humans, he argues, are distinguished by conceptual thought and language, along with skills in designing tools and technologies. The evolution of these powers transformed our brains, creating meaning and consciousness.

Democracy in a Hotter Time

Ed. David W. Orr MIT Press (2023)

Environmentalist David Orr writes in the introduction to this timely collection that the planet faces two interlinked crises: “rapid climate change and potentially lethal threats to democracy”. The US Constitution rigorously protects private property but does not mention ecological systems, he observes. Contributors — almost all US-based — from a wide range of fields examine the need for political reform. The book is in four parts: the nature of democracy; roadblocks to change; policy and law; and education, including academic culture.

Extinctions

Michael J. Benton Thames & Hudson (2023)

When palaeontologist Michael Benton learnt about dinosaurs as a boy, he “loved the fact they were extinct”. They were like real science fiction. Perhaps he also intuited that their extinction permitted his existence. As his deeply informed and readable book reveals, the mass extinction at the end of the Cretaceous period 66 million years ago allowed a new cohort of creatures — including mammals — to “inherit the Earth”, as did four earlier extinction events. Living species represent less than 1% of all the species that have existed.

A Guess at the Riddle

David Z. Albert Harvard Univ. Press (2023)

The physical interpretation of quantum mechanics has been a controversial riddle since the 1920s, when Niels Bohr argued that the atom’s inner workings could not be described in physical terms. Today, many philosophers and physicists disagree, but there’s no consensus on an alternative. Philosopher David Albert’s provocative book argues, in three essays, that Bohr’s quantum-measurement problem starts to make sense if the wave function is understood as the fundamental physical ‘stuff’ of the Universe.
