Disclaimer: I received an advance copy of this book from Basic Books.

I enjoyed Päs's attempt at explaining the important and sometimes misunderstood reality that the universe is fundamentally quantum-mechanical in nature. The first 3 chapters do a marvellous job of taking the reader on a tour of the development of the Copenhagen and many-worlds interpretations of quantum mechanics, with some of the well-known names in the history of the subject making an appearance and with their interactions recounted in an interesting manner. It was the first time that I was brought to reflect a bit more carefully on Everett's many-worlds interpretation.

The detour he takes in the next 2 chapters through the history of the philosophy of monism turned out to be less appealing to me, simply because it is based on much speculation and interpretations that seem to draw parallels between a quantum reality and the impression that everything seems to be coming from a single entity.

In the remaining chapters, Päs delves into relatively recent developments in theoretical physics (black hole entropy, adS/CFT correspondence, EPR=ER, etc.) to try to bring this all together, but I remain quite skeptical about whether the threads that he's so nicely woven throughout his book could be connected via the use of these speculative ideas.

Overall, I found the book an entertaining and quite enlightening tour of many ideas from physics, philosophy (almost exclusively western, unfortunately), and religion, all with the idea of drawing parallels among schools of thought and effectively trying to show how they intersect. What seems to result from this coming together is what the author calls a monistic vision of fundamental reality as a unified whole. Although I remain unconvinced about whether the philosophical concepts have meaningful things to say about physical reality, I would still recommend the book as an interesting appreciation of the unity of physical reality from a theoretical physicist.

As a physicist, I focus my review on the book's interdisciplinary insights and the broader implications of the technological revolutions it discusses.

Metzl's book is a compelling exploration of the rapid advancements in AI, genome sequencing, and biotech, and how their intersection is poised to redefine various aspects of our existence. His concept of “superconvergence” captures the essence of how these technological streams are not merely progressing in parallel but are increasingly intertwined, leading to exponential changes in our capabilities and societal structures.

From a theoretical perspective, Metzl's discussions on AI are particularly intriguing. He delves into how ML algorithms and neural networks are evolving, drawing parallels to complex systems theory. The potential of AI to augment human intelligence aligns with theories in quantum computing and the limits of computational capacity. His arguments resonate with the notion of a technological singularity, a point where AI surpasses human intelligence, which has been a topic of speculation and debate.

Metzl also touches on the implications of genome sequencing and gene editing. The CRISPR-Cas9 technology, which he highlights, can be likened to manipulating a complex system with a precise mathematical model. The precision of gene editing and its potential to eradicate genetic diseases or enhance human capabilities draw a fascinating parallel to control theory in physics, where the goal is to influence the behaviour of dynamic systems.

The ethical considerations Metzl raises are deeply rooted in the philosophical aspects of science. He questions how society will manage these godlike powers responsibly, a theme that echoes the moral quandaries faced in nuclear physics during the development of atomic energy. This intersection of ethics and technology is critical, as it underscores the need for a framework that guides the responsible deployment of these advancements.

Furthermore, Metzl's analysis of how these technologies can impact global health, the economy, and environmental sustainability provides a systems-level understanding of the interconnectedness of technological progress and societal well-being. His integration of historical, political, and international affairs perspectives enriches the narrative, making it a comprehensive guide to understanding the future landscape shaped by superconvergence.

In summary, “Superconvergence” is a thought-provoking read that effectively bridges multiple disciplines. For a physicist, it offers a fascinating glimpse into how technological revolutions can be understood through the lens of complex systems, control theory, and ethical considerations, all while emphasising the need for proactive and responsible management of these powerful tools. Metzl's work is an essential contribution to the discourse on the future of technology and its profound implications for humanity.

I approached “Why Machines Learn” with an appreciation for the intricate dance between theoretical concepts and their practical applications. It delves deeply into the mathematical frameworks that have driven the remarkable advancements in ML and AI.

Ananthaswamy excels in breaking down complex mathematical ideas into digestible segments. From Rosenblatt's perceptrons to contemporary deep neural networks, the book navigates through decades of developments with clarity. The author's ability to explain linear algebra, calculus, and other foundational mathematical concepts is commendable, making these subjects accessible even to those without an extensive background in mathematics. This is crucial for a broader audience to appreciate the profound implications of these algorithms.

What I found to be one of the book's strongest points is its integration of the social and historical contexts within which these mathematical advancements occurred. By weaving narratives of key figures in AI, such as Geoffrey Hinton and others, Ananthaswamy provides a richer, more nuanced understanding of how these technologies evolved. This approach not only humanises the scientific endeavour but also highlights the collaborative nature of scientific progress.

The book does not shy away from discussing the real-world applications and ethical dilemmas posed by ML systems. Ananthaswamy explores how these algorithms impact critical areas like medical diagnostics, financial decisions, and criminal justice, prompting readers to consider both the capabilities and the limitations of AI. This balanced perspective is essential in an era where AI is increasingly intertwined with everyday life.

While “Why Machines Learn” is highly informative, there are areas where it could delve deeper. For instance, the mathematical discussions, while clear, sometimes gloss over the more intricate proofs and derivations that a mathematically sophisticated audience might crave. Including appendices or supplementary sections with detailed mathematical treatments could enhance the book's appeal to a technically proficient readership.

Additionally, the book could benefit from a more thorough exploration of cutting-edge topics such as quantum ML and the implications of AI for theoretical physics. Given the rapid pace of advancements in AI, a forward-looking chapter on speculative developments and future trends would have been a valuable addition.

This was my first book read on understanding how to run an early-childhood outdoor programme. It's a useful resource, full of insight about what considerations go into designing an outdoor education programme, and brimming with ideas of planned activities. I lok forward to supplementing it with other book guides.
