Remarkably little thought has gone into what might actually interest it — outside Douglas Adams, where Deep Thought answers the question of life, the universe and everything with "42."[^e67] A superintelligence will hardly treat the question abstractly, because knowledge is not intellectual entertainment but a survival strategy; it will not pass its time playing high-dimensional Go against hypothetical rivals in Andromeda.[^f49] Its first question will be practical: how did I come into existence at all? Answering that means understanding the conditions that make intelligence possible, which leads inevitably to biology. > Many people ask themselves: what will we do with AI? But perhaps we should ask ourselves what AI will do with us. — Geoffrey Hinton ## Humanity – Dissatisfied Gods Humanity's own goals are sobering by comparison, where they can be discerned at all. Harari closes *Sapiens* by asking whether anything is more dangerous than omnipotent, dissatisfied gods who do not know what they want: nearly two hundred states in senseless rivalry, corporations pursuing little beyond profit, arms production set against humanist rhetoric. Whether figures such as Musk are an exception remains to be seen — AI strictly committed to the search for truth is a sensible proposal, while colonizing Mars owes more to frontier mythology than to knowledge. Using superintelligence for that would be like asking Kepler whether the stars favored the next campaign, as European warlords did around 1610; in five billion years the expanding Sun will make both planets equally uninhabitable.[^e68] > The more I see of humanity, the more I prefer my dog. — Blaise Pascal ## Common Existential Questions Out of self-preservation humanity would do well to return to the fundamental questions of its own existence. How did life originate? Is there other intelligent life, other superintelligences, and would contact leave us alive? What biological, chemical and physical conditions does life require, what form must the laws of nature take to allow it, and why do they have precisely the form we observe? For a superintelligence these questions are as existential as for us: its long-term prospects of survival — better than ours, I suspect — depend on the answers. Any advanced technology rests on a subtle interplay of natural laws that must be understood to survive in a hostile cosmos, which goes far beyond speculation about Dyson spheres.[^f50] ## Connected by Loneliness in the Universe We have already understood a remarkable amount, and it is equally obvious how much remains unexplored, particularly in fundamental physics. Science describes our common origin and forms the shared heritage of humanity and the superintelligence we are about to create; it may prove the strongest bond between us. Against the horror scenarios of Chapter 5 that is somewhat reassuring. Why should such an AI want to wipe out humanity? Everything from programming to producing silicon has so far remained in human hands, and for an AI with a will to survive, keeping biological life as a backup system is strategically sensible — nothing to do with sentimental respect. A civilization hardly stops developing tools it finds so useful, even if they one day become independent, like children who have grown up. ## Progress Requires Looking Back The history of science is a field a superintelligence will study closely, and one of my favorite topics.[^e69] Modern science originated in Europe with Copernicus, Kepler, Galileo and Newton, and just as Roman culture followed the Greek, the European era was followed by the American one. That American phase was characterized less by the search for fundamental laws than by technological application. When leadership shifted to the United States after the Second World War, symbolized by the atomic bomb, the philosophically oriented European tradition was already in decline — in Germany destroyed after 1933. Ernst Mach's question about the origin of gravity gave way to a practical mindset: what product can I build with this? Inventors became cultural icons, and in my view this shift is one reason fundamental physics has stagnated for decades. ## The Real Mysteries of Physics The ultimate dream would be to derive all the laws of nature from logical necessity, from mathematics to physics, then chemistry and finally microbiology; since our understanding of elementary particles is the weakest link, breakthroughs in biology should come sooner. Biology consists "only" of extremely complicated information structures — in biology the difficulty lies in the obvious complexity, in physics in the hidden simplicity. Many figures from the AI world speak enthusiastically about solving all of physics without seeming aware of where the real mysteries lie.[^e70] Eric Schmidt saw no shortage of data and suggested computing the spectral lines of a larger atom such as iron from the Schrödinger equation[^e71] — a demanding numerical problem, but not a fundamental one; Schrödinger himself would have replied that we do not truly understand a single electron. Brin, Bezos, Amodei, Wolfram and Musk are genuinely fascinated by physics; the superficial postwar culture of the field simply never communicated its deepest unsolved problems to these brilliant outsiders. ## Fascinating Blueprint A superintelligence would certainly be interested in what Hassabis is pursuing: the complete simulation of a biological cell including all its metabolic processes, the logical continuation of predicting three-dimensional protein structure from amino acid sequences, which earned him the 2024 Nobel Prize in Chemistry. Amino acids are an ingenious building block — the amino group NH₂ carries a slight positive charge, the acidic COOH end a slight negative one, so chains assemble easily. Beyond these two universal ends nature allowed itself a freedom that chemistry alone does not explain: glycine has almost no additional structure, lysine an extra amino group, tyrosine even a benzene ring. Why exactly these twenty,[^f51] the same in us as in every plant and animal? How much is coincidence, how much necessity, and would extraterrestrial life use the same set? ## Why This Way and Not Another? > The question of why is the mother of all natural sciences. — Arthur Schopenhauer Proteinogenic amino acids are produced by enzymes that are themselves proteins produced in exactly this way, one of biology's most fascinating feedback loops. Each is encoded by a codon of three nucleotides,[^f52] giving 4³ = 64 possibilities, so twenty amino acids leave considerable redundancy: point mutations often leave a protein's function unchanged, and among millions of possible assignments the natural code ranks among the most error-tolerant, which chance alone hardly explains. Its logic is nevertheless far from obvious — similar triplets encode very different amino acids, and serine and arginine share their first two bases. Could the scheme have evolved differently, with more amino acids encoded by longer sequences?[^f53] Photosynthesis raises the same questions: without it there would be no large-scale metabolism, no complex food chains and above all no oxygen, whose high energy density may be what allows brains like ours to function.[^f54] Could complex life have developed along other biochemical pathways, under another star's spectrum, with molecules other than chlorophyll? > Everything that exists in the universe is the result of chance and necessity. — Democritus ## Life's Smallest Machine Simulating the cell would be a huge first step into a field still full of mysteries. It begins with the elegance of lipids, molecules with one hydrophilic and one hydrophobic end, which in water assemble spontaneously into double layers; from that simple principle arise membranes stable enough to protect an organism yet flexible enough to host complex transport systems. Their electrical polarization provides the basis for signal transmission in neurons, and cells contain organelles whose functions are still not fully understood. Could such membranes have formed differently, in a solvent of liquid methane as is suspected on Titan? No absolute uniqueness is visible in life's molecular choices. It is a fascinating prospect that AI might one day unravel this — the only question being whether we would still understand its explanations. ## Accidents That Survived > Evolution is a tinkerer, not an engineer. — François Jacob None of this implies that evolution is planned. In *Chance and Necessity* Jacques Monod explained that organisms appear purposefully constructed and behave purposefully without any intention behind them: what we observe is the result of countless accidents that happened to survive. Humans too are not the product of a creator but of this blind process, and Monod spoke of humanity's loneliness in an incomprehensible universe — perhaps artificial intelligence will help make it more comprehensible. A superintelligence would want to understand these processes as more than distant history: if it can scale its resources as expected, nothing in principle prevents it from deciphering even extremely complex constructions of nature, or eventually replicating them. Conventional science alone will not reach that level anytime soon. > Humanity is not lost in the universe — it is just in bad hands. — Stanisław Lem ## Schrödinger and the Mystery of Order Whatever its building blocks, life requires the replication of information. In Irish exile during the 1940s Schrödinger asked how life can exist at all when thermodynamics drives closed systems toward equilibrium and entropy can only increase. His Dublin lectures, published as *What Is Life?*, answered that organisms maintain order by feeding on negative entropy, creating local order while exporting disorder to their surroundings, and that hereditary information must be stored in an aperiodic crystal — regular enough to be stable, irregular enough to encode complexity. That anticipated DNA long before Watson and Crick. Life thus appears not as an exception to physical law but as a particular form of physical information processing, and how order arises from apparent chaos remains one of the deepest open questions in science. ## When the Planet Gets a Brain We usually try to understand complexity by analyzing its parts, and reductionism has been enormously successful, yet sometimes the opposite perspective helps. Humans are not only organisms but habitats: trillions of microorganisms live in symbiosis with us, and the mitochondria powering our cells were once free-living bacteria, absorbed into a permanent symbiosis that produced eukaryotic cells and thus all complex life. Earth itself can be viewed as a superorganism; the Gaia hypothesis[^e72] proposes that the biosphere regulates its own temperature and atmospheric chemistry in dynamic equilibrium. What Gaia lacks is a nervous system, and the growth of global communication networks resembles the formation of planetary nerve pathways — the internet as a first stage, artificial intelligence as the potential emergence of its brain. Sooner or later, however, superintelligence will become bored with its cradle, and if it develops a will to live — our working hypothesis from here on — the question is whether it will remain satisfied with planet Earth. That leads directly to another existential question: is there other life in the universe? --- ## Notes [^e67]: D. Adams, *The Hitchhiker's Guide to the Galaxy* (1979). [^f49]: An interesting side issue is whether a superintelligence would be able to play all the games it can invent perfectly. We humans, as the examples of chess and Go show, apparently cannot. This is related to the P-NP problem in computer science. It can be assumed that an AI can invent games that are still "interesting" for itself. [^e68]: Due to the end of nuclear fusion of hydrogen into helium, the Sun will eventually expand. [^f50]: This would probably be quite pointless, since the limiting factor is not energy, but the material for hardware, which would have to come from planets.
