Introduction: Triumphs and tragedies (Feb 16)
Who has had the greatest positive impact on the world? Which inventions and ideas were critical? Conversely, which ideas and inventions were most harmful? We’ll generate a list of great problems and discuss what we may be missing.
Great Problem: Mental Health (Feb 18) with Professor Rosalind Picard, MIT
An estimated 20% of people suffer from mental illness at any given time. Many more are miserable. How many of these problems are biological, and how many environmental? Do people care more about subjective happiness or fulfillment? What are the most effective treatments today? What could we invent to improve mental well-being?

Technological trajectories (Feb 23)

Great Problem: Global Health and Development (Feb 25) with Dr. Neil Buddy Shah, GiveWell
Development improves health, improving health fosters economic development, and at least one of them seems to improve well-being. Which solutions were the most effective historically, and what are the outstanding problems today? How can we measure what we care about? What are the side-effects of metrics? What do we lose by relying on them?

Great Problem: Energy (Mar 11) with Professor Anne White, MIT
Advances in computation, which are unquestionably the most transformative of the last fifty years, are noteworthy for requiring minimal energy. “Reduce, reuse, recycle” is an oft-heard mantra. But if we had access to unlimited clean energy, almost every material problem could, in principle, be solved.

Incentives and Biases (Mar 16)
The actions of rational agents are constrained by incentives, and people aren’t purely rational due to the cognitive heuristics evolved in the ancestral environment. Understanding the constraints imposed by evolutionary game theory and cognitive biases may be important for addressing Great Problems.

Project Brainstorming (Mar 25)
Discuss ideas and assemble into groups for the first project.
What about nonhumans? (Mar 30)
People value human lives and human suffering more than the lives and suffering of animals. The proffered reasons run the gamut from consciousness and theory of mind to straightforward speciesism. Still, even if the moral worth of animals is less than that of humans, few would argue that they have zero worth; the arc of moral concern has moved from bear-baitings and burning cats to laws against animal cruelty. Even given reduced moral worth on an individual level, there are many more animals than humans – and someday, software may become worthy of moral concern. To those who accept these premises, nonhuman well-being may be the most important neglected challenge of our time.
Due:
- “The life cycle of software objects” Links to an external site., in Stories of Your Life and Others (T. Chiang)
Great Problem: Animal Well-Being (Apr 1) with Kai Steinmetz, New Harvest
The animal well-being movement has focused on factory farming, which consumes more than sixty billion birds each year. Corporate campaigns pressuring producers to improve conditions have been increasingly successful. Meat substitutes and cultured meat appear quite promising, but only for a fraction of animal products. There are further complications: what about fish, more of which are farmed each year than chickens, and still more caught wild?
Due:

All groups will present their projects on potential solutions or a new cause for discussion.
Due:
- Mid-term group projects
Great Problem: Climate and Geoengineering (Apr 8) with Professor David Keith, Harvard
Most now agree that anthropogenic climate change is a major problem, with most realists assuming that warming of 2oC is unavoidable. That degree of warming will substantially worsen water and food shortages and gradually submerge land occupied by a nontrivial fraction of humanity. The tail-end feedback risks may be much worse. What can we do? What should we do?
Due:
- Evaluating climate geoengineering proposals in the context of the Paris Climate Agreement temperature goals Links to an external site. (Lawrence et al)

- The overwhelming importance of the far future Links to an external site. (N. Beckstead)
Great Problem: Physical Catastrophe (Apr 15) with Professor Toby Ord, Oxford
Volcanoes and asteroid impacts are thought to have been responsible for all historical mass extinction events. The reduction of the human population to just ten thousand people and the fall of Rome as well as many other ancient civilizations are thought to have resulted from climatic shifts. More recently, humanity has built devices capable of comparable devastation: in 1983, a billion people nearly died from an all-out nuclear exchange.

Great Problem: Civilizational Resilience (Apr 22) with Dr. Danny Hillis, Applied Invention
There appears to be an inherent tradeoff between efficiency and robustness. By definition, a maximally efficient system has no redundancy. Just-in-time manufacturing minimizes warehouse storage time and wasted materials, but is maximally fragile to supply chain disruptions. How can we enhance resilience against market forces? In the worst-case scenario of a total civilizational collapse, can we help our successors rebuild? Better?
Due:
- The Precipice Links to an external site. Chapter 7 (T. Ord)
- "The fragility of interdependency" Links to an external site. (A. Vespignani)

Potential Game Changer: Reweaving Perception (Apr 27)
The world we experience is not the world we live in. Everything we know is mediated through our senses… which can be modulated or replaced. What will happen when fiction and the virtual are so good that we cannot distinguish them from reality?

Project Brainstorming (Apr 29)
Discuss ideas and assemble into groups for final projects
Potential Game Changer: Shaping Future Humans (May 4)
People have always tried to control who their children will become. The goal may be a child who is bolder or meeker, kinder or harsher, more obedient or more creative, but they have largely failed. The genes that play a major role in shaping our behavioral patterns and capabilities were themselves shaped by evolution in the ancestral environment. For the first time, technology could change them.
Due:

- Watch GATTACA
Great Problem: Exponential biology (May 6) with Professor Megan Palmer, Stanford
The greatest catastrophes in human history were all pandemics. In 13th-century Europe, the Black Death killed one out of every two people. It recurred so frequently that Britain’s population did not recover until the 17th century. Relatively speaking, COVID-19 is comparatively mild, but it has turned virtually every global development indicator negative. Security researchers note that any system vulnerable to happenstance is helpless in the face of deliberate attack. Given COVID-19 and the fact that an increasing number of people can make viruses from synthetic DNA, what happens when we learn to make – and weaponize – pandemics?
Due:
- “Inoculating science against potential pandemics and information hazards” Links to an external site. (K. Esvelt)
- “The Unilateralist's Curse” Links to an external site. (N. Bostrom et al)
Recommended:
- The Fall of Rome: And the End of Civilization Links to an external site. (B. Ward-Perkins)
Potential game-changer: Extended intelligence (May 11)
The working memory of the human brain is quite constrained, imposing a major limitation on cognitive processing. Our sensory inputs are optimized for visual and auditory acuity, which are not optimized for bandwidth when searching for and retrieving information or identifying patterns. Methods of overcoming these problems to create more effective “computational exoselves” may substantially change the basal capabilities of people who already exist.
Due:
- “Physical principles for scalable neural recording” Links to an external site. (Marblestone et al)
Recommended reading:
- This Alien Shore Links to an external site. (C.S. Friedman)
Great Problem: Artificial General Intelligence (May 13)
Chimpanzees are nearly extinct and mostly reside in zoos. What happens when we create agents more capable than we are? Even given perfect alignment with human interests, machines with significantly superhuman competence will upend the strategic gameboard, creating potentially dangerous incentives for great powers.
Due:
- “Of Myths and Moonshine” (S. Russell)
Recommended reading:
Human compatible: Artificial intelligence and the problem of control Links to an external site. (S. Russell)
Project Presentations (May 18)

Project Presentations (May 20)
