Three major scientific and technological revolutions are currently underway with enormous potential: digital transformation (multi-decade, accelerating), biomedical and life sciences revolution, and energy transition technology—and these technologies are not only delivering breakthroughs but are becoming widely accessible and cost-declining.

There are two dimensions to AI policy: (1) preventing downside risks from inappropriate AI use (intellectual property, bias, misuse), and (2) accelerating positive adoption across sectors by providing support to small and medium-sized businesses that lack the resources of large firms like JP Morgan.

Adverse selection is a market failure where inability to distinguish between different product qualities causes high-quality products and participants to exit the market because the equilibrium price reflects average quality; this can cascade and destroy entire markets.

Climate change represents an existential challenge where the carbon budget for limiting warming to 1.5°C will be exhausted before the end of this decade at current trajectories, making overshoot of climate targets nearly inevitable unless global course changes rapidly.

Calculated risk-taking should be done serially, not in parallel: if pursuing a risky career move (entrepreneurship, academic research), don't simultaneously take on other major risks (large mortgage, starting a family during transition) because this limits your ability to execute any of them well and reduces odds of success.

Generative AI is likely to have its dominant impact through human-machine collaboration and augmentation rather than pure automation of jobs; the question is how to define the task—if you define it narrowly (write first draft of report) it looks like automation, but if you define it properly (produce the needed report), it's augmentation of human capability.

The Internet and digital access have transformed the informational structure of markets by making large amounts of information available at negligible cost, which democratizes information and reduces asymmetries; however, this raises new questions about what information is credible and trustworthy.

Central banks failed to recognize non-transitory supply-side constraints and bet instead that inflation would be transitory, leading them to start interest rate increases late, which then had to be done faster and more aggressively than might otherwise have been necessary.

The U.S. government has engaged in a fiscal-monetary policy mismatch: the Federal Reserve is raising rates and doing quantitative tightening to fight inflation, while the administration and Congress are running historically high government spending as a percentage of GDP (outside wartime), putting stimulus and brakes on the economy simultaneously.

The American economy has proven 'stunningly resilient' because: (1) fundamental dynamism remains in place, and (2) the pandemic-era government transfer of balance sheet damage from households and corporations to the sovereign balance sheet left critical sectors with stronger balance sheets compared to the Great Financial Crisis, enabling continued consumption and reducing near-term default risk.

Pandemic fiscal stimulus had dual consequences: it prevented balance sheet collapse and supported consumption (positive), but it also increased velocity of money and drove inflation (negative consequence that was underestimated).

Private equity valuations are adjusting more slowly than public equity valuations to the new interest rate regime, making the transition to lower valuations 'not a fun process' for PE investors and portfolio companies.

Solar energy costs have fallen to between one-fifth and one-tenth of their cost 10 years ago, and in suitable environments, solar is now cost-competitive with traditional fossil fuel-based electricity generation.

AlphaFold (DeepMind/Alphabet) solved the protein structure prediction problem by taking the amino acid sequence of proteins and predicting their three-dimensional structure with near-perfect accuracy, then released predictions for 200 million known proteins as open-source public goods—representing a seismic productivity advance for biomedical science.

Information asymmetries between buyers and sellers are far more prevalent than typically taught in introductory microeconomics, and they cause markets to function poorly when gaps are large; reducing these asymmetries through signaling, disclosure, and transparency is crucial for market function.

Signaling—actions or credentials that are costly to obtain and negatively correlated with underlying quality characteristics that buyers want to know—helps close information gaps; examples include graduating from prestigious institutions (MIT, Stanford), executive dividend cuts, and management stock purchases.

Young people have a disproportionate advantage in creating and implementing breakthrough ideas because they are not yet 'trapped by conventional wisdom' and have less accumulated cognitive baggage, though there are also advantages to age and experience.

The financial impact of higher education is a combination of two effects: actual human capital acquisition (skills, knowledge) and signaling (screening, credentials); Spence's work focused on the signaling component without denying that human capital acquisition also occurs.

Loss of trust in institutions has been a major consequence of distributional failures in globalization; because governance and policy changes require collective action and buy-in, widespread loss of trust makes it harder to implement solutions even when they're rationally beneficial to most people.

The economics profession has shifted in the past 10-15 years toward much more serious attention to distributional issues and inequality, moving away from the prior position that globalization's aggregate benefits justified losses for some groups (because losers could theoretically be compensated, even though in practice they weren't).
