The first quarter of the 21st century is over! For people who lived in a time when the twenty-first century was "the future", this is a shocking realization. Things have not changed as much this time as they did in the first quarter of the 20th century, which saw the commoditization of the telephone, the invention of the airplane, and a global "war to end all wars" among other profound lifestyle changes.
But there are adults alive today for whom any year with a "19" as its first two digits is nothing but history. The recent 25 years are their experience, and the next 25 are what they, along with the rest of us, are now concerned with. There's no need to review the latest quarter century specifically, but we can use our experience to recognize a few changes that are going to continue into the next quarter century. Not in any particular order, but using numbering to count how many different things are going on.
- Artificial Intelligence: Large language models, task specific deep learning, and robotics.
- Big tech companies are spending hundreds of billions of dollars on the misguided notion that if Large Language Models like OpenAI's ChatGPT, Anthropic's Claude, Google's Gemini, and Microsoft's Copilot can carry on a conversation as intelligently as a bad politician who doesen't know or care if what he says to voters is true or accurate, they can become sane and superintelligent by simply giving them ten or 100 times more compute power.
- Task specific deep learning is likely to become pervasive. Machine learning systems are already transforming areas such as drug discovery, radiological diagnosis, and geological exploration for oil and geothermal resources.
- In work contexts, repetitive tasks are ideal for robotic automation, yet the ungainly locomation of bipedal humanoids is superfluous in most situations. Even the Jetsons' Rosie the Robot maid had wheels instead of feet. The current generation of robots lack a sense of touch, as robotics pioneer Rodney Brooks has bas oberved. Humans with similar limitations are called "disabled".
- The decimation of US government-sponsored research. For the past 75 years, the US government has pursued a strategy of sponsoring basic and applied research, which has made this country the global leader in innovation. This strategy has now been abandoned. Efforts by Trump and DOGE to destroy the government research-sponsoring establishment have been thwarted by the courts and by law-abiding bureaucrats following Congressional mandates, and have limited the reductions to single digit percentages in many areas. Nevertheless, the World Intellectual Property Organization now ranks the US last in its rankings of innovation growth. China was first, while The United States and Japan experienced the steepest drops, losing 9.7 and 7.2 percentage points respectively, followed by reductions in Germany, France, Italy, Canada, the Russian Federation, Brazil, and the United Kingdom. Since the 1950s, a talented and energetic young scientist had been able to expect to build a career on a continuous series of government grants -- no more: that promise has been permanently withdrawn.
- Climate change and its driver, fossil fuel energy.
- Farmers and countries with significant agricultural sectors that deny climate change wil experience avoidable declines in crop yields. Megadroughts of 1000 years ago that lasted 100 years may last indefinitely this time. Heat waves that kill tens of thousands of un-air conditioned people in Europe and South Asia will continue, while humid Persian Gulf locations will reach effective temperatures incompatible with human life.
- Photovoltaic electricity will continue to be the cheapest power the world has ever seen. It and wind power, both cheaper than fossil-fueled power, will overcome political obstacles as greed prevails over ideology, while in low income countries off-grid and microgrid photovoltaics will be deployed without waiting for government or big business to provide stable grid power.
- Healthcare decline. As global lifespans improve, they increase the number of people surviving to old age, when they will need assistance in daily activities. Yet those same countries with longer-lived citizens also experience declining birth rates, with fewer young people around to take care of them. This will create a gap in elder care availability until household robots become advanced enough to replace care providers. There will be a difficult social transition as workers displaced by AI language models and other automation discover that care worker jobs remain abundant. The US abandonment of evidence-based public health policies will hopefully be reversed in future administrations. Meanwhile, alliances of state public health departments have arisen to set their own policies independently of the federal government.
- Autonomous vehicles. In 2025 the ability of automobiles to safely operate on city streets without human drivers was incontrovertibly demonstrated. This milestone launches a technology transtion that may be as rapid as the 15-year demise of the human operated elevator, tempered by a replacement cycle for existing passenger automobiles that exceeds 14 years. People who drive their own cars will become as exceptional as people who ride their own horses. Logistics companies have been complaining of shortages of truck drivers for decades; autonomous trucks will solve that problem, to the dismay of teamsters' unions which have relied on shortages to support their demands for higher wages and better working conditions. Autonomous flying drones are transforming warfare in Ukraine and elsewhere, while self-piloting air taxis will at last fulfill the sci-fi dream of flying cars.
- Satellite megaconstellations will enable global wireless communications. Just as rooftop solar power enables less developed areas to leapfrog unreliable centralized power grids, satellite megaconstellations will enable those areas to leapfrog centralized voice and data networks. Remote areas can perform a double leapfrog, skipping over both wired and cellular infrastructures. But the price of never being out of touch will be never being out of sight of government and commercial surveillance.
- Honorable mention: the decline of the dollar as the global reserve currency. For more than 80 years, the US dollar has been the currency of choice for international transactions, due to the size and liquidity of its markets, and the stability that comes from a Federal Reserve bank that is independent of politically-driven fluctuations. President Trump is attacking that independence with all the means at his disposal, including criminal investigations of the Chair of its Board of Governors. Analysts are concerned that the value of the dollar relative to other currencies declined nearly 10% in 2025, although they fail to incorporate a perspective that it's up nearly 20% in the past 20 years. Yet gold and other precious metals, traditionally a haven in times of trouble, have doubled or more in their dollar prices in 2025. If the stability of the dollar can no longer be trusted, candidates for an alternative reserve currency include the Euro, the Chines Renminbi, and the basket of currencies that form the World Bank's Special Drawing Rights. None of these seem significantly more attractive at this time; a multipolar situation where they each are used for different purposes seems likely. That would allow politicians to claim dominance over "what's important" regardless of global totals.
Because socioeconomic systems include creative human actors who can choose "none of the above" for their decisions, their future is fundamentally unpredictable. Mathematical chaos theory identifies the rate of growth of unpredictability with a "Lyapounov exponent" that specifies how rapidly fluctuations diverge from their past trajectories, but economic theories incorporating this phenomenon cannot be found. Journalists and other pundits can make short term predictions, but how long anyone can expect those predictions to stay valid remains a mystery.
Unpredictability arising bottom-up from amplified micro-fluctuations in intrinsically chaotic systems is complemented by top-down shocks in hierarchically organized systems, where the impacts of dictatorial leaders or unplannable technological breakthroughs such as usable room temperature superconductors, cannot be timed or scoped. We must simply be aware of the possibilties, and be prepared to adapt to them if they chance to arrive.
