- Conclusion: Is 2026 a Turning Point?
In April 2026, we stand at a historic inflection point in science and technology. Earth's temperature is threatening the Paris Agreement's 1.5-degree target, renewables are rapidly displacing fossil fuels, and SpaceX's Starship is opening a new era in space. This article comprehensively examines ten key areas at the frontier of science in 2026, from the latest climate data to the Artemis lunar program. Is the pace of the energy transition sufficient? Where is the future of space exploration headed? We assess the present and survey possible futures, grounded in data and evidence.
1. Climate Change Status -- 2025 Temperature Records and the 1.5-Degree Target
2025 Temperature Records
2025 was ranked as the third warmest year on record. Six major climate datasets confirmed this, while two placed it as the second warmest. According to Berkeley Earth's analysis, the global mean temperature in 2025 was approximately 1.44 degrees Celsius (plus or minus 0.09 degrees) above pre-industrial levels (1850-1900).
That was about 0.08 degrees cooler than 2024, which set the all-time record, and only 0.03 degrees cooler than 2023. In other words, global temperatures have hovered near the 1.5-degree threshold for three consecutive years. Scientists have described this as a warning shot from a shifting climate.
Why do these numbers matter? While a 0.01-degree difference may seem trivial, a 0.1-degree shift in the global average can amplify to several degrees in specific regions. The Arctic is warming at two to three times the global average rate, driving sea ice loss, permafrost thawing, and sea-level rise.
The 1.5-Degree Target in Crisis
The Paris Agreement's core goal of limiting warming to 1.5 degrees has effectively collapsed. The last three years have averaged above that threshold. When the Paris Accord was signed in 2015, projections suggested that the 1.5-degree mark would be reached sometime in the 2040s. Now warnings indicate it could be breached before 2030. Scientific American has described the situation as Earth still barreling toward the climate brink.
However, ocean cooling patterns in 2026 are expected to bring temperatures to roughly the fourth-highest on record, similar to 2025. The transition from El Nino to La Nina is temporarily suppressing temperature rise. But this does not change the structural warming trend.
Extreme Weather Becomes Routine
Rising temperatures translate directly into extreme weather events. Heatwaves, wildfires, floods, and droughts that once occurred on multi-decadal timescales now happen annually. Climate science calls this nonlinear amplification: when average temperature rises by one degree, the frequency and intensity of extreme events increase by more than that.
Compounding the challenge, the geopolitical energy crisis sparked by the Iran conflict has led some countries to delay coal plant retirements. Italy has pushed back its coal phaseout to 2038, Germany is reviewing reserve plant reactivation, and South Korea has extended three plants originally set to close this year. The tension between energy security and climate action has never been sharper.
2. Carbon Neutrality Roadmaps -- National NDCs and South Korea's Challenge
Major Country NDC Status
Countries continue to pursue nationally determined contributions (NDCs) under the Paris Agreement, but the collective ambition falls short of the 1.5-degree goal. According to the Climate Action Tracker, most nations have a gap between their stated targets and actual policy implementation.
U.S. policy reversals have reduced projected future renewable capacity by approximately 30 percent, delaying emissions reductions by roughly five years. This adds significant uncertainty to the global climate response. China, meanwhile, is transitioning rapidly, leveraging its dominance in solar panels, batteries, and electric vehicles to push into new markets. China occupies the paradoxical position of being both the world's largest carbon emitter and the largest investor in clean energy.
The EU is pursuing its Fit for 55 package, targeting a 55 percent reduction from 1990 levels by 2030. Its Carbon Border Adjustment Mechanism (CBAM) has begun imposing carbon costs on imports, directly affecting export-oriented economies like South Korea.
South Korea's 2050 Carbon Neutrality Roadmap
South Korea's Carbon Neutrality Act of 2021 made it one of the first IEA member countries to enshrine net-zero by 2050 into law. But the practical challenges are significant.
- 2030 NDC: 40 percent reduction below 2018 levels
- 2035 NDC: 30 percent renewable electricity target
- 2038 Basic Energy Plan: 70 percent carbon-free energy (including nuclear), with nuclear providing more than half
In August 2024, the Constitutional Court ruled parts of the Act unconstitutional and mandated that the government enact revised legislation by March 2026, including annual emission reduction targets for 2031-2049. This marked a significant instance of judicial pressure on climate policy. While similar climate litigation has occurred in Germany and the Netherlands, the Korean ruling was notable for demanding year-by-year targets.
South Korea faces unique challenges due to its industrial structure. Energy-intensive sectors -- steel, petrochemicals, semiconductors, and shipbuilding -- account for a large share of GDP. Decarbonizing these industries is technically difficult and must be balanced against international competitiveness.
U.S.-China Climate Technology Competition
Climate technology has become a core arena of geopolitical competition. China accounts for over 80 percent of global solar panel production and holds a dominant position in battery supply chains. In response, the United States is nurturing domestic clean energy manufacturing through the Inflation Reduction Act (IRA), while the EU is pursuing its Green Deal Industrial Plan to secure regional production capacity.
This competition has the positive effect of driving down renewable energy costs and accelerating innovation, but it also carries the risk that supply chain fragmentation and technology protectionism could delay the global energy transition. Since climate change is a problem that transcends borders, balancing competition with cooperation is essential.
3. Renewable Energy -- Solar, Wind, Batteries, and Green Hydrogen
Solar and Wind: Historic Buildout
Global renewable energy capacity saw its largest-ever increase in 2025. A total of 692 GW was added in a single year, representing 15.5 percent growth. Solar accounted for 510 GW, roughly three-quarters of all additions, while wind contributed 159 GW. Renewables now comprise nearly half of global power capacity.
In the United States, 86 GW of new generating capacity is planned for 2026, a record if realized. The breakdown: solar at 51 percent (43.4 GW), battery storage at 28 percent (24 GW), and wind at 14 percent (11.8 GW). A remarkable fact: over 99 percent of new U.S. generating capacity in 2026 will be solar, wind, or battery storage. New fossil fuel generation is effectively negligible.
In the UK, combined wind and solar output reached 11 TWh in March 2026, saving nearly one billion pounds in gas imports. This provides empirical evidence that renewables contribute to energy security.
Solar costs have fallen approximately 90 percent over the past decade, making it the cheapest source of electricity in many regions. Wind costs are also declining rapidly, particularly as offshore wind turbines grow larger and more efficient.
Battery Storage and Solid-State Batteries
Energy storage is the key technology for addressing renewable intermittency. When the sun sets or the wind stops, solar and wind power cannot generate electricity. Battery storage systems bridge this gap.
Planned utility-scale battery storage in the U.S. for 2026 stands at 24 GW, a 60 percent increase over the record 15 GW added in 2025. This rapid growth reflects both falling battery prices and growing demand for grid stabilization.
Solid-state battery technology also merits attention. Unlike conventional lithium-ion batteries that use liquid electrolytes, solid-state batteries use solid electrolytes, offering higher energy density and lower fire risk. They have potential applications in both EVs and grid storage. While mass production remains some years away, companies including Toyota, Samsung SDI, and SK On are targeting commercialization in the late 2020s. When commercialized, they could dramatically extend EV range and reduce charging times.
Green Hydrogen
Green hydrogen serves a complementary role to batteries for energy storage. Produced by electrolysis using surplus renewable electricity, it can be reconverted to power through fuel cells at approximately 50 percent efficiency. Despite the lower efficiency, green hydrogen is indispensable for several applications where batteries alone cannot substitute:
- Steel production: Direct reduction using hydrogen instead of coal (coking coal)
- Chemical industry: Decarbonization of ammonia and methanol production
- Long-distance transport: Heavy trucks, shipping, and aviation
- Seasonal energy storage: Using summer solar surplus in winter months
A recently developed solar battery material capable of storing sunlight and later converting it into hydrogen fuel has opened new pathways for long-duration renewable energy storage. While still at the experimental stage, the technology is innovative in integrating solar capture and hydrogen storage into a single material.
4. Nuclear Renaissance -- SMRs and Fusion
The Rise of Small Modular Reactors (SMRs)
Nuclear energy is being reevaluated as a reliable baseload power source independent of weather conditions. Small modular reactors (SMRs) have emerged as the centerpiece of next-generation nuclear. Unlike traditional large-scale nuclear plants (1,000+ MWe), SMRs are under 300 MWe and can be manufactured modularly in factories, then assembled on site.
Only China and Russia currently operate commercial SMRs. China's HTR-PM high-temperature gas-cooled reactor connected to the grid in 2021, and the 125 MWe Linglong One (ACP100) is targeting operational start by the end of 2026. France's EDF plans to complete the Nuward design by mid-2026, targeting a 400 MWe SMR for the 2030s market.
Multiple U.S. projects are also progressing:
- Last Energy's PWR-5 pilot reactor is under construction at Texas A&M, targeting criticality in 2026
- Radiant plans to test its first reactor at Idaho National Laboratory's DOME facility in 2026
- X-energy's Xe-100 project targets construction start in 2026 at Dow's Seadrift site in Texas, with operation by 2030
SMRs offer several advantages: shorter construction periods (3-5 years versus 10 years for large plants), lower upfront capital costs, and the ability to add modules incrementally as demand grows. They also feature passive safety systems that allow natural convection cooling in the event of power loss. However, per-MWe generation costs may be higher than large plants, and regulatory frameworks remain undeveloped in many countries.
Fusion Progress
Nuclear fusion has not yet reached commercial viability, but important milestones are being set. Fusion replicates the process by which the sun generates energy. If successful, it would provide a virtually limitless clean energy source.
In May 2025, Germany's Wendelstein 7-X, the world's largest stellarator, successfully generated high-energy helium-3 ions using radio waves for the first time. The stellarator approach differs from tokamaks by using external magnetic fields alone to confine plasma, theoretically enabling more stable operation.
Private fusion investment has also surged. Startups backed by investors including OpenAI's Sam Altman and SoftBank's venture capital arm, as well as companies like Commonwealth Fusion Systems and TAE Technologies, continue pushing toward commercial energy production. Experts project that the first commercial fusion power plants could become operational in the late 2030s to 2040s.
The greatest appeal of fusion lies in its nearly inexhaustible fuel supply. Deuterium can be extracted from seawater, and tritium can be produced from lithium. Unlike fission, fusion produces virtually no long-lived radioactive waste and carries no nuclear proliferation risk. While significant technical hurdles remain, success would represent the ultimate solution to the energy problem.
South Korea's KSTAR (Korea Superconducting Tokamak Advanced Research) also plays an important role in global fusion research. KSTAR has repeatedly set records for sustained high-temperature plasma confinement and contributes to the international ITER project.
5. The EV Market -- Global Sales and Charging Infrastructure
Explosive EV Sales Growth
The electric vehicle market continues its explosive expansion. Key figures:
| Year | Global Sales | Market Share |
|---|---|---|
| 2024 | 17.8 million | 19.9% |
| 2025 (projected) | 23.7 million | 25.5% |
| 2026 (projected) | - | approx. 27.5% |
| 2030 (projected) | - | 43.2% |
| 2040 (projected) | approx. 90 million | 83%+ |
China produces 71 percent of all EVs sold globally and accounts for approximately 60 percent of sales. Strong government support, domestic battery manufacturing leadership (CATL, BYD), and dense charging infrastructure underpin this position. BYD surpassed Tesla in 2024 global sales to become the world's largest EV maker.
The U.S. market is projected at approximately 2.25 million sales in 2025, maintaining a steady upward trajectory. Europe is accelerating its EV transition under tightening EU CO2 regulations, with a ban on new internal combustion engine vehicle sales set for 2035.
The South Korean market is also growing. Hyundai Motor Group is strengthening its global EV presence with the Ioniq series and EV6/EV9 models. The Korean government targets 4.5 million EVs on the road by 2030, supported by subsidies and charging infrastructure expansion.
Charging Infrastructure Challenges
The EV charging infrastructure market grew from approximately 40.2 billion dollars in 2025 and is projected to reach 238.8 billion dollars by 2033 (25 percent annual growth). The fast-charger segment captured 73.3 percent of market share in 2025. The Asia-Pacific region holds 68.2 percent of the overall market.
However, significant challenges remain. The United States has approximately 76,000 public station locations with 228,000 charging ports, but access is uneven, especially in rural areas. High installation costs, lack of dedicated charging spaces, and fluctuating power tariffs continue to impede deployment. Additional challenges include charging standard unification, payment system interoperability, and grid capacity assurance.
EVs and the Grid: A Bidirectional Relationship
One interesting development is V2G (Vehicle-to-Grid) technology. This concept uses EV batteries as distributed energy storage devices, feeding power back to the grid during peak demand. If millions of EVs are connected, they could function as a large-scale virtual power plant.
Second-life applications for EV batteries are also gaining attention. Batteries replaced in EVs still retain 70-80 percent of their original capacity and can be reused as stationary energy storage systems. This achieves the dual benefit of reducing the environmental burden of batteries and lowering renewable energy storage costs.
The convergence of autonomous driving technology and EVs is also accelerating. Autonomous electric taxis (robotaxis) have the potential to reduce the need for individual car ownership, improve transportation efficiency, and lower urban carbon emissions.
6. Space Exploration -- SpaceX Starship and Artemis
SpaceX Starship Status
SpaceX's Starship has reached operational status in 2026 after years of increasingly successful test flights. Standing approximately 120 meters tall with a 9-meter diameter, this massive rocket is fully reusable. SpaceX claims it can reduce launch costs by an order of magnitude compared to current rockets.
The key 2026 target is to place a Starship upper stage into Earth orbit and complete an in-space refueling test. Orbital refueling is a prerequisite for lunar and Mars missions. Starship's payload capacity (over 100 tons with orbital refueling) exceeds that of any other launch vehicle.
Starship simultaneously serves multiple roles:
- NASA lunar lander (HLS): Used for crewed lunar landings in the Artemis program
- Satellite launcher: Potential Falcon 9 successor for deploying satellites in bulk
- Mars transport: The backbone of SpaceX's long-term Mars colonization goal
- Point-to-point transport: A concept for ultra-fast intercontinental travel on Earth
Artemis Program Changes
The Artemis program underwent major restructuring in 2026. In late February 2026, NASA updated the program structure. Artemis III, originally a lunar landing mission, was redesigned as a demonstration mission. It will now conduct rendezvous and docking tests in low Earth orbit with one or both commercially developed lunar landers, SpaceX's Starship HLS and Blue Origin's Blue Moon, and test the new Axiom Extravehicular Mobility Unit (AxEMU) spacesuit.
The crewed lunar landing has been shifted to Artemis IV, now targeting early 2028. In March 2026, reports emerged that NASA was considering giving SpaceX an expanded role, including key lunar orbit tasks via Starship.
This schedule adjustment reflects the technical maturity challenges of Starship and the complexity of orbital refueling. A lunar landing requires multiple orbital refueling operations for Starship, and this capability has not yet been demonstrated.
7. Commercial Space -- Satellite Internet and the Space Economy
Starlink and Satellite Internet
SpaceX's Starlink operates approximately 9,400 satellites as of 2026, the largest satellite constellation in human history. Starlink provides high-speed internet worldwide, particularly in rural areas and developing countries lacking traditional communications infrastructure.
Beginning in 2026, about 4,400 of these satellites, currently at 550 km altitude, will be lowered to 480 km (298 miles). Lower orbits mean increased atmospheric drag, causing decommissioned satellites to re-enter the atmosphere faster and reducing space debris risk. This represents a proactive response by SpaceX to orbital congestion concerns.
However, mega-constellations have drawn criticism for interfering with astronomical observations. Ground-based telescopes repeatedly report satellite streaks crossing their image fields. The conflict between the astronomy community and satellite operators continues in 2026.
The Expanding Space Economy
The space industry is no longer limited to government-led exploration programs. Satellite internet, Earth observation, space tourism, and space manufacturing are all growing commercial sectors. According to Morgan Stanley projections, the global space economy could reach one trillion dollars by 2040.
In the geothermal energy sector, advanced drilling technologies derived from space applications are being deployed. Geothermal is attracting attention as a weather-independent, reliable renewable energy source with particular potential for serving data centers and large-scale energy demands. The geothermal industry is positioning itself for rapid expansion in 2026, establishing itself as one of the few renewable energy sources capable of providing baseload power.
The Asian Space Race
China's space program is advancing rapidly. China operates its own space station, Tiangong, and has achieved milestones including lunar far-side exploration (Chang'e 6 sample return success), and Mars exploration (Zhurong rover). India's ISRO is also pursuing its crewed spaceflight program (Gaganyaan) following the successful Chandrayaan-3 lunar landing.
Japan's JAXA is expanding its lunar and deep-space exploration capabilities, building on the success of its asteroid missions (Hayabusa2). South Korea, drawing on its experience operating the Danuri (KPLO) lunar orbiter, is targeting a lunar lander launch by 2032, while also focusing on achieving independent launch capability through the Nuri rocket's continued development.
8. Mars Exploration -- Sample Return and the Human Mission Roadmap
Mars Sample Return (MSR) Program
NASA's Mars Sample Return program aimed to bring back rock and sediment samples collected by the Perseverance rover. Perseverance has collected and sealed dozens of samples in Jezero Crater, including ancient lake sediments and volcanic rock that could harbor traces of past life, making them among the most important scientific samples in human history.
NASA was studying two landing architectures simultaneously to encourage competition and innovation, with a final design decision expected in the second half of 2026. However, in January 2026, the U.S. Congress confirmed that MSR would not receive funding, effectively canceling the program.
This was a major disappointment for the scientific community. The returned samples were expected to provide groundbreaking information on:
- Mars geological history and past environmental reconstruction
- Searching for ancient microbial fossils or traces of life
- Understanding Mars climate evolution
- Evaluating resources and conditions for future crewed exploration
Human Mars Exploration Outlook
Crewed Mars exploration remains far in the future. The one-way trip from Earth to Mars takes six to nine months, and a round-trip mission requires a minimum of two to three years. NASA's roadmap follows a stepwise approach: validate long-duration habitation and technologies on the Moon through Artemis, then proceed to Mars.
SpaceX has set more aggressive timelines, but critical challenges remain:
- Radiation shielding: Protecting astronauts from deep-space radiation
- Life support systems: Air, water, and food recycling in a closed environment over extended periods
- Long-duration microgravity effects: Bone density loss, muscle atrophy, and visual impairment
- Psychological factors: Managing the mental health of a small, isolated crew over extended periods
9. Space Debris -- Orbital Congestion and Mitigation Technologies
Growing Orbital Congestion
The rapid expansion of large satellite constellations has made low Earth orbit (LEO) congestion a pressing concern. Tens of thousands of trackable objects and hundreds of thousands of untrackable fragments currently orbit Earth. Even a 1-cm fragment traveling at 7-8 km per second can cause catastrophic damage to satellites or space stations.
In the first months of 2026, two Starlink fragmentation events occurred within three months. Satellite 35956 broke apart in mid-December 2025, and satellite 34343 suffered a debris event on March 29, 2026. These incidents have amplified concerns about orbital sustainability.
In the worst-case scenario known as Kessler Syndrome, orbital debris triggers a cascade of collisions that renders specific orbital altitudes unusable for decades. This would threaten the infrastructure of modern civilization, including satellite communications, GPS, and weather observation.
Mitigation Technologies
Several approaches are under development and deployment:
- Orbital lowering: Like Starlink's altitude reduction, placing satellites in lower orbits shortens natural decay timelines. At 480 km, satellites re-enter naturally within 5-10 years
- Active debris removal (ADR): Robotic arms, nets, and harpoons to capture defunct satellites. ESA's ClearSpace-1 and Japan's Astroscale are pursuing demonstration missions
- Collision avoidance systems: AI-powered systems that predict trajectories and execute automated evasion maneuvers. Starlink already operates autonomous collision avoidance
- International regulatory frameworks: Discussions continue on mandating orbital clearance within 25 years of end-of-life, with some advocating for a 5-year requirement
Space Sustainability and International Cooperation
The space debris problem cannot be solved by any single nation or company. Space is a global commons, and the degradation of the orbital environment affects all participants in space activities. Guidelines are being discussed primarily through the UN Committee on the Peaceful Uses of Outer Space (COPUOS), but their lack of legal binding force limits their effectiveness.
Key 2026 discussion topics include strengthened accountability for mega-constellation operators, the possibility of orbital usage fees, and international cost-sharing mechanisms for debris removal. Just as international norms for ocean environmental protection have developed over decades, norms for space environmental protection are expected to be gradually strengthened.
The space insurance market is also changing. As collision risk increases due to orbital congestion, satellite insurance premiums are rising. This is reflected in satellite operating costs, creating an economic incentive for operators to voluntarily strengthen safety measures.
10. Science Investment -- R&D Budgets and STEM Education
Scale of Energy Transition Investment
Global clean energy technology investment reached 1.8 trillion dollars in 2025, up 15 percent year-over-year. This demonstrates that climate technology has become a large-scale industry, not merely an environmental policy initiative. Private investment has surged particularly in solar, battery storage, and EV sectors.
Investment trends by sector:
- Solar manufacturing: China's dominant production capacity continues to expand, while the U.S. and India are focusing on building domestic production capabilities
- Battery technology: Investment in next-generation batteries (sodium-ion, solid-state) beyond lithium-ion is surging
- Nuclear energy: Venture investment in SMRs and fusion has reached all-time highs
- Green hydrogen: Government subsidies and private investment in electrolyzer manufacturing and hydrogen infrastructure are expanding
However, regional imbalances persist. China accounts for a large share of global clean energy investment, while U.S. policy reversals add uncertainty to the overall transition pace.
The Importance of STEM Education
Both the energy transition and space exploration require a highly skilled technical workforce. SMR design and construction, fusion research, battery materials science, and spacecraft engineering all demand cross-disciplinary expertise spanning physics, chemistry, materials engineering, and aerospace engineering.
Several fields face particularly acute workforce demand:
- Energy systems engineers: Integrated design of renewable energy and storage systems
- Nuclear engineers: Specialized personnel for SMR design, construction, and operation
- Data scientists: Grid optimization, weather forecasting, space debris tracking
- Materials scientists: Next-generation batteries, solar cells, hydrogen catalysts
- Aerospace engineers: Satellite design, launch vehicle development, space habitation systems
For countries like South Korea, developing STEM talent is foundational to achieving carbon neutrality targets and participating in the growing space economy. Specialized expertise in nuclear energy, batteries, and hydrogen will be decisive for the success of the energy transition. South Korea already possesses world-class capabilities in semiconductors, batteries, and shipbuilding, with substantial potential to extend these strengths into energy transition and space industries.
AI and Climate Technology at the Crossroads
Artificial intelligence is playing an increasingly important role in the energy transition and climate response. AI-powered grid optimization predicts renewable energy variability and automatically adjusts storage and distribution to enhance grid stability. AI is also being used to discover new battery materials and catalysts, accelerating research and development timelines.
However, the energy consumption of AI itself is surging. As large-scale data center power demand explodes, a paradoxical situation has emerged in some regions where data centers absorb the net increase in renewable energy. Managing the carbon footprint of the AI industry is one of the key challenges of 2026.
In the space sector, AI is widely used for satellite data analysis, space debris trajectory prediction, and autonomous spacecraft navigation. Systems are being built that use AI to analyze climate monitoring satellite data, enabling real-time surveillance of deforestation, glacier changes, and methane leaks.
Conclusion: Is 2026 a Turning Point?
Looking at the science and technology landscape of 2026, optimism and caution coexist.
Optimistic signals:
- Renewable energy capacity additions have established a trend that overwhelmingly outpaces fossil fuels. Over 99 percent of new U.S. generation in 2026 is clean energy
- SMR and fusion technologies are entering substantive development phases. Multiple SMRs may achieve criticality in 2026
- EV market share has surpassed one-quarter of global sales, with internal combustion engines projected to be overtaken in the 2030s
- Private space technology is advancing on both the exploration and infrastructure fronts. Starship could fundamentally change the economics of space access
Warning signals:
- The 1.5-degree target has effectively failed. The discussion may need to shift to a 2-degree ceiling
- Geopolitical crises are delaying decarbonization. The tension between energy security and climate action persists
- Critical science programs like Mars Sample Return have been shelved due to budget constraints
- Space debris problems are intensifying, with international governance failing to keep pace with technological advancement
Ultimately, the success of both climate action and space exploration depends less on technology itself and more on political will, international cooperation, and sustained investment. The technology is ready. The question is whether we can deploy it fast enough.
2026 may be remembered as a turning point or as a missed opportunity. The outcome depends on the choices we make from this point forward.
Individuals can contribute too. Energy-efficient lifestyles, choosing EVs or public transit, selecting renewable-based electricity plans, and pursuing STEM education and careers are all part of the transition. Staying informed about the frontiers of science and technology and making evidence-based choices -- that is the first step toward making 2026 a genuine turning point.
The twin grand challenges of climate change and space exploration ultimately converge on the same question: can humanity preserve its only planet while simultaneously preparing to expand into the cosmos? The science of 2026 suggests the answer is yes.
But turning that possibility into reality depends not on technology, but on our collective will and action.
