Emerging technologies
Emerging technologies constitute novel advancements in science and engineering, marked by radical novelty, relatively fast growth, coherence in their applications, prominent potential impacts on society and economy, and inherent uncertainty regarding their full development and consequences.[1][2]
Key domains include artificial intelligence, synthetic biology, advanced materials, and neuroscience, which converge to enable breakthroughs in medicine, energy, and computing while reshaping labor markets and national security landscapes.[3][4]
As of 2025, salient examples encompass agentic AI for autonomous operations, post-quantum cryptography to counter quantum-enabled decryption threats, and spatial computing for enhanced virtual interactions, each accelerating productivity gains across sectors.[5][6]
Yet these innovations engender controversies over dual-use applications that facilitate both civilian progress and military escalation, alongside ethical challenges in biotechnology and AI deployment, such as algorithmic biases and loss of human agency, compounded by regulatory lags and disparities in technological access between nations.[3][7][8]
Definition and Characteristics
Core Definition and Scope
Emerging technologies refer to innovations characterized by radical novelty in application, relatively fast growth, coherence as a distinct system, prominent potential impact across sectors, and inherent uncertainty regarding their full development and societal effects.[9] This framework, derived from analyses of technological trajectories, distinguishes them from incremental advancements by emphasizing breakthrough potential rather than mere refinement of existing tools.[10] For instance, technologies like artificial intelligence and quantum computing exemplify this through their capacity to redefine computational paradigms, originating from foundational research but scaling rapidly via interdisciplinary integration.[11] The scope encompasses both entirely novel inventions and novel applications of established technologies that converge to enable transformative capabilities, often spanning domains such as biotechnology, materials science, and information systems.[12] Unlike mature technologies with predictable deployment, emerging ones involve high ambiguity in scalability, regulatory adaptation, and ethical implications, frequently emerging from scientific networks where qualitative synergies drive unforeseen qualitative shifts.[13] Their boundaries exclude routine engineering improvements, focusing instead on disruptors that breach established performance frontiers, such as neurotechnologies interfacing directly with biological systems or advanced robotics automating complex physical tasks.[14] This delineation underscores a process-oriented view: emergence arises cyclically from creative R&D ecosystems, with metrics like patent acceleration and venture investment signaling maturation stages.[15] While promising economic multipliers—evidenced by projections of trillions in global value addition by 2030 from converging tech stacks—such technologies demand scrutiny of risks, including cybersecurity vulnerabilities in nascent systems and uneven adoption driven by institutional lags.[16] Empirical tracking, via indicators like R&D expenditure growth exceeding 10% annually in key fields, aids in delineating scope without overgeneralizing to hype-driven narratives.[2]Distinguishing Traits and Metrics of Emergence
Emerging technologies are characterized by their disruptive potential, defined as the capacity to fundamentally alter existing markets, industries, or societal structures through superior performance or novel applications, often quantified by the extent to which they outperform incumbents by factors of 10x or more in key metrics like cost, speed, or efficiency. This trait stems from underlying exponential improvements in foundational components, such as computational power doubling roughly every 18-24 months per Moore's Law analogs in fields like AI, where model performance on benchmarks like ImageNet accuracy rose from 50% in 2011 to over 90% by 2020. Unlike incremental innovations, they exhibit path-breaking novelty, introducing mechanisms that bypass traditional constraints, as seen in CRISPR gene editing's enabling of precise DNA cuts at costs dropping from $1 million per genome in 2007 to under $1,000 by 2015, enabling applications previously deemed infeasible. A core distinguishing trait is rapid scalability coupled with high uncertainty, where technologies transition from laboratory prototypes to commercial viability within 5-10 years, but face risks like technical failure rates exceeding 90% in early-stage biotech ventures. This emergence is marked by network effects and ecosystem dependencies, amplifying adoption once critical mass is reached; for instance, blockchain's value proposition relies on decentralized consensus, with transaction throughput metrics improving from 7 transactions per second in Bitcoin (2009) to over 100,000 in newer protocols like Solana by 2023. Empirical studies identify S-curve adoption dynamics as a hallmark, starting with slow initial uptake due to high costs and limited infrastructure, followed by exponential growth, as evidenced by solar photovoltaic costs falling 89% from $0.36 per watt in 2010 to $0.04 per watt in 2020, driving global capacity from 40 GW to over 1 TW. Metrics for gauging emergence include exponential performance trajectories, tracked via logarithmic plots of capability versus time, where sustained slopes indicate ongoing emergence; quantum computing, for example, has shown qubit coherence times improving by orders of magnitude annually, from microseconds in 2010 to milliseconds by 2024. Investment velocity serves as a proxy, with venture capital inflows into AI surging from $4 billion in 2010 to $93 billion in 2021, signaling market anticipation of breakthroughs. Patent citation bursts provide another indicator, reflecting novelty and impact; mRNA vaccine technology saw citations spike post-2010, correlating with its deployment in COVID-19 vaccines achieving 95% efficacy in trials by late 2020. Regulatory lag metrics, such as time from proof-of-concept to approval, highlight emergence when shortened dramatically, as with FAA drone certification timelines compressing from years to months amid commercial pressures since 2016.| Metric | Description | Example Application |
|---|---|---|
| R&D Intensity | Ratio of R&D spending to revenue, often >15% in emerging fields versus <5% in mature ones | Semiconductors: 20-30% R&D intensity driving EUV lithography advances |
| Technology Readiness Level (TRL) | NASA scale from 1 (basic principles) to 9 (proven system); emergence peaks at TRL 4-6 | Fusion energy at TRL 3-4, with net energy gain achieved in 2022[17] |
| Market Penetration Rate | Annual growth >50% in early adopters | Electric vehicles: 2% global market share in 2018 to 14% in 2023 |
