Which Disruptive Technology Was Invented in the 2020s? Generative AI, mRNA Vaccines, and CRISPR Explained

ByAlex Morgan

Key takeaway: Which disruptive technology was invented in the 2020s? The strongest answer is generative AI: OpenAI’s GPT-3 arrived in 2020 and ChatGPT followed in November 2022, putting powerful content-creating AI in everyone’s hands. mRNA vaccines and the first approved CRISPR therapy are the decade’s other landmark breakthroughs, each reaching ordinary people for the first time in the 2020s.

A “disruptive technology” changes how an industry works, rather than just improving an existing product. That distinction matters here, because very few of the 2020s’ biggest technologies were invented from nothing in this decade. Most were built on decades of earlier research and then crossed a threshold — a working product, a first approval, mass adoption — between 2020 and today.

What “invented in the 2020s” actually means

Artificial intelligence dates back to the 1950s, the transformer architecture behind modern language models was published in 2017, mRNA research goes back decades, and CRISPR gene editing was described as a tool in 2012. So a strict “invented from scratch in the 2020s” test would leave almost nothing on the list. The fairer test — which technology became a real, widely used disruption during the 2020s — gives a clear winner, with two close runners-up. For a broader view of what counts as new, see our explainer on what modern technology means.

Which disruptive technology was invented in the 2020s? Generative AI leads

Generative AI creates new content — text, images, code, audio, and video — by learning patterns from large datasets, rather than only classifying or predicting. OpenAI’s GPT-3, described in a 2020 paper and offered through an API in June 2020, showed that one large language model could handle many tasks from a written prompt; it had 175 billion parameters, itself a headline at the time. The disruption arrived with the product: OpenAI released ChatGPT as a free research preview on November 30, 2022, built on a model from the GPT-3.5 series. Suddenly anyone could use a capable AI in a chat window, without code. Rival chatbots, image generators, and coding assistants followed within months, and AI features spread into search, office software, and phones. The internet and social media, by contrast, were already established long before this decade.

mRNA vaccines: a platform that proved itself in a pandemic

An mRNA vaccine carries temporary genetic instructions telling the body’s cells to make a harmless piece of a virus — in the COVID-19 vaccines, the spike protein — so the immune system learns to recognise it. No mRNA vaccine had ever been made available for mass use before 2020. That changed on December 11, 2020, when the U.S. Food and Drug Administration issued its first emergency use authorization for a COVID-19 vaccine, the Pfizer-BioNTech mRNA vaccine, for people aged 16 and older. It later became the first mRNA vaccine to receive full FDA approval, in August 2021, under the name Comirnaty. The disruption was speed and flexibility: once a target’s genetic sequence is known, an mRNA vaccine can be designed far faster than a traditional vaccine.

CRISPR therapy reaches patients for the first time

CRISPR-Cas9 is a gene-editing tool that cuts DNA at a precise location, letting scientists disable or correct a faulty gene. It won its discoverers the Nobel Prize in Chemistry in 2020, but for years it remained a laboratory tool. On December 8, 2023, the FDA approved Casgevy (exagamglogene autotemcel), a CRISPR-Cas9-edited cell therapy for sickle cell disease in patients aged 12 and older with recurrent vaso-occlusive crises — the first FDA-approved medicine to use CRISPR gene editing. The treatment edits a patient’s own blood stem cells so they produce more fetal haemoglobin, compensating for the faulty haemoglobin behind the disease. Going from lab tool to approved therapy in about a decade is unusually fast for medicine.

Agentic AI: the next wave already forming

Agentic AI describes systems that do not just answer a question but plan steps, use tools, check results, and complete multi-step work toward a goal. A key piece of plumbing arrived in November 2024, when Anthropic introduced the Model Context Protocol (MCP), an open standard connecting AI assistants to data sources and tools, since adopted by ChatGPT, Claude, Gemini, and Microsoft Copilot. The same shift — models becoming infrastructure other software is built on — is visible in our report on Mistral’s trillion-parameter open model.

How the 2020s contenders compare

Each contender disrupted a different field, so the fairest comparison is by milestone, impact, and who felt it first.

Technology 2020s milestone What it disrupted Who felt it first
Generative AI GPT-3 API, June 2020; ChatGPT, November 2022 Writing, coding, search, media production General public, workers, developers
mRNA vaccines First FDA emergency authorization, December 11, 2020 Vaccine speed and pandemic response Patients and health systems
CRISPR therapy First FDA approval, Casgevy, December 8, 2023 Treatment of genetic disease Sickle cell patients
Agentic AI Model Context Protocol, November 2024 How software gets work done Developers and businesses

What does it cost to use these technologies?

The cost of using these technologies ranges from free to more than $2 million, depending on which one you mean. Most major AI chatbots offer a free tier, with paid subscriptions for heavier use, while businesses pay per use through APIs. mRNA vaccines are normally paid for by health systems, not bought like software. CRISPR therapy sits at the other extreme: estimates put Casgevy and similar gene therapies at over $2 million per patient, reflecting a one-time, personalised treatment made from the patient’s own cells.

What you need before you use them

Before you use any of these technologies, you need far less than the inventors did — that is the point of a mass-market breakthrough. For generative AI, you need an account with a chatbot or an app with AI features built in, plus one habit worth building: checking important outputs, because models can be confidently wrong. For mRNA vaccines and CRISPR therapy, the prerequisite is medical: eligibility, a clinician’s assessment, and — for gene therapy — a specialist centre. For agentic AI tools, it is access to the software they connect to, and permission settings that limit what the agent may change.

Risks and limits to keep in mind

Generative AI can produce fluent but false information and reproduce biases in its training data, and it raises hard questions about copyright and jobs. mRNA vaccines, like all medicines, carry side effects and need cold-chain storage and manufacturing scale, and success against one virus does not guarantee the same result against every disease. CRISPR therapy is expensive, limited to eligible patients at specialist centres, and its long-term effects are still being followed. Agentic AI adds a new risk: an agent that can act, not just answer, can make mistakes at machine speed if its permissions are too broad.

Analysis: why generative AI is the answer, with a caveat

Analysis: If the question forces a single answer, it is generative AI — the only candidate both technically new at scale in the 2020s and adopted by the general public within the same decade, changing several industries at once. The caveat matters: calling it “invented in the 2020s” without qualification overstates the case, since its foundations are older. The honest version is that the 2020s invented mass-market generative AI, delivered the first mass mRNA vaccines, and approved the first CRISPR therapy. Watch next whether agentic AI gets its own ChatGPT moment, and whether mRNA and CRISPR platforms produce approved treatments beyond their first diseases.

Frequently asked questions

Which disruptive technology was invented in the 2020s?

Generative AI is the strongest answer. OpenAI’s GPT-3 was published and offered through an API in 2020, and ChatGPT launched as a free research preview on November 30, 2022, bringing large language models to the general public. mRNA vaccines and the first CRISPR therapy are the decade’s other landmark firsts, but generative AI changed the most industries the fastest.

Was artificial intelligence invented in the 2020s?

No, artificial intelligence dates back to the 1950s, and the transformer architecture behind modern language models was published in 2017. What the 2020s invented was mass-market generative AI: models large and capable enough, wrapped in products simple enough, for ordinary people to use every day.

What was the first mRNA vaccine?

The first mRNA vaccine made available for mass use was the Pfizer-BioNTech COVID-19 vaccine. The FDA issued its first emergency use authorization for it on December 11, 2020, for people aged 16 and older, and it later became the first mRNA vaccine to receive full FDA approval, in August 2021.

What was the first approved CRISPR therapy?

Casgevy (exagamglogene autotemcel) was the first FDA-approved CRISPR-based therapy. Approved on December 8, 2023, for sickle cell disease in patients aged 12 and older with recurrent vaso-occlusive crises, it edits a patient’s own blood stem cells to boost fetal haemoglobin.

What disruptive technology could come next in the 2020s?

Agentic AI is the leading candidate, because it moves AI from answering questions to completing multi-step tasks using tools and data. The Model Context Protocol, introduced by Anthropic in November 2024, gives AI assistants a standard way to connect to those tools, and it has since been adopted by most major AI providers.
