AI is changing data science by adding generative and agentic tools to established predictive work—not by making forecasting, classification, or human judgment obsolete. The most useful trend to understand is this coexistence: teams are combining different kinds of AI while paying closer attention to reliability, data rights, cost, evaluation, and skills.
What “AI in data science” includes
AI in data science is broader than generative AI. The methods differ in what they do, and that difference matters when choosing a tool or evaluating its output.
- Predictive AI and classical machine learning use data to estimate an outcome, assign a category, or detect a pattern. Forecasting demand and classifying records are examples.
- Generative AI creates or transforms content such as text, code, or summaries. A data team might use it to summarize documentation, draft code, or help explore a dataset.
- Agentic systems use models to plan and carry out sequences of actions, often with access to tools or software. They can extend a workflow beyond producing a single answer, but each step creates another opportunity for error.
- Prescriptive methods help recommend an action given goals and constraints—for example, choosing a plan that balances competing objectives.
Gartner’s May 2026 summary of its Hype Cycle for Data Science and Machine Learning says forecasting and classification, rather than generative AI or agents, currently deliver most AI value. That is a reminder to match the method to the task instead of assuming the newest model is the best solution.
Which trends are changing data-science work?
Predictive models remain part of the toolkit
Generative AI has drawn attention, but data-science teams still need techniques suited to prediction, classification, and other structured tasks. Gartner’s 2026 summary describes leaders as needing to build and govern generative, agentic, predictive, and prescriptive models. In practice, those approaches can coexist in one organization—or one workflow—rather than replace one another.

Generative AI is widening the range of assisted tasks
In the UK Business Data Survey 2026, businesses using AI commonly reported using it for research and information gathering, and for summarizing or drafting. Data analysis and model building were also reported uses, but the survey found a substantial size difference: 32% of large UK businesses handling digitised data and using AI reported using it for data analysis or model building, compared with 6% of sole traders.
These examples do not mean an AI-generated analysis is automatically correct. Treat model output as work to verify, especially when it informs a decision or will be used downstream.
Agents are attracting interest, but interest is not proof of autonomy
The UK AI Labour Market Survey 2025, published in January 2026, found that 57% of respondents planned to adopt agentic AI within three years. This is reported intent, not observed adoption or a guarantee that the plans will happen.
Stanford HAI’s 2026 AI Index describes rapid gains on some agent benchmarks alongside continued failures on structured tasks and weaknesses on others. High scores on particular benchmarks do not establish that an agent can reliably complete an entire business workflow. For a real deployment, assess the exact sequence of tasks, permitted actions, and human checkpoints.

Stanford HAI reports that responsible-AI measurement and reporting are not keeping pace with capability measurement. It also notes trade-offs: improving one dimension, such as safety, can affect another, such as accuracy. A single overall score can hide these differences, so evaluate the qualities that matter for the specific use case.
The European Commission Joint Research Centre’s 2025 GenAI Outlook describes potential benefits in areas including science, health, education, and creative industries, alongside risks involving misinformation, bias, labour disruption, privacy, and over-reliance. It emphasizes multidisciplinary management and alignment with the EU legal framework; the report is broad policy context, not a product-level assessment.
How widespread is AI use?
Adoption figures are not interchangeable: surveys ask different questions and cover different populations. The UK government’s 2026 Business Data Survey explicitly notes that differing definitions, tasks, and roles make overall adoption difficult to measure consistently. Its figures below concern UK businesses handling digitised data in the 2025–2026 survey context, not all businesses worldwide.
| Measure | Reported result | Population and qualification |
|---|---|---|
| Use of AI-based technologies | 41% | UK businesses handling digitised data, reporting use in 2025–2026 |
| Use by business size | Large 82%; medium 58%; small 51%; micro 41%; sole traders 40% | UK businesses handling digitised data in the 2025–2026 survey |
| Use by selected sectors | Information and communication 62%; professional, scientific, and technical activities 54% | UK businesses handling digitised data in the 2025–2026 survey |
| AI integrated into existing business systems | 21% | Businesses using AI in the UK survey |
| Organizational AI adoption | 88% | Stanford HAI’s 2026 AI Index measure; different source and methodology from the UK survey |
The UK survey’s 41% and Stanford HAI’s 88% should not be read as conflicting estimates of the same thing. Their populations and measurement approaches differ. The UK result also suggests that reporting any AI use does not necessarily mean the technology has been deeply integrated into business systems.

What data-science teams should check before adopting a tool
Choose a tool for a defined task and operating context, not for a headline capability. Gartner’s July 2026 market commentary highlights value, cost, latency, performance, reliability, evaluation, cost transparency, and usage tracking as relevant considerations. Add the following checks to a pilot:
Rank #4
- Define the task and baseline. Record how the work is done now and what a useful improvement would mean. Use representative inputs and include edge cases.
- Measure output quality and failure modes. Check errors against an appropriate reference, document when the system fails, and test whether failures are detectable before they affect a decision.
- Measure operating burden. Track latency and cost alongside the time people spend reviewing, correcting, or re-running outputs. A fast answer may not save time if it creates substantial verification work.
- Check integration and oversight. Establish which systems the tool can access, what actions it may take, where approval is required, and how activity and usage are monitored.
- Review data handling before sharing data. Confirm what data may be sent, retained, or used for model training under the relevant contract and settings. The UK survey found that 73% of surveyed businesses handling digitised data were uncomfortable with their business data being used to train external AI models; this reports sentiment, not a legal rule.
- Reassess when the system or use changes. A new model version, different data, or expanded permissions can alter quality and risk. Keep evaluation and governance attached to the deployed use case.
Gartner’s July 2026 forecast estimates worldwide end-user spending on AI platforms for data science and machine learning at $19.405 billion in 2025 and $26.444 billion in 2026. It estimates total worldwide end-user spending on AI models and platforms at $39.311 billion in 2025 and $64.252 billion in 2026. These are forecasts, not final realized spending, and describe market direction rather than evidence that a particular platform is suitable for a team.

Model familiarity is only one part of readiness. The UK AI Labour Market Survey 2025, published in 2026, reports growing demand for data-science expertise and increasing complexity in AI skill requirements. In that survey, 66% of surveyed businesses employed data-science professionals, up from 48% in the previous study, and 35% of surveyed organisations said they struggled to fill AI roles. These figures describe the survey’s respondents, not every employer or labour market.
For practitioners, the useful skill mix includes:
- Core data science: statistics, machine learning, data preparation, and understanding how to select a method for a question.
- Evaluation: designing task-specific tests, identifying error patterns, and explaining what a benchmark does—and does not—show.
- Software and workflow skills: integrating tools into reproducible processes and knowing where human review belongs.
- Governance and communication: handling data rights, documenting limitations, and explaining uncertainty to decision-makers.
The World Bank’s 2025 Digital Progress and Trends Report: Strengthening AI Foundations identifies four foundations for inclusive and effective AI ecosystems: connectivity, compute, context (data), and competency (skills). Its framing is useful beyond model selection: a capable model cannot compensate for inaccessible infrastructure, unsuitable data, or a team without the skills to use and evaluate it.
What the evidence does—and does not—say
The available figures show active adoption, investment forecasts, and interest in new workflows, but they do not establish one universal adoption rate or prove that AI has displaced established data-science methods. Survey results are bounded by geography, population, and question wording; benchmark performance is bounded by the tasks tested; market figures are forecasts. Gartner’s Hype Cycle summary is an industry-research summary rather than a full methodology or vendor comparison, while the World Bank and JRC reports provide ecosystem and policy context rather than product rankings.
For a data-science team, the practical conclusion is to start with the problem: choose the method that fits it, test performance under real operating conditions, and account for data, infrastructure, people, and governance as part of the solution.
