📊 Interpreting Compounding Growth

The chart above shows exponential adoption across three generations of models: GPT-4, GPT-4o, and GPT-5. Each model release brought new capabilities, but the growth curve remained unbroken — suggesting the value proposition continued to resonate even as expectations matured.

  • GPT-4 era (2023): Established ChatGPT as a serious productivity tool, not just a curiosity.
  • GPT-4o era (2024): Multimodal capabilities and faster performance expanded use cases into creative and technical domains.
  • GPT-5 era (2025): Advanced reasoning and embedded AI integrations moved ChatGPT from novelty to infrastructure — powering other apps, workflows, and platforms invisibly.
  • By October 2025, ChatGPT reached 800 million weekly active users — the fastest consumer adoption in tech history.

How Often Do You Really Use ChatGPT?

Survey Question: "How frequently do you use ChatGPT or another AI assistant in a typical week?"

18%15%35%32%
18% Never
15% Once per week
35% 2-3 times per week
32% Daily

🎯 Key Insights: Mass Adoption Accelerates

The data reveals a dramatic shift in AI adoption. Only 18% have never used AI tools, down significantly from 2023 surveys. Most striking: 82% of respondents have tried or actively use ChatGPT or AI assistants, with 67% using them at least once per week.

This represents a tipping point where AI has moved from early adopter territory into mainstream behavior. The combination of daily and frequent users (67% total) suggests AI is becoming embedded in regular workflows rather than remaining an occasional experiment.

  • 35% use AI 2-3 times per week — the largest segment, indicating regular, intentional usage.
  • 32% use it daily, treating AI as a core part of their workflow.
  • 15% are casual users (once per week), testing and exploring use cases.
  • Only 18% have never used AI — a minority that continues to shrink as tools improve and awareness grows.

Has AI Made You More Productive?

Survey Question: "Since using ChatGPT or similar generative-AI tools, how has your work productivity changed?"

Sample: 2,000 working-age adults in the U.S. and U.K. who use generative-AI tools at least once per week (October 2025)

💡 Key Insights: Clear Productivity Gains

The data shows a decisive productivity boost: 67% of weekly AI users report higher productivity, compared to just 9% who report lower productivity. This clear majority experiencing tangible benefits validates that AI is genuinely improving work output across a wide range of tasks.

Task-level analysis reveals where AI delivers the most value. Emails (29%) andresearch/summarising (26%) top the list — both cognitively demanding but highly repeatable tasks that AI handles well. Coding (15%) and learning (12%) lag behind, suggesting AI excels more at augmentation than at deep expertise work.

  • 67% report higher productivity — more than two-thirds experiencing tangible gains.
  • Only 9% report lower productivity, showing that the vast majority have learned to integrate AI effectively.
  • 24% see no change — likely users experimenting casually or in roles where AI hasn't yet fit their workflow.
  • Email and research tasks (55% combined) dominate productivity gains, validating AI's strength in information synthesis and communication.
  • The survey targeted weekly AI users, yet 91% report either gains or neutral impact — suggesting AI tools have reached a maturity level where most users can extract value.

How Worried Are You That AI Could Replace Your Job?

Survey Question: "How concerned are you that generative-AI tools (like ChatGPT or similar assistants) could replace your current job or role within the next five years?"

Sample: 2,000 working-age adults in the U.S. and U.K. who use generative-AI tools at least once per week (October 2025)

⚠️ Key Insights: Widespread Job Anxiety

Despite reporting productivity gains, 73% of AI users express at least moderate concern about job displacement within five years. This anxiety-adoption paradox reveals a critical tension: users recognize AI's benefits but fear they may ultimately work themselves out of a role.

The primary fear isn't outright job loss (21%) but role transformation (27%) — workers worry about losing autonomy, decision-making authority, and meaningful work even if they keep their title. Skills obsolescence (20%) and reduced career progression (18%) round out the top concerns.

  • 73% express moderate-to-high concern — showing anxiety spans nearly all skill levels and industries.
  • 36% are moderately concerned, the largest single group — suggesting cautious awareness rather than panic.
  • Only 27% report little-to-no concern, indicating job anxiety is widespread among AI users.
  • Role change (27%) tops outright job loss (21%) as the primary fear — workers are more concerned about diminished agency than unemployment.
  • The data aligns with Express Employment Professionals findings: 64% worry AI will limit job opportunities, and 47% fear their job could be eliminated entirely.
