# AI Usage Patterns & Adoption Research
**Last updated:** March 22, 2026  
**Compiled from:** Primary surveys and reports published 2024–2026

## Data Quality Notes

Before the data: a note on source reliability.

- **Gallup** (n=20,000–23,000 U.S. workers, quarterly): Gold standard for U.S. workplace adoption. Probability-based panel, large sample, reported confidence intervals. Treat these figures as the most reliable floor.
- **Pew Research**: Nationally representative, rigorous methodology. Strong for general adult sentiment and usage patterns in the U.S.
- **McKinsey Global Survey on AI**: Self-selected online panel of executives. Respondents are disproportionately from large, tech-forward organizations. Numbers skew high.
- **EY Work Reimagined Survey** (n=15,000 employees + 1,500 employers, 29 countries): Large sample, good global coverage, but online self-selected.
- **Microsoft Work Trend Index** (n=31,000, 31 countries): Knowledge workers only, excludes frontline. Skews toward office/desk workers.
- **Wharton/GBK AI Adoption Report** (n=~800 enterprise decision-makers per wave): Enterprise leaders only, U.S.-based, >1,000 employees and >$50M revenue. Not representative of small business or general workforce.
- **Slack/Salesforce surveys**: Conducted by or for AI-interested companies. Strong selection bias toward desk workers already using these platforms. Treat as upper bounds.
- **SSRS/Edison Research AI User Metrics** (Feb 2026): New panel measuring U.S. consumer AI chat usage. Methodology unclear at launch.
- **Stack Overflow Developer Survey** (~65,000 respondents): Self-selected, skews toward already-engaged developers. Coverage of casual/reluctant devs is limited.
- **JetBrains Developer Ecosystem** (n=24,534, balanced by geography/employment): Better methodology than Stack Overflow for developer stats.
- **Menlo Ventures** (n=~500 enterprise decision-makers; n=5,000 U.S. adults for consumer): Small enterprise sample, VC-run survey so framing is bullish. Useful for market-sizing and tool share.
- **Exploding Topics / aggregator sites**: Secondary compilations. Only cited here when they trace back to verifiable primary sources.

## 1. Overall Adoption Rates

### 1a. U.S. General Adult Population

| Metric | Rate | Source | Date |
|--------|------|---------|------|
| Used AI in the past 6 months | 61% | [Menlo Ventures, State of Consumer AI](https://menlovc.com/perspective/2025-the-state-of-consumer-ai/) | Jun 2025 |

| Not using AI at all (non-adopters) | 39% | [Menlo Ventures, State of Consumer AI](https://menlovc.com/perspective/2025-the-state-of-consumer-ai/) | Jun 2025 |

**Weekly AI chat platform market share (U.S. adults, Feb 2026):**
- ChatGPT: 36%
- Google Gemini: 26%
- Microsoft Copilot: 14%

Source: [SSRS/Edison AI User Metrics](https://ssrs.com/news/half-of-americans-using-ai-chat-on-weekly-basis/)

**Pew note on perception vs. intentional use:** The 62% "interact with AI several times a week" figure includes passive interactions (e.g., AI recommendations in apps). Intentional ChatGPT-style use is lower. Menlo's 61% "used AI in the past 6 months" and SSRS's 52% weekly are better proxies for active, intentional usage.

### 1b. U.S. Workforce

| Metric | Rate | Source | Date |
|--------|------|---------|------|
| Use AI at work at least a few times a year | 46% | [Gallup Q4 2025](https://www.gallup.com/workplace/701195/frequent-workplace-continued-rise.aspx) | Jan 2026 |
| Use AI at work frequently (several times a week+) | 26% | [Gallup Q4 2025](https://www.gallup.com/workplace/701195/frequent-workplace-continued-rise.aspx) | Jan 2026 |
| Use AI at work daily | 12% | [Gallup Q4 2025](https://www.gallup.com/workplace/701195/frequent-workplace-continued-rise.aspx) | Jan 2026 |
| Never use AI in their role | 49% | [Gallup Q4 2025](https://www.gallup.com/workplace/701195/frequent-workplace-continued-rise.aspx) | Jan 2026 |
| Use AI "at least some" in their work | 21% | [Pew Research (Sep 2025 survey)](https://www.pewresearch.org/short-reads/2026/03/12/key-findings-about-how-americans-view-artificial-intelligence/) | Mar 2026 |
| Don't use AI much or at all in their job | 65% | [Pew Research (Sep 2025 survey)](https://www.pewresearch.org/short-reads/2026/03/12/key-findings-about-how-americans-view-artificial-intelligence/) | Mar 2026 |

**Trend (Gallup, U.S. employed adults):**

| Quarter | Total use (few times/year+) | Frequent (few times/week+) | Daily |
|---------|----------------------------|---------------------------|-------|
| Q2 2023 | ~25% | ~13% | ~5% |
| Q2 2024 | ~33% | ~15% | ~8% |
| Q2 2025 | 40% | 19% | 8% |
| Q3 2025 | 45% | 23% | 10% |
| Q4 2025 | 46% | 26% | 12% |

Source: [Gallup Q4 2025](https://www.gallup.com/workplace/701195/frequent-workplace-continued-rise.aspx), [Gallup Q3 2025](https://www.gallup.com/workplace/699689/ai-use-at-work-rises.aspx)

**Important Gallup caveat:** Gallup surveys all employed U.S. adults, including frontline retail and manufacturing workers. This is the most conservative (and arguably most accurate) picture of the full workforce. Knowledge-worker–only surveys produce far higher numbers.

**Gap between surveys:** Pew's September 2025 survey found only 21% of workers use AI at least somewhat — compared to Gallup's 45% who use it "a few times a year or more." The difference likely reflects question framing: Pew asked about work being "done with AI," while Gallup includes any usage.

### 1c. Knowledge Workers Specifically

| Metric | Rate | Source | Date |
|--------|------|---------|------|
| Global knowledge workers using AI tools regularly | 75% | [Microsoft Work Trend Index 2024](https://www.worklytics.co/resources/2025-ai-adoption-benchmarks-employee-usage-statistics) | 2024 |
| Desk workers using AI at least occasionally | 60% | [Slack New AI Advantage survey](https://slack.com/blog/news/the-new-ai-advantage) | ~Apr 2025 |
| Desk workers using AI regularly (at least weekly) | 42% | [Slack New AI Advantage survey](https://slack.com/blog/news/the-new-ai-advantage) | ~Apr 2025 |
| Daily AI use among desk workers | ~20% (1 in 5) | [Slack New AI Advantage survey](https://slack.com/blog/news/the-new-ai-advantage) | ~Apr 2025 |
| White-collar workers who frequently use AI daily | 27% | [aristeksystems.com (citing unspecified 2025 survey)](https://aristeksystems.com/blog/whats-going-on-with-ai/) | 2025 |
| Enterprise leaders using Gen AI at least weekly | 82% | [Wharton/GBK AI Adoption Report 2025](https://knowledge.wharton.upenn.edu/special-report/2025-ai-adoption-report/) | Oct 2025 |
| Enterprise leaders using Gen AI daily | 46% | [Wharton/GBK AI Adoption Report 2025](https://knowledge.wharton.upenn.edu/special-report/2025-ai-adoption-report/) | Oct 2025 |

**Slack/Microsoft survey note:** These surveys sample desk workers — people already using platforms like Slack, Teams, and Outlook. They exclude frontline, manufacturing, and service workers. Treat these as upper-bound estimates for knowledge worker adoption, not the broader workforce.

---

### 1d. Enterprise Organizations

| Metric | Rate | Source | Date |
|--------|------|---------|------|
| Organizations using AI in at least one business function | 88% | [McKinsey State of AI 2025](https://www.mckinsey.com/capabilities/quantumblack/our-insights/the-state-of-ai) | Nov 2025 |
| Organizations using AI in at least one business function (prior year) | 78% | [McKinsey State of AI 2025 (citing 2024 data)](https://www.mckinsey.com/~/media/mckinsey/business%20functions/quantumblack/our%20insights/the%20state%20of%20ai/2025/the-state-of-ai-how-organizations-are-rewiring-to-capture-value_final.pdf) | 2025 |
| Organizations using AI in at least one function (2023) | 55% | [McKinsey State of AI 2025 (citing 2023 data)](https://www.mckinsey.com/~/media/mckinsey/business%20functions/quantumblack/our%20insights/the%20state%20of%20ai/2025/the-state-of-ai-how-organizations-are-rewiring-to-capture-value_final.pdf) | 2025 |
| Organizations actively scaling AI (not just piloting) | ~33% | [McKinsey State of AI 2025](https://www.mckinsey.com/capabilities/quantumblack/our-insights/the-state-of-ai) | Nov 2025 |
| Companies with >$5B revenue that have reached scaling phase | ~50% | [McKinsey State of AI 2025](https://www.mckinsey.com/capabilities/quantumblack/our-insights/the-state-of-ai) | Nov 2025 |
| EU enterprises (10+ employees) using AI technologies | 20% | [Eurostat 2025, via Omniflow](https://www.omniflow.team/blog/ai-workplace-statistics) | 2025 |
| Organizations that have integrated AI (per their employees) | 38% | [Gallup Q4 2025](https://www.gallup.com/workplace/701195/frequent-workplace-continued-rise.aspx) | Jan 2026 |

**McKinsey note:** McKinsey's respondents skew toward executives at large, global companies. The 88% figure likely reflects aspiration and any form of AI use (including embedded AI in existing tools), not transformative deployment.

**Organizational AI adoption trend (McKinsey):**
- 2023: 55%
- Early 2024: 72%
- Late 2024: 78%
- 2025: 88%

---

## 2. User Segmentation

### 2a. Non-Users / Skeptics

**Scale:** Approximately 39% of U.S. adults are non-adopters (Menlo Ventures, Jun 2025). Gallup finds 49% of all U.S. employed adults never use AI in their role (Q4 2025).

**Who they are:**
- Older adults: 54% of those 65+ interact with AI less than several times a week ([Pew, Sep 2025](https://www.pewresearch.org/science/2025/09/17/ai-in-americans-lives-awareness-experiences-and-attitudes/))
- Lower-educated: Only 20% of adults with a high school diploma or less interact with AI several times a day, vs. 46% of postgrads ([Pew, Sep 2025](https://www.pewresearch.org/science/2025/09/17/ai-in-americans-lives-awareness-experiences-and-attitudes/))
- Lower-income: 53% of households under $50K use AI, vs. 74% of households over $100K ([Menlo Ventures, State of Consumer AI](https://menlovc.com/perspective/2025-the-state-of-consumer-ai/))
- Frontline and non-remote workers: Only 32% total AI use vs. 66% for remote-capable workers ([Gallup Q4 2025](https://www.gallup.com/workplace/701195/frequent-workplace-continued-rise.aspx))

**Why they don't use AI (Menlo Ventures non-adopter survey):**
- Don't see a need for AI in daily life: 63%
- Prefer interacting with people over machines: 80%
- Worry about data privacy and security: 71%
- Don't trust the information AI provides: 58%
- Don't know how to use AI tools effectively: 48%
- Believe AI tools are biased: 40%
- Need to feel accountable to another human: 53%
- Lack access: 27%

**McKinsey employee archetypes (Jan 2025 workplace report):**
McKinsey identified four employee sentiment archetypes around gen AI:

| Archetype | % of Employees | Comfortable Using Gen AI | Believe in Net Benefits (5 yrs) |
|-----------|----------------|--------------------------|----------------------------------|
| Doomers (strongly opposed) | 4% | 47% | 54% |
| Gloomers (skeptical) | 37% | 79% | 82% |
| Bloomers (optimistic) | 39% | Higher than Gloomers | Higher than Gloomers |
| Zoomers (enthusiastic adopters) | 20% | 91% | 87% |

---

### 2b. Dabblers (Tried It, Infrequent Use)

No survey has cleanly isolated "dabblers" as a segment, but triangulating from available data:

- Gallup's data implies approximately 20% of U.S. workers use AI occasionally (a few times a year) but not frequently — the gap between total users (46%) and frequent users (26%).
- Menlo Ventures places 61% of U.S. adults as having used AI in the past 6 months, with ~39% non-adopters and ~20% daily users, implying a large middle band (~40% of all adults) who have tried AI but don't use it daily.

**What dabblers use AI for (Gallup Q2 2025):**
Among all workers who use AI at least yearly, the top reported uses were:
- Consolidating or summarizing information: 42%
- Generating ideas: 41%
- Learning new things: 36%

Source: [Gallup Q3 2025 report](https://www.gallup.com/workplace/699689/ai-use-at-work-rises.aspx)

---

### 2c. Mainstream Users (Weekly Use)

- **52% of Americans** use AI platforms at least weekly as of February 2026 ([SSRS/Edison](https://ssrs.com/news/half-of-americans-using-ai-chat-on-weekly-basis/))
- **42% of desk workers** use AI regularly (at least weekly) ([Slack survey](https://slack.com/blog/news/the-new-ai-advantage))
- **26% of all U.S. employed adults** use AI frequently (at least a few times per week) ([Gallup Q4 2025](https://www.gallup.com/workplace/701195/frequent-workplace-continued-rise.aspx))

**By demographic:**
- Adults under 50: Around half use AI about once a day or more ([Pew, Jun 2025 survey per Mar 2026 summary](https://www.pewresearch.org/short-reads/2026/03/12/key-findings-about-how-americans-view-artificial-intelligence/))
- Millennials (ages 28–43): Most likely to use AI daily among desk workers (33%), edging out Gen Z (28%) ([Slack survey](https://slack.com/blog/news/the-new-ai-advantage))
- Male workers outpace female: 24% of men vs. 18% of women are daily AI users among desk workers ([Slack survey](https://slack.com/blog/news/the-new-ai-advantage))
- Executives: 43% of executives use AI daily vs. 10% of individual contributors ([Slack survey](https://slack.com/blog/news/the-new-ai-advantage))

**Gallup industry breakdown (Q4 2025):**

| Industry | Total AI Use | Frequent Use | Daily Use |
|----------|-------------|--------------|-----------|
| Technology | 77% | 57% | 31% |
| Finance | 64% | ~40% | ~16% |
| College/university | 63% | — | — |
| Professional services | 62% | 36% | 16% |
| K-12 education | 56% | — | — |
| Healthcare | ~41–43% | — | — |
| Government | ~41–43% | — | — |
| Manufacturing | ~41–43% | — | — |

### 2d. Power Users / Builders (Daily, Multi-Tool)

There is no agreed definition of "AI power user" in the literature. Several data points triangulate the segment:

**Size estimates:**
- **5%** of all employees (globally, 15,000-person survey) are maximizing AI to transform their work — EY's definition of advanced/power users ([EY Work Reimagined 2025](https://www.ey.com/en_gl/newsroom/2025/11/ey-survey-reveals-companies-are-missing-out-on-up-to-40-percent-of-ai-productivity-gains-due-to-gaps-in-talent-strategy))
- **12%** of U.S. employed adults use AI daily ([Gallup Q4 2025](https://www.gallup.com/workplace/701195/frequent-workplace-continued-rise.aspx))
- **13%** of employees self-report using gen AI for >30% of their daily work (McKinsey's implicit "heavy user" threshold) ([McKinsey AI in the Workplace 2025](https://www.mckinsey.com/capabilities/tech-and-ai/our-insights/superagency-in-the-workplace-empowering-people-to-unlock-ais-full-potential-at-work))
- **19–20%** of U.S. adults use AI every day ([Menlo Ventures, State of Consumer AI](https://menlovc.com/perspective/2025-the-state-of-consumer-ai/))
- **43% of executives** use AI daily, vs. **10% of individual contributors** ([Slack survey](https://slack.com/blog/news/the-new-ai-advantage))

**What separates power users:**
- EY's advanced users (5%) save an extra 1.5 days of productivity per week vs. basic users ([EY, per Inc. Magazine](https://www.inc.com/kolawole-adebayo/ai-power-users-are-rapidly-outpacing-their-peers-heres-what-theyre-doing-differently/91298311))
- 88% of employees use AI for basic tasks (search, summarization); only 5% use it in advanced ways to transform work ([EY Work Reimagined 2025](https://www.ey.com/en_gl/newsroom/2025/11/ey-survey-reveals-companies-are-missing-out-on-up-to-40-percent-of-ai-productivity-gains-due-to-gaps-in-talent-strategy))
- Daily users report 64% higher productivity, 58% better focus, 81% greater job satisfaction ([Slack survey](https://slack.com/blog/news/the-new-ai-advantage)) — though this is from a Slack-surveyed population with strong selection bias

**Multi-tool behavior:**
- Workers who use AI tools both inside and outside their work systems toggle between an **average of 4 different AI options** ([Salesforce/YouGov survey, Jan 2026](https://www.salesforce.com/news/stories/ai-tools-lack-job-context/))
- 35% of developers use 6–10 distinct tools to get their work done ([Stack Overflow Developer Survey 2025](https://stackoverflow.blog/2025/12/29/developers-remain-willing-but-reluctant-to-use-ai-the-2025-developer-survey-results-are-here/))
- 60% of consumers use both general AI assistants and specialized AI tools ([Menlo Ventures, State of Consumer AI](https://menlovc.com/perspective/2025-the-state-of-consumer-ai/))

**Power user demographics:**
- Skew: Male, executive/management level, Millennials, higher education, tech/finance industries
- Gallup: Leaders have gone from 17% frequent use in Q2 2023 to **44%** in Q4 2025; managers from 15% to **30%**; individual contributors from 9% to **23%** ([Gallup Q4 2025](https://www.gallup.com/workplace/701195/frequent-workplace-continued-rise.aspx))

---

### 2e. Enterprise Employees: Org-Mandated AI vs. Shadow AI

**Organizational deployment status (Gallup Q4 2025):**
- 38% of employees say their org has integrated AI for productivity/quality
- 41% say their org has NOT implemented AI tools
- 21% don't know

Source: [Gallup Q4 2025](https://www.gallup.com/workplace/701195/frequent-workplace-continued-rise.aspx)

**How many tools does a typical enterprise deploy?**
Direct "average number of AI tools per org" data is scarce. Proxy metrics:

- Over 50 AI products now generate >$100M ARR — indicating massive enterprise tool proliferation ([Menlo Ventures, State of Enterprise AI 2025](https://menlovc.com/perspective/2025-the-state-of-generative-ai-in-the-enterprise/))
- McKinsey: More than half of enterprises report using AI in 3+ business functions; more than two-thirds in 2+ functions ([McKinsey State of AI 2025](https://www.mckinsey.com/capabilities/quantumblack/our-insights/the-state-of-ai))
- Organizations average 490 SaaS applications total; 47% are authorized, implying ~259 are unsanctioned ([Reco, 2025 State of Shadow AI](https://www.reco.ai/state-of-shadow-ai-report))

**The Shadow AI problem:**

Shadow AI = employees using unsanctioned AI tools, often through personal accounts.

| Metric | Stat | Source |
|--------|------|--------|
| Employees bringing own AI tools to work (global, across sectors) | 23%–58% | [EY Work Reimagined 2025](https://www.ey.com/en_gl/newsroom/2025/11/ey-survey-reveals-companies-are-missing-out-on-up-to-40-percent-of-ai-productivity-gains-due-to-gaps-in-talent-strategy) |
| Employees admitted using unsanctioned AI agents | 29% | [Microsoft Cyber Pulse report, via Beam.ai](https://beam.ai/agentic-insights/ai-agent-sprawl-new-shadow-it) |
| Average shadow AI incidents per company per month | 223 | [Gravitee State of AI Agent Security 2026, via Beam.ai](https://beam.ai/agentic-insights/ai-agent-sprawl-new-shadow-it) |
| Shadow AI tools per 1,000 employees (small businesses) | 269 | [Reco, 2025 State of Shadow AI](https://www.reco.ai/state-of-shadow-ai-report) |
| Employees in small firms (11–50 workers) using unsanctioned tools | 27% | [Reco, 2025 State of Shadow AI](https://www.reco.ai/state-of-shadow-ai-report) |
| AI agents operating in corporations without monitoring | ~1.5 million | [Gravitee State of AI Agent Security 2026, via Beam.ai](https://beam.ai/agentic-insights/ai-agent-sprawl-new-shadow-it) |
| Fortune 500 companies with active AI agents deployed | 80% | [Microsoft Cyber Pulse report, via Beam.ai](https://beam.ai/agentic-insights/ai-agent-sprawl-new-shadow-it) |
| Consumer AI spend that is work-related but paid personally (PLG/shadow) | ~27% of ChatGPT Plus type subscriptions | [Menlo Ventures, State of Enterprise AI 2025](https://menlovc.com/perspective/2025-the-state-of-generative-ai-in-the-enterprise/) |
| How long unsanctioned AI tools persist in workflows | 400+ days | [Reco, 2025 State of Shadow AI](https://www.reco.ai/state-of-shadow-ai-report) |

**Shadow AI caveat:** Reco is a security vendor with commercial interest in amplifying shadow AI concerns. The 269 tools per 1,000 employees figure needs contextual interpretation — it likely includes all AI-enabled SaaS features, not just standalone AI tools.

## 4. Tool Sprawl: How Many AI Tools Are In Use?

### 4a. Individual Level

- Workers toggling between AI tools (inside and outside work systems): average of **4 different AI options** ([Salesforce/YouGov, Jan 2026](https://www.salesforce.com/news/stories/ai-tools-lack-job-context/))
- 60% of consumers use both general AI assistants and specialized AI tools ([Menlo Ventures, State of Consumer AI](https://menlovc.com/perspective/2025-the-state-of-consumer-ai/))
- Developers use 6–10 distinct tools to complete work (35% of respondents fall in this range) ([Stack Overflow 2025](https://stackoverflow.blog/2025/12/29/developers-remain-willing-but-reluctant-to-use-ai-the-2025-developer-survey-results-are-here/))
- 91% of AI users reach for a general AI tool for nearly every task, but specialized tools are supplementary ([Menlo Ventures, State of Consumer AI](https://menlovc.com/perspective/2025-the-state-of-consumer-ai/))

### 4b. Enterprise Level

- Total SaaS applications per organization: ~490 (about 47% authorized, 53% unauthorized) ([Reco 2025 Shadow AI Report](https://www.reco.ai/state-of-shadow-ai-report))
- Shadow AI tools per 1,000 employees (small firms): 269 ([Reco 2025](https://www.reco.ai/state-of-shadow-ai-report))
- More than 50 AI products now generate >$100M ARR, 10+ generate >$1B ARR ([Menlo Ventures, State of Enterprise AI 2025](https://menlovc.com/perspective/2025-the-state-of-generative-ai-in-the-enterprise/))
- McKinsey: AI high performers use AI in more business functions; half of all respondents use AI in 3+ functions ([McKinsey State of AI 2025](https://www.mckinsey.com/capabilities/quantumblack/our-insights/the-state-of-ai))

### 4c. Enterprise AI Spend Breakdown (Market-Sizing Proxy for Tool Categories)

From Menlo Ventures 2025 enterprise survey (n=~500, U.S. enterprise decision-makers):

| Category | 2025 Spend | YoY Growth |
|----------|------------|------------|
| Total generative AI | $37B | 3.2x |
| Coding tools | $4.0B (55% of departmental AI) | — |
| IT operations | $700M | — |
| Marketing platforms | $660M | — |
| Customer success tools | $630M | — |
| Design | ~$540M | — |
| HR | ~$390M | — |

Source: [Menlo Ventures, State of Enterprise AI 2025](https://menlovc.com/perspective/2025-the-state-of-generative-ai-in-the-enterprise/)

Departmental AI spend hit $7.3B in 2025 (up 4.1x YoY), confirming rapid multi-tool deployment across enterprise functions.

**Key insight on tool sprawl:** 27% of all AI application spend in enterprises comes through product-led growth (PLG) motions — employees trying tools on their own before IT sanctions them. This is nearly 4x the rate in traditional software (7%). When shadow AI adoption is factored in, PLG-driven tools may represent close to 40% of application AI spend. ([Menlo Ventures](https://menlovc.com/perspective/2025-the-state-of-generative-ai-in-the-enterprise/))

**Enterprise LLM market share (for teams building on APIs):**
- Anthropic: 40% (up from 24%)
- OpenAI: 27% (down from 50%)
- Google: 21% (up from 7%)

1. Writing boilerplate and repetitive code
2. Searching for development-related information
3. Converting code to other languages
4. Writing code comments or documentation
5. Summarizing recent code changes

Source: [Stack Overflow Developer Survey 2025](https://survey.stackoverflow.co/2025/ai)

### 5d. AI-Generated Code Volume

- 41% of all code is now AI-generated ([GitHub/Anthropic data cited by EliteBrains](https://www.elitebrains.com/blog/aI-generated-code-statistics-2025))
- Google: Over a quarter of new code generated by AI (per CEO Sundar Pichai)
- 50% of developers in enterprises use AI coding tools daily (65% in top-quartile organizations) ([Menlo Ventures, State of Enterprise AI 2025](https://menlovc.com/perspective/2025-the-state-of-generative-ai-in-the-enterprise/))
- Teams report 15%+ velocity gains across software development lifecycle ([Menlo Ventures, State of Enterprise AI 2025](https://menlovc.com/perspective/2025-the-state-of-generative-ai-in-the-enterprise/))

### 5e. Developer Sentiment and Trust

**Stack Overflow 2025 — a nuanced picture:**
- Positive sentiment for AI tools: dropped from 70%+ in 2023/2024 to **60%** in 2025
- More developers actively **distrust** AI accuracy (46%) than trust it (33%)
- Only 3% "highly trust" AI output
- Experienced developers most cautious: 2.6% "highly trust" / 20% "highly distrust"
- Top frustration (66%): "AI solutions that are almost right, but not quite"
- 75% would still ask a human for help when they don't trust AI's answer

Source: [Stack Overflow Developer Survey 2025 blog](https://stackoverflow.blog/2025/12/29/developers-remain-willing-but-reluctant-to-use-ai-the-2025-developer-survey-results-are-here/)

**The trust/use paradox:** More developers are using AI tools than ever, but trust has declined as experience accumulates. The dominant frustration is not that AI can't code — it's that AI produces plausible-but-wrong code that costs time to debug. This is especially acute for experienced developers who have the judgment to detect errors.

### 5f. AI Agents in Development (Still Early)

- 52% of developers either don't use agents or stick to simpler AI tools ([Stack Overflow 2025](https://survey.stackoverflow.co/2025/ai))
- 38% have no plans to adopt agents
- 72% say "vibe coding" (generating entire apps from prompts) is not part of their professional work
- Among those using agents: 69% agree agents increased productivity

## 6. Summary Segmentation Table

| Segment | Est. % of U.S. Adults | Est. % of Knowledge Workers | Key Characteristics |
|---------|----------------------|----------------------------|---------------------|
| **Non-users / Skeptics** | ~39% | ~20–25% | Older, lower-income, frontline workers; distrust, no perceived need |
| **Dabblers** (a few times/year) | ~20–25% | ~15–20% | Casual, task-specific; mainly search, summarization, one-off writing |
| **Mainstream weekly users** | ~25–30% | ~40–45% | Multiple tasks weekly; writing, research, email; 2–4 tools |
| **Power users** (daily, multi-tool) | ~15–20% | ~20–25% | 4+ tools; AI integrated into workflow; transformative use |
| **Advanced builders** (daily + custom/agentic) | ~3–5% | ~5–10% | API users, custom workflows, agents; primarily tech sector |

**Note on estimates:** These ranges are synthesized from Gallup, Pew, Menlo Ventures, EY, Slack, and SSRS data. No single survey cleanly defines these segments. The ranges reflect meaningful uncertainty.

## 7. Cross-Cutting Observations

**The gap between "using AI" and "deriving value from AI" is large.** EY found 88% of employees use AI, but 95% are stuck on basic tasks (search, summarization). Only 5% are transforming their work. McKinsey found that 88% of organizations have AI deployed in at least one function, but only a third are scaling — and only 39% report any EBIT impact.

**Adoption growth is plateauing at the broad population level, while deepening among current users.** Gallup's overall user count was flat in Q4 2025 after sharp increases earlier in the year. But frequency of use among existing users continued to rise. This suggests AI adoption may be approaching saturation in certain demographics while still accelerating in knowledge-worker roles.

**Remote and knowledge work = AI work.** Gallup's data is stark: remote-capable workers have 66% total AI use; non-remote workers have 32%. The AI productivity story is largely a desk-worker story so far.

**Enterprise vs. personal AI are two different markets.** Enterprises are predominantly deploying coding tools ($4B), copilots ($7.2B), and customer-facing automation. Consumers primarily use general chat assistants (ChatGPT dominates at 70% of consumer spend). The enterprise is far more concentrated in specific use cases.

**Developer adoption is the leading indicator.** Developers have the highest documented daily AI usage (51% daily per Stack Overflow), the most tool diversity, and the clearest ROI signals (15%+ velocity gains, 41% AI-generated code). The developer segment forecasts where general knowledge workers will be in 12–24 months.
