Tech Hiring Prioritizes Experience Over Skills; Shift Toward AI Data Roles
A16z's newsletter 'Chart of the Week' analyzes several tech trends based on recent data. It reports that tech job postings since January 2025 show an increased preference for experienced workers and a corresponding decrease in the number of skills required, suggesting an AI-driven shift. This trend is most pronounced in data and systems roles. The newsletter also observes that social media usage is rising, particularly among younger users, but its share of mobile screen time is declining, partially due to increased time on YouTube. Netflix's US users and viewing time have declined over three years, with a 20% drop in YouTube users who also use Netflix. Cybersecurity threats are escalating: the zero-day rate has quadrupled since 2020, and data center construction spending has surged, creating hundreds of thousands of jobs.

AI Economy Shifts Jobs Toward Skilled Trades
A CNBC feature (published 2026-05-19) argues the AI-driven expansion of data centers, chip fabs and related infrastructure is reshaping U.S. labor demand: employers are increasingly hiring skilled blue-collar workers (electricians, fiber technicians, construction trades) even as entry-level white-collar hiring slows in AI-exposed fields. AT&T, which plans a major fiber and network investment, says it cannot find enough skilled frontline technicians and is spending heavily on recruiting and training. Research from Stanford and U.S. government analysts shows early-career hiring has lagged in occupations vulnerable to AI, while economists warn of potential long-term “scarring” for recent graduates. The piece profiles workers, industry hiring incentives, and broader risks and uncertainties about how sustained the trades hiring boom will be after buildouts complete.
AI Isn't Solely to Blame for Job Scarcity
a16z's Charts of the Week analyzes recent labor-market trends and argues the decline in employment for young people is not uniquely caused by AI automation. Employment rates for both college-educated and non-college young workers have fallen similarly over the past two years. The workforce aged noticeably in 2025, driven largely by 'within-occupation' aging (people staying in jobs longer), which may limit entry-level openings. At the same time, manufacturing job openings rose slightly in early 2026 while white-collar roles continued a multi-year decline, a shift attributed in part to AI infrastructure buildouts (data centers, grid upgrades) that increase demand for construction and manufacturing workers. Goldman Sachs estimates an additional ~500K workers are needed for the buildout, leaving a ~78K labor gap. The newsletter also notes rising SMB tech spend despite flat payrolls and reports growing scarcity of on-demand GPUs per 3Fourteen Research.
Charts: Thematic Shift to AI, Infrastructure, and Agents
A16z's 'Charts of the Week' analyzes recent market and labor trends: ETFs are seeing record inflows and thematic leadership has shifted from clean energy and healthcare (2020) to AI, nuclear, space, defense, and infrastructure (2026). Data-center construction represents a large share of non-residential spending in some US states and is associated with higher local wages and job growth; Indeed and ADP data show sizable pay premiums for data-center roles. Rideshare fares (especially Uber) have risen since 2024 with platform fees and driver pay also increasing. Gig-work is growing, with social commerce expanding rapidly. On AI, token consumption and sophisticated tool adoption are concentrating in power users: top-decile firms and agents are driving disproportionate token usage, cached tokens are fueling growth, and agent usage has surged versus human usage. Early signs suggest agentic AI may disrupt legacy automation tooling.
