The question of whether and when AI will begin to replace human labor has long been a subject of intense debate. Researchers at SignalFire, a data-driven venture capital firm that tracks workforce trends across more than 600 million professionals and 80 million companies on LinkedIn, believe they may be witnessing the initial signs of AI’s impact on employment dynamics.
Drawing on data from its Beacon AI platform, which tracks over 650 million professionals and 80 million organizations, the report highlights a dramatic downturn in new graduate hiring, the strategic dominance of elite AI labs like Anthropic in talent retention, and a significant reshuffling of geographic tech power centers.
Over the last few years, the competition for tech and AI talent has been nothing short of fierce. SignalFire’s latest analysis is about deep, structural changes. While headlines often focus on layoffs or the remote work debate, the data points to a more nuanced story of how, where, and who companies are hiring to build the next generation of technology.
Tech’s “lost generation”Perhaps one of the most alarming trends identified in the report is the collapse of entry-level hiring. The door to the tech industry, once wide open for new graduates, is now “barely cracked.” This shift is attributed to a confluence of factors: smaller funding rounds for startups, shrinking team sizes, a reduction in new grad programs, and the increasing capabilities of AI automating routine tasks.
The numbers are sobering:
The report notes that while hiring bounced back in 2024 for mid- and senior-level roles after a general dip in 2023, the cuts for new graduates have only deepened. Data from the Federal Reserve Bank of New York corroborates this, showing a 30% rise in the unemployment rate for new college grads since September 2022, compared to an 18% rise for all workers. Perceptions aren’t helping either: 55% of employers state that Gen Z struggles with teamwork, and a striking 37% of managers admit they would rather use AI than hire a Gen Z employee.
This “experience paradox” means that even top computer science graduates are finding it difficult to break into the industry, especially at the “Magnificent Seven” (Alphabet, Amazon, Apple, Meta, Microsoft, NVIDIA, and Tesla), where the share of new graduates landing roles has more than halved since 2022. Companies are now prioritizing proven experience over potential, posting junior roles but often filling them with more senior individuals.
While AI often takes the blame for eliminating junior positions, SignalFire suggests the reality is more complex. The end of the low-interest “free money madness” of 2020-2022, leading to overhiring and subsequent corrections, is a major driver. With tighter budgets, companies are hiring leaner. Carta data shows Series A tech startups are, on average, 20% smaller than in 2020. This isn’t just about hiring less; it’s a “hiring reset,” with a focus on roles delivering high-leverage technical output, particularly in machine learning and data engineering, while non-technical roles in recruiting, product, and sales continue to shrink.
Anthropic sets a blistering pace in retentionThe launch of ChatGPT in November 2022 didn’t just usher in a new era of AI; it ignited an intense AI talent race. SignalFire’s analysis of retention across top AI labs reveals a clear leader: Anthropic. An impressive 80% of employees hired at Anthropic at least two years prior were still with the company at the end of their second year. This stands in stark contrast to an industry known for high turnover. DeepMind follows closely with a 78% retention rate, while OpenAI’s retention is lower at 67%, though still on par with large FAANG companies like Meta (64%).
Anthropic’s success isn’t just about keeping talent; it’s about strategically acquiring it. The report highlights:
Big Tech companies like Google, Meta, Microsoft, Amazon, and Stripe have also become prime hunting grounds for AI labs, with Anthropic being particularly successful in attracting senior researchers and engineers from these established players.
The geographic distribution of tech talent is also in flux. While San Francisco and New York City remain dominant (hosting over 65% of AI engineers), other hubs are making significant gains. The report notes key trends from 2024:
This isn’t merely regional reshuffling. Companies are adopting a “proximity over presence” model, valuing closeness for hybrid schedules and anchor days over strict five-days-a-week office mandates, leading to a surge in in-state hiring.
41% of Gen Z workers are sabotaging their employer’s AI plans
SignalFire revisited its predictions from the previous year, noting successes like the persistence of fractional work, continued growth in cybersecurity talent demand, and the evolution of remote work into hybrid models. For 2025, the report forecasts several key developments:
The overarching message of the SignalFire report is that “technology alone doesn’t build the future, people do.”
