Investor Joe Lonsdale makes a nuanced geographical argument: the talent and network effects for cutting-edge AI model and cloud application startups are still concentrated in San Francisco. However, startups building in the physical world ('atoms')—like manufacturing, robotics, and defense—benefit from Texas's favorable industrial and regulatory environment.

Contrary to the post-COVID trend of tech decentralization, the intense talent and capital requirements of AI have caused a rapid re-centralization. Silicon Valley has 'snapped back' into a hyper-concentrated hub, with nearly all significant Western AI companies originating within a small geographic radius.
To find the leading edge of US reshoring, look beyond traditional industrial firms. Major technology companies like the "Mag7" are now aggressively hiring top-tier physical AI, robotics, and manufacturing talent. This signals a fundamental shift in where the most significant capital and innovation in US manufacturing are being directed.
Despite YC's push to stay in San Francisco, Hera's founders are returning to Berlin. They believe they can hire top AI talent more affordably and with less competition than in the Bay Area. Since their product is global and consumer-facing, an SF presence isn't critical for customer acquisition.
VC Joe Lonsdale argues investors are overly focused on software 'infinity stories' that could be worth trillions. Meanwhile, the 'real economy' (construction, quarrying, manufacturing) represents 85% of capital and is ripe for AI-driven transformation. These less-hyped applications represent a massive, misunderstood, and less competitive investment area.
According to Y Combinator partners, the network effects and density of talent, capital, and customers in San Francisco are so powerful that being physically based there can double a startup's chances of reaching a billion-dollar valuation compared to other major tech hubs like New York.
Instead of creating a tech sector from scratch, the most effective path is to identify and invest in tech niches adjacent to a city's existing industries (e.g., Energy Tech for an oil town). This leverages existing talent, infrastructure, and supply chains, making the transition more natural and sustainable.
Despite high-profile tech layoffs, Mayor Lurie sees a net benefit from AI because of the broader ecosystem it fosters. The job growth isn't just at giants like OpenAI, but in the enabling startups and entrepreneurs in healthcare and other sectors that are building on top of the core AI technology.
Cities like San Francisco and New York act as global talent magnets because they project a powerful and specific "whisper," or core message, about what is valued there. For S.F., it's "build a startup." This clear signal attracts ambitious individuals worldwide who are aligned with that mission.
Instead of choosing between tech hubs like Austin and San Francisco, founders can adopt a hybrid model. Spend a concentrated period (1-3 months) in a high-density talent hub like SF to build domain expertise and relationships, then apply that capital back in a lower-cost home base.
The current AI boom is uniquely concentrated within the city of San Francisco itself, rather than spread across the broader "Bay Area" or "Silicon Valley" like previous tech waves. This geographical clustering in a dense urban core has profound implications for the city's real estate, economy, and culture.
