With over half of new startup pitches focusing on AI automating existing jobs, the primary solution to this massive displacement is not retraining, but fostering an ecosystem that aggressively creates new companies, new industries, and consequently, new roles.

Increased developer productivity from AI won't lead to fewer jobs. Instead, it mirrors the Jevons paradox seen with electricity: as building software becomes cheaper and faster, the demand for it will dramatically increase. This boosts investment in new projects and ultimately grows the entire software engineering industry.

Despite the hype, YC's focus isn't just on pure AI startups. The accelerator is backing a diverse portfolio of companies in healthcare, finance, and deep tech, using AI as a disruptive tool to rewrite the rules of these traditional, 'dusty' industries, much like the internet did.

AI makes tasks cheaper and faster. This increased efficiency doesn't reduce the need for workers; instead, it increases the demand for their work, as companies can now afford to do more of it. This creates a positive feedback loop that may lead to more hiring, not less.

The narrative of AI destroying jobs misses a key point: AI allows companies to 'hire software for a dollar' for tasks that were never economical to assign to humans. This will unlock new services and expand the economy, creating demand in areas that previously didn't exist.

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.

The idea that AI will enable billion-dollar companies with tiny teams is a myth. Increased productivity from AI raises the competitive bar and opens up more opportunities, compelling ambitious companies to hire more people to build more product and win.

Many engineers at large companies are cynical about AI's hype, hindering internal product development. This forces enterprises to seek external startups that can deliver functional AI solutions, creating an unprecedented opportunity for new ventures to win large customers.

Don't underestimate the size of AI opportunities. Verticals like "AI for code" or "AI for legal" are not niche markets that will be dominated by a few players. They are entire new industries that will support dozens of large, successful companies, much like the broader software industry.
