Drawing on Cory Doctorow's insight, the immediate risk for workers isn't being replaced by a competent AI, but by an incompetent one. AI only needs to be good enough to convince a manager to fire a human, leading to a lose-lose situation of job loss and declining work quality.

Beyond simple productivity gains, AI will eliminate the need for entire service-based transactions, such as paying for basic legal documents or second medical opinions. This substitution of paid services with free AI output can act as a direct deflationary headwind, a counterintuitive effect to the typical AI-fueled growth narrative.

A critique from a SaaS entrepreneur outside the AI hype bubble suggests that current tools often just accelerate the creation of corporate fluff, like generating a 50-slide deck for a five-minute meeting. This raises questions about whether AI is creating true productivity gains or just more unnecessary work.

For current AI valuations to be realized, AI must deliver unprecedented efficiency, likely causing mass job displacement. This would disrupt the consumer economy that supports these companies, creating a fundamental contradiction where the condition for success undermines the system itself.

The narrative of AI replacing jobs is misleading. The real threat is competitive displacement. Professionals will be put out of business not by AI itself, but by more agile competitors who master AI tools to become faster, smarter, and more efficient.

In the SaaS era, a 2-year head start created a defensible product moat. In the AI era, new entrants can leverage the latest foundation models to instantly create a product on par with, or better than, an incumbent's, erasing any first-mover advantage.

For product categories where AI can easily replicate the core technology (like online file converters or headshot generators), defensibility shifts away from tech. The business becomes a pure play on marketing, distribution, and brand, much like succeeding with a new brand of canned water.

Advanced AI tools have made writing software trivially easy, erasing the traditional moat of technical execution. The new differentiators for businesses are non-technical assets like brand trust, distribution networks, and community, as the software itself has become instantly replicable.

The existential threat from large language models is greatest for apps that are essentially single-feature utilities (e.g., a keyword recommender). Complex SaaS products that solve a multifaceted "job to be done," like a CRM or error monitoring tool, are far less likely to be fully replaced.
