Polsia founder Ben Cera describes a business agentAn AI agent is a system that observes context, decides what to do, and takes actions through tools to pursue a goal. that can take a high-level goal, execute routine product and marketing tasks and return creative decisions to the human operator. His broader design principle is to let AI handle repetitive work while people retain judgment, taste, messaging and strategyHuman-AI collaboration combines human judgment and accountability with AI speed, generation, analysis, and tool use in a shared workflow..
Cera argues that increasingly capable general models do not eliminate startup opportunities. Products can still differentiate through simpler interfaces, focused customer segments, speed, product choices, distribution and communication that makes AI useful outside the early-adopter technology bubble.
Cera predicts that the cost of applying AI will keep fallingInference cost is the expense of running a trained AI model to process inputs and produce outputs., even if frontier models remain expensive. He expects companies to route ordinary workflow steps to cheaper modelsAI model routing sends each request to a model chosen for that request's complexity, cost, speed, privacy, or other requirements. rather than use the most capable model for every taskModel selection chooses the AI model whose capability, quality, cost, speed, safety, and operating constraints best fit a task..
