The third era of AI software development · Cursor

Cursor's CEO outlines three eras of AI-assisted software development: tab autocomplete, synchronous prompt-and-response agents, and now autonomous cloud agents that work independently over longer timescales. Cursor reports that agent users now outnumber tab users 2:1, and 35% of internal PRs are created by autonomous agents running in cloud VMs. The vision is developers acting as directors—defining problems, reviewing artifacts, and running multiple agents in parallel—rather than writing code line by line. Cursor's newly launched cloud agents are positioned as the first step toward this model.
