The computer is being reinvented in the agentic era

Greg Isenberg is a well-known startup advisor and product strategist, formerly CEO of the social audio company Racket and a partner at the venture firm Late Checkout. The "agentic era" refers to the current shift in tech toward **AI agents** — software that can act autonomously on a user's behalf (e.g., booking travel, writing code, managing tasks) rather than just responding to one-off prompts. The tweet argues that as AI agents replace traditional apps, the entire concept of a computer is being rethought: instead of opening separate programs and clicking through interfaces, users will increasingly "hire" an agent to get things done. This is part of a broader debate about whether the operating system, browser, and app-store model will be superseded by agent-driven workflows.
