How AI Agents Reshape Knowledge Work: Autonomy, Efficiency, and Scope

The article presents findings on the capabilities of Perplexity's Computer AI agent, which automates knowledge work more effectively than traditional search tools. It reports that Computer performs 26 minutes of autonomous work per user session compared to just 33 seconds for Search, significantly reducing task completion time from 269 to 36 minutes and lowering costs by up to 94%. This transition to autonomous agents not only enhances execution quality—evidenced by a 55% lower dissatisfaction rate—but also expands the scope of work, enabling users to engage in higher-order cognitive tasks and interdisciplinary queries.
