What exactly is an AI agent, and how will agents change the way we work?

In this episode, a16z general partners Erik Torenberg and Martin Casado sit down with Aaron Levie (CEO, Box) and Steven Sinofsky (a16z board partner; former Microsoft exec) to unpack one of the hottest debates in AI right now.

They cover:

Competing definitions of an “agent,” from background tasks to autonomous interns
Why today’s agents look less like a single AGI and more like networks of specialized sub-agents
The technical challenges of long-running, self-improving systems
How agent-driven workflows could reshape coding, productivity, and enterprise software
What history — from the early PC era to the rise of the internet — tells us about platform shifts like this one

The conversation moves from deep technical questions to big-picture implications for founders, enterprises, and the future of work.
