Canal Mania and the Philosopher's Stone [Testμ 2026]

At Testμ Conf 2026, Sanity CEO and co-founder Magnus K. Hillestad argued that AI agents are highly capable yet unreliable because current approaches treat them too much like digital employees rather than programmable, short-lived, parallelizable systems. Drawing parallels with alchemy and the Industrial Revolution, he suggested that today’s investment in models, chips, data centers, and networking may resemble the canal-building phase that enabled later breakthroughs, while the crucial emerging challenge is creating an organizational “operating system” for human and machine work. Sanity’s experiments illustrated both potential and limitations: its multi-agent Myriad system reportedly increased some engineers’ output more than tenfold but generated excessive coordination overhead and costs exceeding $10,000 on some days, while a later direct-delegation system called Persona reduced costs by over 90% with comparable or improved output, though agents could still fail to complete delegated tasks. Hillestad concluded that effective agent systems require programmable clarity, context, checkpoints, correction, verification, and higher-level ways to express intent, leaving important open questions about coordination, non-determinism, context management, and leadership in mixed human-AI organizations.
