Silicon Valley is entering what AI leaders call the “centaur phase,” where human engineers paired with autonomous AI agents are dramatically accelerating software development, according to industry executives and investors.
Dario Amodei, CEO of Anthropic, says this hybrid stage allows humans and AI to outperform either working alone, though he believes it may last only a few years before AI systems operate independently.
The shift is most visible in software engineering, where agent-based tools can complete weeks of work in minutes.

Momentum surged after the rise of OpenClaw, an open-source platform that allows AI agents to plan, code, and deploy software autonomously.
Its creator, Peter Steinberger, was later hired by OpenAI, whose CEO Sam Altman called agents central to future products.
Investors and startups are racing to adopt the technology, though security risks and high technical barriers remain.
