Anthropic Engineer Boris Cherny Runs 1,000s of AI Coding Agents Overnight via Phone

Cherny said he typically keeps five to 10 Claude Code sessions open, with each session containing multiple agents and "a few thousand" handling deeper work overnight.
His setup relies on two persistent-automation features — /loops and Routines — that let users schedule recurring tasks locally or on a server after a laptop is closed.
The workflow, shown during a May 4 Sequoia Capital interview, reflects a broader shift among some Silicon Valley engineers toward using AI less as chatbots and more as always-on autonomous assistants.
A January X post in which Cherny called the setup "surprisingly vanilla" has since drawn 8.1 million views and more than 104,000 saves, suggesting strong interest in agent-based coding workflows.
When thousands of AI agents code overnight, what new catastrophic security failures are we creating?
As AI agents take over coding, is the role of a human developer shrinking to just an AI manager?
If one engineer now has a team's output, how must tech companies fundamentally restructure to survive?
