In a revelation that has sent shockwaves through the global tech industry, Anthropic’s Chief Product Officer, Mike Krieger, confirmed on February 9, 2026, that the company’s internal software development is now effectively 100% automated. Speaking at the Cisco AI Summit, the former Instagram co-founder stated that the paradigm has shifted from AI assisting humans to “Claude writing Claude.”
This milestone surpasses the bold prediction made by CEO Dario Amodei just a year ago, who estimated that 90% of code would be AI-generated by 2026.
The New Workflow: Scaffolding and Supervision
According to Krieger, the role of the human software engineer at Anthropic has undergone a fundamental transformation. Instead of typing lines of code, engineers now act as high-level architects and adversarial reviewers.
- Massive Pull Requests: Internal teams are now routinely producing 2,000 to 3,000-line pull requests generated entirely by AI.
- Trust Through Scaffolding: To manage this volume, Anthropic has built “scaffolds”—automated testing and validation frameworks—that allow the company to trust machine-generated code at scale.
- Adversarial Review: Engineers use Claude to review the code Claude wrote. The AI is prompted to act as a “super tough grader,” identifying security vulnerabilities and suggesting refactors before any code reaches production.
Economic Impact: The “SaaSpocalypse”
The news of Anthropic’s internal efficiency—combined with the launch of Claude Cowork and Claude Code—triggered what market analysts are calling the “SaaSpocalypse.” On February 10, 2026, global markets saw a massive sell-off of traditional software and IT services stocks. Investors are increasingly worried that if AI can write 100% of the code for a $380 billion frontier lab, the traditional headcount-heavy business models of IT giants are facing obsolescence.
| Sector Hit | Impact Detail |
| Indian IT Services | TCS, Infosys, and HCLTech saw steepest single-day declines in months. |
| Traditional SaaS | Salesforce, Adobe, and ServiceNow faced multiple compression as AI agents target their core workflows. |
| Developer Tools | Markets are pricing in a shift where AI doesn’t just support software; it replaces the need for the middle layers. |
The “12-Month” Warning
Reiterating a warning he gave at Davos earlier this year, CEO Dario Amodei suggested that software engineering as a profession could be completely obsolete within 6 to 12 months.
“I have engineering leads who have basically said to me, ‘I don’t write any code anymore. I just let Opus do the work and I edit it.'” — Dario Amodei, Anthropic CEO.
While some industry veterans, including Zoho’s Sridhar Vembu, have urged engineers to look for “alternate careers,” others argue that this shift simply moves the human value further up the stack—to problem definition, system design, and ethical oversight.
