Researchers from Anthropic, XAI, and Google are publicly stating that Claude's advanced coding abilities feel like a form of AGI, capable of replicating a year's worth of human engineering work in just one hour.

The development of Claude Cowork demonstrates a massive acceleration in product velocity. The entire application was written by its underlying AI agent, Claude Code, in just a week and a half. This showcases how AI-driven coding is collapsing development cycles for new software products.

AI coding has advanced so rapidly that tools like Claude Code are now responsible for their own development. This signals a fundamental shift in the software engineering profession, requiring programmers to master a new, higher level of abstraction to remain effective.

The concept that AIs can build better AIs, creating an accelerating feedback loop, is no longer theoretical. Leaders from Anthropic, OpenAI, and Google DeepMind have publicly confirmed they are actively using current AI models to develop the next generation, making RSI a practical engineering pursuit.

In an extreme example of recursive development, Block's team uses their open-source AI agent, Goose, to write most of the new code for the Goose project itself. The ultimate goal is for the agent to become completely autonomous, rewriting itself from scratch for each release.

The idea of AI improving itself is already a reality at Anthropic. Over 90% of their internal code, including code for the Claude Code tool itself, is written by AI. This internal use of their own frontier models is a key driver of their accelerating development pace.

Claude Code can take a high-level goal, ask clarifying questions, and then independently work for over an hour to generate code and deploy a working website. This signals a shift from AI as a simple tool to AI as an autonomous agent capable of complex, multi-step projects.

The core task of writing code is no longer a significant challenge for AI. The focus is shifting to adjacent tasks and higher-level problem-solving, as demonstrated by Boris Cherny, who hasn't manually written code since November 2024.

The recent leap in AI coding isn't solely from a more powerful base model. The true innovation is a product layer that enables agent-like behavior: the system constantly evaluates and refines its own output, leading to far more complex and complete results than the LLM could achieve alone.
