The AI development cycle of experimentation and bottleneck-solving is already a form of recursive self-improvement. Kyle Corbitt argues this loop is currently constrained by human intelligence. Once AIs become better at directing this process, progress will accelerate rapidly.

The vague concept of AGI is being replaced by Recursive Self-Improvement (RSI)—AI models creating their own successors. This is seen as a more specific and potentially nearer-term threshold that could trigger an uncontrolled explosion in AI progress, moving humans "out of the loop entirely."

Top researcher Andre Karpathy joined Anthropic not just as a star hire, but to lead a team using AI to accelerate AI research. This focus on "Recursive Self-Improvement" (RSI) suggests frontier labs believe they are close to a compounding loop where AIs design their successors, triggering an exponential acceleration in capability.

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.

Silicon Valley insiders, including former Google CEO Eric Schmidt, believe AI capable of improving itself without human instruction is just 2-4 years away. This shift in focus from the abstract concept of superintelligence to a specific research goal signals an imminent acceleration in AI capabilities and associated risks.

Jack Clark of Anthropic estimates a 60% probability of achieving end-to-end automated AI R&D by 2028. This "recursive self-improvement," where AI designs better AI, would mark a critical threshold, leading to an intelligence explosion and a future that is nearly impossible to forecast.

OpenAI and Anthropic's explicit strategy involves recursive self-improvement by creating AI that can perform ML research at a human level. They aim to scale this to millions of "AI researcher equivalents," believing this will accelerate progress far beyond competitors who rely on human talent.

Companies like OpenAI and Anthropic are not just building better models; their strategic goal is an "automated AI researcher." The ability for an AI to accelerate its own development is viewed as the key to getting so far ahead that no competitor can catch up.

The transition from the AI "middle game" to the "endgame" is marked by a critical shift: when top human research talent ceases to be a differentiating factor. At this point, AI progress becomes a function of an organization's existing AI capabilities and its access to compute, because the AIs themselves become the primary researchers.
