NOTABLE RESEARCHERS JOIN $4 BILLION EFFORT TO BUILD SELF-IMPROVING AI

Recursive Superintelligence has raised more than $650 million at a valuation of more than $4 billion to build AI that can improve itself with little or no help from human developers. Its seven co-founders include notable researchers from many of the industry's leading AI companies. Many of these researchers specialize in AI systems that can run for long periods in pursuit of goals. While the researchers are bullish on the idea of AIs recursively improving themselves, the current technology is a long way from the point where humans can be removed from the loop.

THE ECONOMICS OF SUPERSTAR AI RESEARCHERS

Superstar researchers at frontier labs can earn over a hundred times more than the average AI postdoc. Researcher quantity doesn't easily make up for quality in the field of AI. Even a 2x researcher can earn far more than the median because their contributions easily scale to billions of users. If they can add something that multiple 1x researchers can't, then it's worth paying a lot to capture it.
