A five-stage ladder for AI that improves itself

The framework at the center of the claim divides self-evolving AI — systems capable of advancing on their own — into five distinct stages. Its central judgment is that today's AI occupies only the second of these levels, meaning current systems remain short of the higher stages of self-directed evolution that the taxonomy lays out.

How the check was done

Reporters went to the underlying materials directly rather than relying on secondary summaries. All nine primary sources reviewed during the fact-check were freely accessible, with no captchas, logins, or blocks standing in the way, allowing first-hand confirmation of both the five-level taxonomy and the researchers' own assessment of where current AI sits within it. Nothing in the sources reviewed contradicted the claim as it has circulated.

The claim is True.
