Google DeepMind (with co-founder Shane Legg) published a paper arguing AGI is not the finish line but the starting point, mapping four pathways to ASI: compute scaling, algorithmic paradigm shifts, recursive self-improvement, and multi-agent emergence.

ASI is defined as general superhuman intelligence across virtually all domains — not narrow superhuman performance like AlphaFold or AlphaGo — and could be a collective of systems rather than a single model.

Beyond ASI is Universal AI (AIXI), a theoretical intelligence limit defined by an agent's ability to achieve goals across any imaginable environment, with hard ceilings set by physics (speed of light), computational complexity (P vs NP), and Goedel incompleteness.

Google DeepMind states it cannot easily dismiss the possibility of reaching ASI within the next decade or two even without recursive self-improvement, and that assumption gets more aggressive if an intelligence explosion occurs.

The paper cites Leopold Aschenbrenner's June 2024 'Situational Awareness' blog post directly, and Wes Roth notes that nearly every prediction in that paper — AI revenue growth, trillion-dollar GPU buildouts, national security crackdowns on AI labs — has since materialized.
