Short answer: Probably not. By 2100, advanced AI will almost certainly be deeply embedded in society and governance, but a single AGI “ruling the world” is unlikely.

A compact forecast (subjective, with wide uncertainty):
- AGI exists by 2100 (human-level general capability across most tasks): moderate-to-high chance, roughly 60–85%.
- AGI (or a single AI-backed actor) attains global, unilateral control: low chance, perhaps 2–10%.
- AI drives major concentration of power (a few states or firms gain outsized influence without total control): moderate chance, maybe 20–40%.

Why “ruling the world” is unlikely:
- Multipolar development: Many labs, nations, and regulatory regimes make monopoly control hard.
- Governance and safety efforts: Standards, audits, and international coordination are ramping up, which can check unilateral dominance.
- Societal pushback: Democracies, civil society, and markets resist ceding full sovereignty to machines or single actors.

What could increase the risk:
- A decisive technical lead (e.g., a breakthrough + massive compute advantage) by one actor.
- Weak global governance, unsafe race dynamics, or severe misalignment failures.
- Authoritarian adoption of AI to entrench control.

Most plausible 2100 outcome:
- AI is pervasive, powerful, and a key part of decision-making, but embedded in human institutions with legal and technical guardrails—uneven across countries.

If you want, I can:
- Break down scenarios in more detail.
- Point to recent expert surveys and community forecasts.
- Outline concrete governance and safety measures that reduce concentration and takeover risks.
