Life 3.0
Tegmark explores possible AI futures through the capacities to redesign knowledge, goals, and eventually physical implementation.
The three life labels distinguish forms of adaptation.
A new capability changes more than what a tool can do. Tegmark asks who chooses its purposes and who bears consequences when societies become dependent on increasingly powerful systems.
Biological evolution changes inherited capacities over generations.
Cultural learning changes behaviour without waiting for genetic change.
A proposed further stage could redesign both software and implementation.
AI development raises questions about work and concentrated power.
The future scenarios are ways to reason, not announcements of what must happen. Their value depends on making assumptions explicit and preserving room for institutional choices and technical correction.
Capabilities and objectives must be analysed separately.
Beneficial outcomes require choices about institutions and design.
Consciousness and meaning remain conceptually difficult topics.
The scenarios are explorations, not established predictions.
The conclusion encourages deliberate preparation rather than assuming one inevitable future.
The conclusion encourages deliberate preparation rather than assuming one inevitable future.
If AI can transform what society can do, who chooses its purposes and who bears the consequences of dependence?
