Life 3.0
Being human in the age of artificial intelligence—scenarios, risks, and choices
The Three Stages of Life
Life 1.0: Biological evolution. Hardware (body) and software (mind) evolve through natural selection over millions of years. Humans are Life 1.0—our intelligence is baked into our DNA.
Life 2.0: Cultural evolution. Hardware evolves biologically, but software evolves culturally. We learn, invent, and pass knowledge across generations. Humans are also Life 2.0—our intelligence grows through education and technology.
Life 3.0: Technological evolution. Both hardware and software are designed. AI could be Life 3.0—intelligence that redesigns its own hardware and software. This is the inflection point: once AI can improve itself, it could rapidly surpass human capability. The question isn't whether this will happen, but when—and under whose control.
Optimistic Scenario
AI solves disease, poverty, climate change. Humans focus on creativity, exploration, meaning. Life expands into the cosmos. This requires AI alignment with human values.
Pragmatic Scenario
AI transforms society gradually. Some jobs disappear, new ones emerge. Regulation evolves slowly. Wealth concentrates. We adapt, but not without disruption and inequality.
Catastrophic Scenario
AI achieves superintelligence without proper alignment. Humans lose control. Existential risk. The challenge: build safety systems before we build the systems that need them.

Community Insights

Action Steps
Conduct a '20s retrospective'
Kornhaber: what worked in your 20s? What didn't? What patterns are carrying forward? Write it as a report on the decade.
Commit to one thing fully
Kornhaber: what in your 30s deserves full commitment? Pick it. Commit. Let other things go. Half-measures produce half-lives.
Address one family pattern consciously
Kornhaber: what dynamic from your family of origin are you repeating? Name it. Own it. Choose whether to continue it.
Build one adult relationship
Kornhaber: who in your life functions as a true peer — not a parent, not a subordinate, but an adult peer? Invest in it.
Name your emerging identity
Kornhaber: in three sentences, who are you becoming? Write it. Share it with someone. The act of articulation clarifies the identity.
Invest in professional support
Kornhaber: the 30s are when you either consolidate or drift. A therapist, coach, or mentor accelerates the consolidation dramatically.
