Life 3.0
What kind of future would we want intelligence to make possible?
Compare three possible worldsWho gets to decide?
Who shares in the benefits?
What makes a life worth living?
Capability opens the question. Values keep it open.
Max Tegmark uses the possibility of advanced artificial intelligence to ask how life might change. The book moves between technical ideas, speculative stories, and questions about work, power, goals, and consciousness.
Its future scenarios give readers contrasting arrangements to examine. Consider who holds authority, what people can choose, and how benefits are shared. A world can sound attractive in one respect while leaving a difficult question elsewhere.
Read the scenarios as thought experiments. Their purpose here is to make assumptions discussable. The book’s vocabulary and imagined worlds are presented in their 2017 context.
See the publisher’s introduction and excerpt and the Future of Life Institute’s scenario guide. All discussion prompts below are original HourLife questions.
What can life change about itself?
Life 2.0: Cultural
- Hardware: physical form
- Shaped through evolution
- Software: abilities and behavior
- Can change through learning
Life 3.0: Technological
- Hardware: physical form
- Could be redesigned
- Software: abilities and behavior
- Could be redesigned
A condensed guide to Tegmark’s terms. Life 3.0 is the book’s proposed technological category, not a label for today’s chatbots.
Put two possible worlds beside each other
Choose two of the book’s twelve scenarios, then ask the same question of each. The short summaries describe Tegmark’s imagined arrangements; the prompts invite your own judgment.
Different forms of intelligence coexist peacefully in a world organized around property rights.
Who can challenge the arrangement?
Consider the rules, who can change them, and what a person could do if they disagreed.
Humans, cyborgs, and uploads coexist peacefully with property abolished and an income guaranteed.
Who can challenge the arrangement?
Consider the rules, who can change them, and what a person could do if they disagreed.
Two contrasting worlds. Look for the assumption each one asks you to accept.
Scenario names and condensed descriptions follow the published 2017 guide. This comparison assigns no probabilities or arrival dates.
Does the goal say what you mean?
Tegmark’s discussion of goal alignment asks how a powerful system could pursue an objective while missing human intentions. Try the gap on an ordinary fictional task.
Based on Tegmark’s book excerpt on aligning goals. These examples are original exercises in specifying a task.
Increase visits to the library
A library asks a system to maximize the number of visits each month.
What could raise the count without helping readers?
A result the count could miss
A question for a better brief
Adding a sentence does not solve AI alignment. This exercise helps expose an assumption in an objective.
Questions readers carry into the future
Reader summaries of the book’s ideas, kept separate from forecasts and author quotations.
A capable system can pursue a poorly chosen objective.
Tegmark’s alignment discussion separates the ability to achieve a goal from whether the goal reflects human intentions. Ask what a successful measurement might leave out.
The three stages describe what life can redesign.
The book distinguishes evolution-shaped life, life that learns and changes its behavior, and a proposed technological stage able to redesign physical form as well as abilities.
A future scenario makes values and assumptions visible.
Read each imagined world for who holds power, what people can choose, and how resources are shared. Its appeal may depend on an assumption you would want to question.
Intelligence and consciousness raise different questions.
Accomplishing a task and having subjective experience are different ideas. When an argument moves between them, identify what evidence or assumption supports the move.
A plausible story still needs its assumptions examined.
A detailed scenario can be easy to picture without establishing when or whether it will occur. Separate the imagined arrangement from a forecast and ask what would have to be true.
The distribution of benefits is part of the design question.
Ask who could use a technology, who would own or govern it, and how a person affected by a decision could respond. Technical capability alone leaves those questions open.
Make an abstract future discussable
Original practices for examining a scenario, a goal, and the values behind an argument.
Compare the rules of two imagined worlds
Choose two scenarios from the book. For each, name who decides, who benefits, and how a person could disagree. Identify an assumption you accept in one world and question in the other.
Check an objective against a real experience
Return to a goal you have written. Ask someone affected by it what the measurement misses. Record one change to the brief and a way for the person to report a problem.
Find a loophole in an ordinary objective
Write a measurable goal for a familiar task. Invent one way to improve the measurement while making the real experience worse. Add the missing consideration and name who could review the result.
Return to a scenario with a new question
Revisit a future you initially liked. Ask what everyday life might be like for someone with less power, different access needs, or a wish to live differently. Note what the scenario leaves unspecified.
Separate a capability claim from an experience claim
Take an argument about AI and mark statements about accomplishing tasks separately from statements about consciousness. Write what would support each claim and where the argument remains uncertain.
Trace one automated decision you encounter
Choose an actual service you use and read its explanation of a relevant automated feature. Note what information it uses, what choice you retain, and where you can ask a question or challenge a result.
Read one alignment argument at its source
Choose a clearly attributed argument about goal alignment, such as Tegmark’s published book excerpt. Write the objective, the proposed failure, and the assumption that connects them. Keep your interpretation separate.
Discuss a value conflict in a future scenario
Choose one imagined world and invite a willing reader to discuss a difficult tradeoff in it. Each person names a value they want protected and a decision that might put it under pressure.
