- Humans have always believed they are living in the end times, leading to short-term thinking and hindering the creation of a better world for future generations.
- Modern humans emerged 200,000 years ago, with a slow population growth until the agricultural and industrial revolutions significantly increased numbers.
- Currently, there are around 8 billion people on Earth, with 117 billion humans born and 109 billion dying over the last 200,000 years.
- The UN predicts a population peak around 2100, with 125 million births annually, but birth rates may not remain stable.
- The future of humanity is uncertain, with the potential for self-destruction through inventions like nuclear weapons or solutions to avert catastrophic risks.
- Scenario 1: If humans never leave Earth, with a conservative estimate of surviving for a million years, there could be roughly 100 trillion future humans.
- Scenario 2: If humans leave Earth and expand into the solar system, the potential for progress and survival increases significantly, with billions of doctors, problem solvers, and developers.
- Scenario 3: If humans colonize 100 billion stars and live for 10 billion years, generating 100 million births annually, there could be a hundred octillion future lives.
