MODULE 6: Radical Life Extension

Review Monday
  • Come with questions!
_________________________

 






Two questions Fischer and Cave ask

  1. Would RLE 6000 be good for you? (prudential question)
  2. Would RLE 6000 be good for us? (question about ethics, justice)
Cave on the second question: 
  1. If everyone took, then there would be a huge population increase (see graphs below)
  2. If it was restricted to the rich .... social injustice 
  3. If there were limits on childbearing .... social injustice
Fischer: limit to the rich OR have a lottery, but no limits on reproduction (Cave and Fischer Part 2, ch. 4, p. 150-154)

Let's explore these questions about distribution, but switch to RLE200


  • RLE200 eliminates aging, cancer, heart disease, etc.
  • enough to make the lifespan 200 years on average, not 6000
  • suppose we really had RLE200
  • how should it be distributed?  WORKBOOK
  • after we discuss, we will vote using this poll


ChatGPT prompt: what would be the population
10,000 years from now if people reproduced
 at replacement level and lived for 6000 years?
