How to Invest in Start-ups

  • A really great article by Sam Altman.
  • An interesting perspective on how to invest in winners.
  • “There is a lot of advice about how to be a good startup founder.  But there isn’t very much about how to be a good startup investor. Before going any further, I should point out that this is a particularly hard time to invest in startups—it’s easier right now to be a capital-taker than a capital-giver.”

Genetic Diversity

  • We all know about the cost of inbreeding.
  • As a result it is generally accepted that species should outbreed as much as possible – but did you know there is a cost of outbreeding as well?
  • “To produce healthy children, you should marry a third or fourth cousin. Farther out, the genetic costs of outbreeding begin to outweigh those of inbreeding. That was what a cohort study found in examining Icelanders born between 1800 and 1964. Fertility was lower if the woman’s husband was either closer in or farther out (Helgason et al. 2008).“

Animals

  • Amazing article on the human impact on animals.
  • “We breed and kill at least 100 billion animals per year for food and at least 115 million per year for research. Fishing kills 1-3 trillion animals per year. Deforestation destroys animal habitats. Leaf blowers and light pollution kill insects. Building and vehicle collisions kill at least a billion animals per year. This year, more than 300 birds were injured or killed in collisions with a building in North Carolina in a single night.“

Cancer Mortality Rates

  • New stats from the US Cancer Society show that between 1991 and 2017 the mortality rate of cancer has dropped 29%.
  • According to the report, this was due to lower smoking rates, improved early detection methods and advances in treatment.
  • This trend means more than 2.9m lives were saved since 1991.
  • Really amazing.

Dishwashers

  • Interesting article about what has been going on with dishwashers.
  • In summary they have gotten a lot worse.
  • In order to reduce water use from the original 15 gallons to 3 gallons, cycle times have increased. The chart (source) is striking.
  • The wash results have also gotten a lot worse due to chemical regulation.
  • Consumers think that by buying a newer model these problems will be solved but the reality is that an older model will do a better job.
