  • This is your brain on drugs…. Cocaine on the left, Group-belonging on the right. Todd Rose, far right

    Todd Rose, Author of Collective Illusions: "Why do people lie in public, contrary to their private beliefs? One word: Belonging. The fMRI brain imaging of a drug addict given cocaine lights up the reward system. When people are told their beliefs align with their group, it activates the exact same reward system. To wreak havoc… Read More

  • Is intelligence substrate-dependent?

    Neuroscience Prof. Anil Seth argues that conscious human intelligence is tightly coupled to our living, biological substrate, not replicable or simulatable in silicon. Here are some of my reactions to his thought-provoking piece: If human intelligence and consciousness is substrate dependent, as asserted, even down to individual neurons being irreplaceable by silicon substrates, then some… Read More

  • We got the MEAT 🎶 the new book by Bruce Friedrich

    Just got my pre-print of “a road map to a better future for meat manufacturing… where our appetites and our ethics can finally align.” — my blurb in the book 🙂 Some of the technologies covered: • Cellular Ag: grow real meat without the animal, “indistinguishable from conventional animal meat, but less expensive, more nutritious,… Read More

  • Miami Mermaid Manatee

    Saw one for the first time in the wild. Here are three cool things about them: • Genetically, their closest relative is the elephant. Notice the grey wrinkled skin. Whales evolved from a wolf-like land animal, and seals came from a bear-like ancestor. All marine mammals evolved from land animals, so in the long arc… Read More

  • The Shifting Sands of Liberty

    one of the many Sisyphus sand sculptures. The perfect gift for a beach house. One big marble makes the finest filigree.

  • 🔴 Passing through the Gateway to Mars

    I was inside the new Starbase building for a board meeting, a looming reminder of the mission overhead. Mars is a good substrate for making humans. It has plenty of carbon for making food for a growing population (the atmosphere is 95% CO2, with nitrogen too). And that’s essential for making humanity independently multiplanetary. The… Read More
