  3. Complex motor activities combining physical and cognitive demands have shown to enhance cognition.
Scaling Knowledge β€’ 117 implied HN points β€’ 30 May 23
  1. Predictions about job displacement due to large language models are often wrong because they lack explanations of how LLMs and human intelligence differ.
  2. Jobs are more likely to be augmented than automated by technologies like LLMs, as human creativity and autonomy are essential in many fields like software engineering, medicine, law, and media production.
  3. Regulations on AI and cognitive automation may hinder progress and knowledge creation, leading to unforeseen consequences and limiting the potential benefits of such technologies.
Weekly Wisdom β€’ 79 implied HN points β€’ 13 Jul 23
  1. Integral theory introduces stages of development, covering cognition, values, and identity.
  2. Stage development in integral theory involves growing up, moral development, and understanding perspectives.
  3. Integral theory categorizes levels of development using colors, from egocentric to kosmocentric stages.
Sigil β€’ 19 implied HN points β€’ 29 Dec 23
  1. The Koha model proposes that dendritic spines are computational units that scan for specific temporal codes in the brain.
  2. Excitatory and inhibitory neurons can form neural circuits that use lateral inhibition to suppress other neurons.
  3. Dendritic spines change shape to amplify or dampen signals, encoding temporal patterns and competing to become the 'winning neuron'.
Autodidact Obsessions β€’ 4 implied HN points β€’ 13 Feb 24
  1. This paper integrates various philosophic theories on language with systems like Kripke Semantics, Quantum Logic, and Mereology, encompassing all languages and symbolic logical systems.
  2. Aaron Lee's First Axiom suggests that until language is used, words exist in a state of quantum possibility, lacking fixed meanings, which challenges traditional views of semantics.
  3. The comprehensive integration of Lee's Axiom with advanced logical systems could potentially revolutionize fields like AI and computational linguistics by offering a universal framework for solving complex problems.
The Leadership Lab β€’ 39 implied HN points β€’ 04 Sep 22
  1. Using both emotion and cognition to approach problems can help you get unstuck. If you're stuck in your thoughts, focus on how you want to feel. If trapped by your feelings, think about the best path forward and take the first step.
  2. Physical movement can help you get unstuck creatively. When facing a difficult problem, go for a walk or engage in some form of physical activity without distractions. Let your body's movement guide your mind's flow.
  3. To improve as a leader, embrace your position and responsibilities. Owning your leadership means doing what needs to be done and holding yourself and others accountable. Leadership is about making hard choices but sticking to them.
