at the best events: people stay until the end (probably even extending the designated “end time”). everyone is chatting. people specifically go out of their way to thank the host/organizer. you’ll see two people who met at the event hang out again later.
invisible micro-management for large events 🎤and the ct scan - you don’t know if words can adequately describe the ct scan. iodine entering your veins, ice-cold at first; every blood vessel dilating at the same time; your whole body warming up from the increased blood flow; wondering am i supposed to feel this way? nobody warned me about it; the heat becoming unbearable in your arms, your head, your chest as you become convinced you will actually burn to death; all of it dissipating within seconds of exiting the machine. it is the most incredible physical sensation you have ever experienced, your first time truly feeling how your body is…

The persistence of memory - by Ashley ZhangWe can formalize “superhuman” ability in a variety of ways
An AI Which Imitates Humans Can Beat Humans | Tom Cunningham – Tom CunninghamYeah, I saw a tweet that was like, “Reminder that novels invented the internal monologue.” That’s what you get from novels that movies find relatively hard to achieve. You can see people's facial expressions and what they say, but the thing that a novel does is it lets you live inside someone's head. It conveys that people's actions and what you see on the outside is one thing, but the thing going on inside can be totally different. That’s the sort of empathy that you’re describing, and it does seem somewhat unique to the novel.

Antiqua et nova. Note on the Relationship Between Artificial Intelligence and Human Intelligence (28 January 2025)Lethal Autonomous Weapon Systems, which are capable of identifying and striking targets without direct human intervention, are a “cause for grave ethical concern” because they lack the “unique human capacity for moral judgment and ethical decision-making.
Antiqua et nova. Note on the Relationship Between Artificial Intelligence and Human Intelligence (28 January 2025)Data conveys not only information but also personal and relational knowledge, which, in an increasingly digitized context, can amount to power over the individual.
Antiqua et nova. Note on the Relationship Between Artificial Intelligence and Human Intelligence (28 January 2025)Teachers do more than convey knowledge; they model essential human qualities and inspire the joy of discovery.
Antiqua et nova. Note on the Relationship Between Artificial Intelligence and Human Intelligence (28 January 2025)such applications of AI would risk worsening the loneliness that often accompanies illness
Antiqua et nova. Note on the Relationship Between Artificial Intelligence and Human Intelligence (28 January 2025)60. Anthropomorphizing AI also poses specific challenges for the development of children, potentially encouraging them to develop patterns of interaction that treat human relationships in a transactional manner, as one would relate to a chatbot. Such habits could lead young people to see teachers as mere dispensers of information rather than as mentors who guide and nurture their intellectual and moral growth. Genuine relationships, rooted in empathy and a steadfast commitment to the good of the other, are essential and irreplaceable in fostering the full development of the human person.
Antiqua et nova. Note on the Relationship Between Artificial Intelligence and Human Intelligence (28 January 2025)Set a recurring date on your calendar to get together. And then stick to it.

Friends and relationships – Santi AranguriIf you are at a party, don’t search for the coolest person
Friends and relationships – Santi Arangurithere are no moral victories for having good thoughts or plans with no action; nothing counts until you actually start doing your chores or being nicer to people or whatever else.
unlearning - by vincent huang - a slice of my mindoh shit i shouldn’t have had that thought, and then beat themselves up over it, which is usually not healthy. meanwhile a behaviorist would simply go well, that was just a thought, you didn’t act on it, nothing to worry about here
unlearning - by vincent huang - a slice of my mindThis research could give us a clear signal like, “People in the Army consume high levels of phthalates and have high levels of infertility.

Neurovascular coupling: Motive unknown - PMCeven the baseline levels of blood flow are more than adequate to supply oxygen to neurons with elevated levels of activity
Neurovascular coupling: Motive unknown - PMCMethodological constraints caused by imagery's inherently private nature put practical limits on the types of mechanistic investigation that could be performed.

Ai to Interpret Your Mindfirst hardware breakthrough to noninvasive brain imaging
Ai to Interpret Your MindTo interface with the brain, there are two main approaches. Invasive measures involve directly interacting with the brain tissue within the skull, with things like probes and wires. Noninvasive measures involve using electromagnetic fields and radiation to map the brain, without actually touching the brain. For this newsletter, we are diving into the development of noninvasive technology.
