Jensen Huang, CEO of Nvidia:
"People are teaching their agents to fully run a business and make money."
Support. Sales. Operations. Coding. Marketing.
Agents are taking every seat at the table.
Entire companies are being compressed into workflows.
But 99% of agents still forget everything the moment a session ends.

OpenAI CEO Sam Altman:
"in the next 6 months, we're close to a world where a descendant of ChatGPT can watch your screen, record every meeting and call, and have perfect context of your whole life"
We're only one model generation away from this being incredibly useful
Chamath to a room of Stanford MBAs: "get the fucking money. I'm serious."
he says capital is a moral imperative. the money gets made and allocated either way, so if you have a worldview and none of it behind you, your view doesn't compete.
"in the absence of capital, you're irrelevant. with capital, you're powerful."
12 hrs of focused work yesterday. Surprised by the level of cognitive and mood lift.
Context switching 300x/day creates a noise floor of attention reside and chronic nervous system arousal. Microdosing cortisol.
Extended focus resensitizes, making the world interesting again
Everything in society attacks sleep. It’s humanity's greatest risk because it strips clear thinking.
Build your life around sleep. It’s worth it.
Of all the longevity stuff I’ve done, I’m most proud of my learned ability to sleep. It represents overcoming the world's dysfunctions and achieving self mastery.
Image below is last night’s perfect sleep:
. asleep in two min
. zero stress
. no rumination
. no awake
. 4hr+ restorative sleep
. 44 bpm
. body cleaned out debris and rejuvenated
Everything in society attacks sleep. Hustle culture wants you to believe if you’re sleeping more than 4 hours you’re not working hard enough. Social media wants you to feel that unless you’re performatively alerting the tribe to your existence, you don’t exist. Industrial food preys upon your late night stressed out vulnerability to glutton you with their slop. Lighting suppresses your melatonin. Screens seduce you to boil your nervous system alive. Societal angst from conflict, acrimony and meanness reverberates in your ruminations. Environmental toxins create bodily dysfunction. Stress keeps you tight as a knot.
This is why people can’t sleep.
And when people can’t sleep, emotional regulation and higher cognitive function shut down. The body can’t clear cellular debris. The body's ability to search and kill cancel cells is diminished. The immune system is suppressed. The body and mind break down, rendering zombie status.
I’ve built my life around sleep. There is no drug or therapy that is more potent for emotional stability, cognitive performance, happiness, and wisdom.
What I eat, when I eat, when I exercise, my work schedule, how I socialize, and so forth. It’s all built around sleep. It’s worth it because nothing has the power to make life better and more rich than sleep.
If you’re familiar with my work, you’ve heard me say these things hundreds of times. I’m going to say them again because people have told me that it took them hearing this 100 times before they gave it a try. Once they do, it’s a bit of an embarrassing feeling knowing that we’ve all been foolish, always knowing sleep is a good idea but then not doing it because of this or that reason.
Do these things:
Final meal 4 hours before bed.
Screens off 60 min before bed.
A 60 min wind down routine. Walk, meditate, journal, bath, talk to a friend.
Final caffeine around noon.
Avoid blue lights in the evening. Use red and amber lights.
Sunlight in eyes when waking.
The marker for your success is your resting heart rate before bed. That which increases your heart rate before bed is bad for sleep (excluding sex) and that which lowers your heart rate is good for sleep. The list above includes things that lower your heart rate and calm your nervous system.
Most importantly, it's an identity decision. Be someone who priorities sleep. People get trapped in the in-between state. They know they want it. They know it's good for them. But they're lured into the philosophies and norms of the early 21st century of sleep deprivation. Future generations will ponder
