In 1985, Carl Sagan sat before the US Senate and described the weather of 2026. Not as a prediction. As physics.

📌 An American 🇺🇸 Indian ( "NATIVE AMERICAN ") man goes off on white
Americans ( Descendants of Illegal European immigrants) and tells them to go back to their homelands and the internet looses their mind.

前 Scale AI 创始人、刚出任 @Meta 首席 AI 官的 @alexandr_wang ，在 YC 现场跟 @garrytan 对谈时抛出这枚深水炸弹，直接把全网的技术管理层给听沉默了。
他说在 Meta 内部，我们已经真实看到了这种情况：
只要设计出正确的智能体循环（Agentic Loop），并给出一套能让它自主优化的评估系统与量化指标，
一群 AI 智能体完成的任务量，甚至超过了一支 100 名资深工程师组成的团队。
而且它们做到这一点，非常轻松，极其容易（Very easily）。”
但这场对谈最值钱、也最反直觉的地方，还不是100 个人被比下去的震撼，
而是他亲手扒开了 Meta 内部这套系统的底层骨架——
外行以为支撑这种超级蜂群的一定是极其复杂、深不可测的外星架构；
结果 Alexandr Wang 极其直白地用了几个最土的词把它打回了原型：
“Markdown files, cron jobs, goal, metrics, data.”
（Markdown 文件、定时任务、目标、指标、数据。）
撕开这层极简的包装，你会看懂这套打法对传统软件工程的降维打击：
1️⃣ 不是模型更聪明，是「闭环评估系统（Evals）」在发威：
传统的做法是人肉写提示词，祈祷模型别犯错；
Meta 的做法是把业务目标变成机器能自动验证的打分器。
模型只要敢交卷，系统自动跑测试、算指标、找坏味道；通不过就打回重做，直到绿灯亮起。
人不需要盯梢，指标本身就是最好的监工；
2️⃣ 真正的 Alpha 叫“在反馈循环里多烧 1000 倍的 Token”：
很多人用 AI 还在抠搜单次调用的价格；
顶级大厂的秘密是：宁可在后台多消耗 1000 倍甚至 100 万倍的 Token，去让 Agent 不断自查、对跑、互相对抗验证，直到把确定性的业务结果跑出来。
Token 的成本是死的，但换来的是一套永不熄火的流水线；
3️⃣ 记忆根本不需要花哨的数据库：
持久化记忆直接用 Markdown 文件存着，
调度直接用服务器自带的 Cron 定时器在夜间触发。
把脚手架做得越轻、越朴素，系统反而越皮实、越不容易出现上下文崩塌。
这是一场极度冷血的组织重塑：
过去一个技术负责人的天花板，取决于他能带多少人开会、协调多少跨部门利益；
而未来的技术领袖，唯一的生产力杠杆在于：
你能不能用最严密的数学指标，把复杂的业务目标，重述成一个连 AI 都能看得懂的自动化考卷。
当 100 个人的搬砖产能被一套定时器和 Markdown 文件轻松取代，
只会接单写代码的时代正式落幕了。
掌控评估体系、懂得调动蜂群的人，手里握着的已经不再是一个工具，而是一家随时可以原地起跳的虚拟跨国公司。

55 years of inflation
Readers added context they thought people might want to know
The 1971 $3.50 ticket admitted guests to the park only. Additional tickets were needed for each ride. Modern one-day tickets include unlimited access to rides and attractions. $3.50 in 1971 has the same buying power as about $28.50 today.

ORBIT ACHIEVED. 🚀
Vikram-1 Test Flight-1 has reached orbit. India's first privately developed orbital rocket has completed its final burn and injected its payloads into a ~450 km orbit, making India the third country in the world with private orbital launch capability.
History is made. 🇮🇳

I just learned about a concept, I can't stop thinking about.
The Four Burner Theory.
It destroyed Elon Musk's first marriage.
It explains why Bezos is jacked but divorced.
And why Zuckerberg has no real friends.
Once you understand it, your life will never be same:🧵

In 1849, Hippolyte Fizeau measured the speed of light to within 5% accuracy.
He used a rotating toothed wheel, a mirror 8.6 km away, and a candle.
Light passed through a gap in the wheel.
The wheel spun.
If it spun fast enough, the returning light was blocked by the next tooth.
The speed of rotation at the blocking point told him how long the light took to travel.
No electronics.
No lasers.
A wheel, a mirror, and arithmetic.
His result: 313,300 km/s.
Actual speed of light: 299,792 km/s.
Error: 4.5%.
For context: every measurement of the speed of light before Fizeau was either wrong by orders of magnitude or considered unmeasurable.
The experiment took place on the roof of his house in Montmartre, Paris.
He funded it himself.
He was 29 years old.
His result stood as the most accurate experimental measurement for 30 years — until Albert Michelson improved it in 1879 using a rotating mirror.
Fizeau's wheel is now in the Musée des Arts et Métiers in Paris.
The speed of light is now defined as exactly 299,792,458 m/s — not measured, but defined.
Because our measurement tools became more accurate than the definition.
Engineering eventually made physics more precise than physics could make itself.

Turns out there's a faster way to board an aircraft!
Someone should tag literally every airline and show them this.

You can't engineer luck.
Cleanest phrasing of P vs NP I've heard.
NP is the magical computer that always tells you which path to take. P is what current silicon can do. Tetris is NP-complete. Chess is EXP-complete.

If you die without a plan...
- The government takes 40% in tax
- Probate court costs $100k+
- Your kids get the scraps
If you love your family, here's every document you need to protect them:
(from a CPA & father of two)
1) Emergency Access List
This should include:
-> All bank account numbers
-> Investment account logins
-> Life insurance policies
-> 401k/IRA beneficiaries
-> Safe deposit box location
-> Password manager master code
Keep a digital & physical version for safety...
And make sure your spouse has access.
2) Legal Documents
-> Will (name guardians for kids)
-> Durable Power of Attorney
-> Healthcare Power of Attorney
-> Living Will/Healthcare Directive
Setting all of this up costs about $500...
($1,500 with an attorney)
But without them, the state decides everything.
3) Money Protection
Your family will need time to mourn.
Make sure they can do it without going broke:
-> Term life insurance (10x income)
-> Emergency fund (6-12 mo in a HYSA)
-> Retirement accounts with spouse access
4) The "First 48 Hours" Sheet
Write down clear instructions for your family:
Call this attorney: [Name/Number]
Call this CPA: [Name/Number]
File life insurance claim here: [Details]
Don't touch investments for 6 months
All bills are on autopay from [Account]
Grief destroys decision making.
This protects them.
5) Business Owner Addition
If you have a business, set up:
-> Buy sell agreements
-> Key person insurance
-> Business succession plan
-> Separate LLC owned by trust
If your company can't survive without you...
It's a 9-5 with extra steps.
6) Trust Setup
A proper trust can save your family $400k+ in probate costs.
But 90% of them are set up wrong:
-> Assets never get transferred in
-> Beneficiaries aren't updated
-> Pour-over will is missing
Here's how to fix that:
"Bulletproof" Trust System:
1) Revocable Living Trust
-> Avoids probate completely
-> Keeps finances private
-> Protects kids' inheritance
2) Pour-Over Will
-> Catches forgotten assets
3) Guardian Designation
-> Who raises your kids
-> How they get paid
Setting this up takes a weekend...
But ignoring it could cost your family everything.
So start before you're ready...
Because no one plans on dying.
Hope this helps!
Share with your spouse if you want to set this up...
And follow me for more 🤝🏻

Marc Andreessen says raw intelligence might be the worst qualification for leadership — and it changes everything about how we should think about AI.
"If the leader is more than one standard deviation of IQ away from the followers, it's a real problem."
Andreessen points to the US military, one of the earliest and most rigorous adopters of IQ testing, as the source of this insight.
They slot people into specialties and leadership roles based on IQ scores. And over the years, they kept seeing the same pattern.
A leader who is significantly less intelligent than their people struggles to model how those people think. That part is intuitive.
But the reverse turns out to be equally true.
"It's actually very hard for very smart people to model the internal thought processes of even moderately smart people."
A leader who is two standard deviations above the norm of the organisation they're running also loses theory of mind, that ability to hold an accurate model of what's happening inside someone else's head.
The gap is too wide in both directions.
Andreessen then takes this to its logical conclusion:
"If you had a person or a machine that had a thousand IQ or something like it, its understanding of reality would be so alien to the people or the things that it was managing that it wouldn't even be able to connect in any sort of realistic way."
An AI that vastly outthinks every human in the room isn't positioned to lead those humans. It's positioned to be completely incomprehensible to them.
Leadership has never really been an intelligence problem. It's a connection problem. And no amount of raw intelligence closes that gap — past a certain point, it only widens it.
The world will not be run by the smartest thing in the room for a long time. Maybe ever.
