HERO! Flight attendant Betty Ong used her last moments on Flight 11 warning America.

Her 23 minute call was the first alert of the hijacking and gave officials the hijackers’ seat numbers, the crucial details later used to identify them and piece together the 9/11 attacks.

Never forget. 🙏🇺🇸

A Hero That Trusted His Intuition.

The problem wasn’t that Morgan Stanley didn’t believe him.

Rick Rescorla had already been right once. After the 1993 basement bombing of the World Trade Center, the firm’s security chief walked the towers, studied the site, and reached a conclusion most people preferred not to hear: the World Trade Center was still a target. Next time, he said, it would not be a truck. It would be an airplane.

An airplane. In a 1993 report.

Executives listened. Then they looked at the lease.

Morgan Stanley was the largest tenant in the complex—twenty-two floors of the South Tower, thousands of brokers, and a trading infrastructure that could not be packed into boxes and wheeled across the Hudson.

They literally made it a trading center.

The contract with the Port Authority ran until 2006. Walking away from premium Manhattan space of that scale would have meant penalties measured in the hundreds of millions, plus the operational chaos of relocating an entire downtown machine. So the company stayed.

Rescorla adjusted. If they could not leave the building, they would learn to escape it.

He built a protocol and treated it like doctrine. Unannounced drills. No exemptions. Brokers who billed by the minute were pulled off their desks and sent into the stairwells two by two, starting from the top floors, leaving a lane for firefighters coming the other way.

People complained. He did not care. Practice, he believed, was the only thing that would beat panic.

On the morning of September 11, 2001, American Airlines Flight 11 hit the North Tower. From the 44th floor of the South Tower, Rescorla could see the fire. Then the Port Authority came over the speakers: the South Tower was secure. Stay at your desks.

Rescorla grabbed a bullhorn and ignored them.

He started the drill his people already knew by heart. Floor by floor, two by two, down the stairs. He sang as he moved—Cornish songs from childhood, then “God Bless America”—keeping the line moving, refusing to let the stairwell become a stampede. Seventeen minutes later, the second plane struck the South Tower.

By then, most of Morgan Stanley was already on the way out.

Of the 2,687 employees in the building that morning, all but 13 survived.

It was stunning.

Rescorla could have been outside with them. He went back up instead. Colleagues told him to leave. He said he would, as soon as he was sure no one was left behind.

He was last seen around the 10th floor, heading higher.

The South Tower fell at 9:59 a.m. They never found him.

He was one of the 13.

He was a hero in every sense of the word.

Remember Rick Rescorla, he remembered for us.

Watch this Cybercab navigate through a very busy downtown Austin with hundreds of people around. You can see all the people the car sees on the screen.

A lot going on and it handles it all perfectly.

[Sawyer Merritt @SawyerMerritt]

Here’s my first full Cybercab ride. This vehicle is a game changer.

[Sawyer Merritt @SawyerMerritt]

I am currently in downtown Austin. There are @Tesla Cybercabs EVERYWHERE. All of the Cybercabs in these clips have no steering wheels or pedals.

Makes the vibe downtown feel so futuristic. Can’t wait for tomorrow! 🤖

[Elon Musk @elonmusk]

Cybercabs have no steering wheels or pedals. They are designed and built for maximally efficient autonomous operation.

When I first started the @honnoldfound, I was pretty much a dirtbag climber living out of my van in Yosemite and pursuing my goals in climbing. But I also knew that I wanted to do something a bit more useful in the world. So for our work at HF to be recognized by @TIME, not just because of my climbing, is pretty neat.

So far, we've committed more than $23M to support 200+ solar projects across 20+ countries, from the United States to the Amazon. But there's still a massive pipeline of need out there.

One of our main goals is to not trying to build an endowment, because there's no point in saving for some future day when there's so much potential tosupport communities, right now. Any gift we get goes straight to Partners' projects. So if you're someone who wants to see some good happen in the world, consider making a donation to HF, and we'll keep funding more good work.

You can also read the full article to learn more about HF's latest work and hear a few examples from our partner projects. 

Oh, and It feels important to mention that the real trailblazers are the community leaders who champion solar solutions in their communities.

Dyson trained an AI on 470,000 dental images and put it inside a toothbrush. With a camera. That flosses for you. In real time.

It's called the CameraJet for $499. Launched today.

A 100,000-pixel macro lens sits inside the brush head. It takes 28 images per second while you brush. The AI detects gaps between your teeth and within 100 milliseconds fires a precision jet of mouthrinse directly into the gap.

It's computer vision doing your flossing. While you brush. Automatically.

Only Dyson would look at a toothbrush and think it needs a camera, a machine learning model, and a jet engine.

SpaceXAI 把一人公司 AI 员工写成操作手册了，收藏学习版！

我刚看完 SpaceXAI 新出的 Grok Bot Guides，这可能是目前最值得抄的一套 AI Agent 工作流。

重点是他们已经开始按公司组织架构使用 AI：

每个 Bot 都有独立岗位、长期记忆、自己的云电脑、工具权限、定时任务和技能，做完以后还能直接把任务交给下一个 Bot。

人不再需要夹在每两个 Agent 中间当消息转发器。

最夸张的一个案例，是一个人直接跑了一家 6 个 AI 员工的手游工作室：

一个负责统筹和上架
一个看投放和用户数据
一个做广告素材
一个写客户端和后端
一个管服务器部署
还有一个每天晚上扫 Sentry 修 Bug。

分析 Agent 发现问题以后，可以直接把结论交给创意 Agent 或工程 Agent，整条链路自己往下跑。

SpaceXAI 自己的 PM 玩得更狠：

Chief of Staff + 工程经理 + 5 个工程 Agent + 数据分析师 + 产品 Agent + 招聘 Agent，一共 10 个 Bot。

工程经理自己甚至不写代码，它的工作就是拆任务、分给 5 个工程 Agent，再检查结果——已经开始出现AI 管 AI了。

还有一套更像未来公司的玩法：

一个项目对应一个频道、一支 Bot 团队和一个 Notion 看板。

Manager Bot 自动创建项目、拉 Agent 进组、分配任务，卡住就把任务标成 Blocked，再来找人。

作者自己都发现，最后长出来的东西居然和人类公司的 Slack + Jira + 项目经理 + 专业团队越来越像。

这位仁兄对 Grok Bot 的讲解很具体，而且很有感染力，正因为如此，他的这份教程很受欢迎。

他分享的 11 个相关技巧很实用，值得收藏！🔖
