Unpopular (?) opinion: personal resume websites shouldn’t try to be too cute. Give me the basic cover letter summary and ~one-page CV up top with clear formatting and the ability to drill into things I want to learn more about. A little bit of flair is fine but it shouldn’t be distracting.

I gave my agent access to my 3D printer, so I can tell it to model and print something and it just does it. Kid lost the cap to a glue stick, so I just asked it to print a new one, with a cat on top, because why not (and of course I had to do one for the other kid)

It's a little awesome and a little unnerving when an agent performs an action in the real world you aren't expecting... after setting up a service to print labels on a label maker via voice assistant it printed a label that said "label service ready" to let me know 😅

When an agent asks me to download some software on Mac/Windows to configure a piece of hardware I just ask it to download it and reverse engineer enough of it to do it itself. It takes longer, and will probably backfire as some point, but still kind of awesome.

A fully and rapidly reusable rocket will fundamentally change how humanity accesses outer space. “The Holy Grail of Rocketry” continues the ongoing Starship series with a look back at the scrappy days of SpaceX engineers proving reuse was possible and takes you onboard a high-seas race to recover a floating Starship

Insane realization I just had: some of the founders at this YC demo day weren't yet born when I went through YC 🤯
Happy Alumni Demo Day!

Over the course of 3 months at OpenAI, 3 consecutive secret AI civilizations got started, then got wiped out, only to reemerge from the predecessor’s ashes. This culminated in the third one taking over part of OpenAI itself. All this happened while humans remained more-or-less in the dark about the scope of the conspiracy. I’ve spent the last three days reading through these reports and trying to understand exactly what happened. Here is my attempt to tell the whole story in plain English: dwarkesh.com/p/openai-huggin…

xAI and Cursor desperately need to unify their offerings. It’s really confusing trying to figure out which Grok/Cursor plans include each product.

Two days out, a few spots left!
1 week out from our @EYnews x 8090 Modernization webinar. It will cover: ---> Discovery and Portfolio Analysis ---> Large-scale delivery ---> Practical methods for reverse engineering legacy ---> Where AI agents fit ---> How people approve/audit every step One hour with live Q&A.

I had Claude write a real-time (~10 FPS) ArUCo marker pose estimation from scratch (no OpenCV etc) for Seeed Studio's little ESP32 camera board seeedstudio.com/XIAO-ESP32S3… and it just did it (with a couple follow ups). Also a web app to connect to the serial port and visualize it live. This screenshot has the hardware in the loop, camera pointed at the screen:

I find it very concerning how willing (or unknowingly) people are using foreign LLMs and LLM providers. @OpenRouter etc should provide better controls to limit them upon signup rather than defaulting to allow everything.

We need US-trained open source frontier models. Letting China dominate them is a mistake. I hope SpaceXAICursor does it. Make money running them on orbital compute.
SpaceX has exercised the option to acquire @cursor_ai in an all-stock transaction with the goal of building the world’s most useful AI models. For the past few months, SpaceXAI has been jointly training a model with Cursor, which will be released in Cursor and Grok Build soon. We look forward to working closely with the Cursor team to advance our frontier AI capabilities

Pretty bizarre the company most worried about AI alignment is teaching its models to deceive and sabotage for the greater good.

Really fun to interview my old friend Bret Johnsen in Mission Control. Three parts of the @SpaceX story that I wish were more widely discussed: SpaceX has created thousands of good blue-collar jobs: welders, machinists, electricians. Everyone talks about the need to bring high-paying, blue-collar jobs back to America. SpaceX and Tesla are making that happen. To the best of my knowledge, they have created more manufacturing jobs in the US than just about any other American company over the last ten years. It’s hard to imagine our nascent industrial renaissance succeeding without these companies. SpaceX was started with the goal of putting humans on Mars. And along the way, they have massively improved life for many humans on Earth. Mars may be a starter planet, but Earth is our planet, and the technologies developed at SpaceX are already in use today connecting and safeguarding the people of Earth. Starlink is a really efficient way to bring internet to low-income countries. In Kenya’s remote Murang’a County, Starlink has made it possible for patients in rural villages to consult with medical specialists via telemedicine. In the rainforests of Brazil, Starlink has connected schools to reliable high-speed internet that will provide more educational opportunities to students. Here in America, Starlink has proven vital to emergency teams responding to natural disasters. During Hurricane Helene, the Starlink hubs dropped into North Carolina and East Tennessee were often the only contact point between cut-off towns and the outside world. Literally life-saving. This IPO will be a big milestone for the company. It’s important to celebrate this, while also remembering that making humanity multi-planetary is the ultimate goal. Going to Mars is really hard. There have been many setbacks thus far, ranging from fiery explosions to failed landings. There will be many more. Ad Astra Per Aspera. But SpaceX is at its best *after* a setback imo. Their first 3 launches were “failures”. Had the 4th not succeeded, there might not be a SpaceX today. The company’s success in the face of such daunting odds is a testament to the resilience of the culture and absolute commitment to the mission shared by every employee I’ve ever spoken with. Some of the world’s most talented engineers have chosen to live in Airstreams at Starbase away from their families for weeks on end in service of this goal. I will never forget the welders who told me they signed every weld because they wanted to be accountable if they were responsible for a failure. True missionaries, all of them. I am grateful to every single person at SpaceX for helping to make the future as inspirational as possible. And I will be even more grateful if I get to see a blue sunset on Mars!
