Honored to announce that I’ve joined @spacexai! 🚀
I believe this team can do for intelligence what SpaceX did for rockets and the internet, I'm grateful and humbled to contribute to it.
If you have feedback on Grok, Grok Build, or the APIs; I'm all ears!
TIL while building an on-device HTTPS debugger:
Apple won't let individual devs ship any app that uses a VPN. Organizations only.
you can post anything on X 😭
here’s the list of western companies moving ai workloads to chinese models:
1. lindy → deepseek v4
2. cursor → kimi k2.5
3. coinbase → glm-5.2 + kimi 2.7
4. shopify → qwen
5. airbnb → qwen
6. uber eats → qwen2
7. siemens → deepseek + qwen
8. chapsvision → qwen
9. microsoft → testing deepseek v4
it’s becoming a procurement story!!!

You might believe you should spend less time thinking about code because of AI.
I strongly disagree! We’re watching this play out live where tons of AI generated code becomes a liability.
At the end of the day, an engineer needs to be responsible / on call for code that gets shipped to production. If you don’t understand the system you’re trying to debug, you’re probably going to have a bad time.
Yes, AI can help with all of this, if you set up the proper systems. You can have agents triage prod logs, look at errors, etc. You can speed up parts of the investigation, but an engineer needs to make the call. There might be serious customer or financial implications from that change.
I expect the trend continue for trimming dependencies, vendoring code so you can modify it directly, preferring simpler systems with fewer abstractions, and spending waaaay more time thinking about system design and code maintenance.
I’ve said this before, but it’s a great time to get familiar with CS fundamentals and some of the history behind what great software looks like. Many parts will be different in the coming years as AI progresses, but also a lot more than people realize will stay the same.

This is one of the smartest people in the world, without doubt. And I feel sad about how tunnel visioned the AI folks have become + on top of that they feel they have all the best ideas in the world because they are developing the things that's setting the economic agenda of the world.
But is this posture below even truly defensible? Have you never watched a scene in a movie and truly felt in awe of either the emotion it evoked or the spectacle that unfolded. Have you never wondered how the director came up with the "idea" of that scene? Because in their mind they had the whole thing before it even existed.
You think they express their ideas in mathematics and code?
You think people who paint, who produce music, who write stories have no ideas? Or you believe all of their ideas can be mathematically expressed?
How sad.

Midday is joining Ramp
We started Midday to build something we wanted for ourselves and it grew into something much bigger than we expected.
And here is the story behind it 🧵
