Just throw an agent at it, light work…
Security called me at 6:12 AM today. "Patch every PHP server immediately." I asked what happened. "Two critical vulnerabilities. Remote code execution. No authentication required." Cool. How many PHP servers do we have? According to inventory: 12 According to reality: Nobody knows. We found one running WordPress. Three running old internal tools. One under someone's desk. Two inside vendor appliances. A forgotten employee directory from 2016. And a server named: PHP-OLD-DO-NOT-TOUCH Naturally, that one runs payroll exports. Then we found a PHP 5.6 box. I asked who owned it. The documentation said: BRIAN. Brian left in 2019. We called Brian. He said: "Oh wow, that's still running?" Excellent. By 8 AM, leadership joined the incident call. CEO: "Can hackers actually get in?" Security: "Potentially yes." CEO: "Without a password?" Security: "Yes." CEO: "Then why do WE need passwords?" Not the lesson. Finance asked if we could wait until the weekend to patch because downtime affects revenue. Security explained that the alternative was letting strangers execute code on our servers. Finance asked for a cost comparison. At 9:17, someone suggested temporarily taking the vulnerable websites offline. Marketing refused. "Our campaign is live." So for the next hour, the company officially decided maintaining a landing page for 20% off webinar registration was more important than preventing remote server takeover. We finally patched everything we could find. Then our scanner discovered another PHP server. Hostname: TEMP-PHP-2014 Uptime: 4,512 days. Nobody knows what it does. Nobody owns it. Nobody can shut it down. But every time we block network access, the warehouse stops printing shipping labels. Security has classified it as critical infrastructure. It is running PHP 5.4. The vulnerability has existed longer than half our employees. The emergency patch took four hours. Finding out what PHP actually runs took eleven. The internet isn't held together with code. It's held together with servers everyone is afraid to turn off.

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
SpaceXAI and @cursor_ai are now working closely together to create the world’s best coding and knowledge work AI. The combination of Cursor’s leading product and distribution to expert software engineers with SpaceX’s million H100 equivalent Colossus training supercomputer will allow us to build the world’s most useful models. Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together.
