Last night while I was heading to bed, this very thought also crossed my mind... kind of sucks 😮‍💨
Perhaps the threat was never a rogue AI agent trying to subvert humans—but humans using AI to hurt other humans.

Dynamic dashboards and live dynamic docs, straight out of the box 😬
Grok Bot can now build reports, memos, and dashboards. Ask Bot for a page, then edit it together or have Bot keep it up to date.

AI slop in internal docs and Slack channels is getting out of hand. Don't be a meat proxy. Really, stop it!

Managing scale at this level is insane 🤯 ​Anthropic just dropped a breakdown on why and how they built their own in-house source control system to handle thousands of daily merges. ​A must-read for backend & infra engineers 👇
New on our Engineering blog: Creating in-house source control. In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale. Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: anthropic.com/engineering/re…

I've been thinking about this kind of structure for a while now. Glad to see I'm not crazy!

The agents are the easy part. What makes this work is one person owning the problem end to end, without handoffs to product, QA or another team in between. Most orgs will struggle with that part, not with the tooling.

Important note regarding Grok @Bot: Going forward, @SpaceX will use the best back end model for any given task, including Claude Opus 5.5, MidJourney, Suno and other leading APIs. Whatever is most likely to give you the best outcome.

Honestly I strongly believe that this is the future of Engineering. Verification skills verifications is the next frontier. Kudos to the Team.

Don't spoil the canonical rite of passage! Some of us have to learn the hard way. 😅 ​Can confirm though, that latency cliff is real.
serverless databases are a scam. this is a graph of us going from serverless to provisioned capacity on one of our databases.
