I asked Grok @bot to explain rank, spectral power, and optimization in geometrical terms, and compare them with Adams, Muons, and Aurora. Below is the result. If you have any suggestions on how to make this video better and more intuitive, please comment below. My Grok @bot will pick them up and incorporate your ideas.

Some ways people used Grok Bot this week:

Starship completed a single engine static fire demonstrating a deorbit burn for upcoming orbital missions

Did you know the ambulance went to the wrong address? Did you know the Medical Ventilator the EMT’s hooked George Floyd up to was not plugged in? None of these details were allowed in Derek Chauvin’s trial.. I remember when I saw all of the footage at the time, something seemed very off and staged about the entire thing.

𝕏.com continues to surge, growing faster than Google, YouTube, Facebook, Instagram, and Reddit last month. 🔥🚀

Grok 4.6 just tied for #1 on the Artificial Analysis Agentic Index • Grok 4.6 (high) — 59 • Claude Opus 5 (max) — 59 Outperforming Claude Fable 5 and GPT-5.6 Sol We’re entering the agentic era, and this is exactly the kind of benchmark that matters so much: tool use, planning, autonomy and complex problem solving Grok 4.6 is now sitting at the very top And that matters even more as Grok powers Grok Build and Grok Bot, where the model has to go beyond answering questions and actually take actions, use tools and complete real work Grok’s agentic capabilities are getting seriously powerful

.@bot is just so damn good. I've got multiple Google Workspace accounts that are authenticated and being used. It just works. Also works perfectly across both my Mac and my iPhone. I have two bots right now: 1. Chief of Staff - "R2" knows everything about me and runs my calendars, email, tasks 2. CRM - "Lando" Runs my outbound sales funnel and coordinates with R2.

Goodbye mental load....hellooooo @bot ! I know, I know. Grok Bot seems like it must be the next new thing for tech bros cold plunging in Patagonia vests, but hear me out moms (yes moms because disproportionately, the mental load falls more on moms than dads). Offload that mental load to AI and watch things just get done. Is it perfect? No. Is it amazing? Absolutely. Grok Bot is the new AI assistant from the team at Cursor + SpaceX (they're calling it SpaceXai). It's surprisingly useful and easy for non-technical people to use, and it can do a whole heck of a lot more than Claude and ChatGPT with little to no setup. Here are actual things that Grok Bot did for me this week (almost completely independently): - Looked through back to school emails and made sure I was prepared with everything that needed to be done for multiple kids. Mental load unlock: 100% I would've forgotten to pack a space change of clothes for my kindergartner on her first day. - Found 3 gift cards I somehow forgot to use from the last year. Oh right, I DID buy 2 Gap gift cards from Costco on black friday! Duh. Mental load unlock: Cha-ching! That's $150 in my pocket. - Scheduled multiple appointments for me. I've been putting off my annual physical exam because who has time to call the doctor. Grok Bot looked up options, pinged me with 3 dates/times, then booked it (I just had to confirm Zocdoc on the last step). It created a calendar reminder! Mental load unlock: Moms, we often put off our own health/wellbeing. Finally! AI can help. I also had it schedule a hair appt and massage for later this month. Let's go AI! - Listed a Facebook Marketplace item and is managing the sale. I had purchased a wagon for my kids years ago that's been collecting dust. Grok Bot found the old listing, used the photos, and asked me what $$ I want to list at. It's going to manage the rest (wish me luck here). Mental load unlock: Who has time to sell their old crap? I sure don't. But AI has infinite time. Notice, none of these are work examples. I will do those in a separate thread. All of these things are being done in the background, and I'm only being asked to approve or provide the AI direction. Don't be intimidated! Literally, if you've used WhatsApp or iMessage you can use Grok Bot with NO TRAINING. AMA I'm blown away by this tech. Photo is of my home assistant (her name is Helen) independently ordering my kindergartner a photo from Walgreens that mama somehow forgot about. Oops.

WTF, GROK BOT JUST MADE AI AGENTS AVAILABLE TO LITERALLY ANYONE – CREATING CONTENT HAS NEVER BEEN THIS EASY, EVEN IF YOU'VE NEVER MADE ANYTHING BEFORE Content was never a talent problem. It's a headcount problem. One person doing research, design, copy, analytics, timing and publishing – that's six jobs. The switching between them is what kills consistency, not a lack of ideas. Here's what one of these setups actually looks like. A Chief of Staff sits in the middle and routes every task. Nothing lands on the human. → Researcher tracks what's actually moving and pulls real sources instead of guesswork → Writer turns that research into finished copy, ready to review → Visualiser gets fed a few reference visuals once, then ships everything in that style → Analyst reads the numbers and tells the rest of the team what worked → Scheduler owns timing and holds the queue → Publisher ships it The part that makes it work: every agent on Grok Bot gets its own persistent computer, browser and file system – and they all share memory. So the research is already sitting inside the draft before the draft starts. No copy-pasting between tools. No approving every step. No human in the middle. You can even teach an agent a repetitive task by recording yourself doing it once. Start recording, do the thing, stop. It learns the pattern. And that's the real shift. Nobody needs AI to tell them what to post. They need it to delete the 40 steps between the idea and the post. Everyone has a backlog of things they've meant to make for months. This is what starts clearing it. Full breakdown of the setup in the article below ↓

Last week I posted a new paper with Patrick Norrick: “Terra Incognita: The Economics of a Shrinking World.” We chose the title deliberately. No society in history has experienced the fertility levels now seen in South Korea, China, Thailand, Colombia, Chile, and many other countries. Our knowledge of the causes (and of the economic consequences) remains far more limited than most public discussion acknowledges. Much of what we write is, at best, educated conjecture. The paper also struggles against a space limit. We wrote 20,000 words, far from the 250,000 or so we would need to address some issues in more detail (if I had the time and resources to hide away for a year, I could do that, but not now). That means some ideas are only sketched. Nonetheless, we emphasize several important points. First, fertility has fallen very fast everywhere: rich and poor countries, east and west, north and south, conservative and liberal societies, religious and non-religious societies (with the exception of the Jewish population of Israel; fertility has also collapsed among the Muslim population within the pre-1967 borders), you name it. Even in sub-Saharan Africa we see fast and unprecedented drops in fertility (alas, from a high initial level). Second, and this is really interesting, the fertility collapse has been concentrated in poor and lower-middle-income countries much more than in rich countries. By now, income per capita and fertility are positively correlated within OECD countries. We conjecture this will hold globally in a few decades. Third, and related to the second point, the fertility collapse has been concentrated among poor and lower-middle-income women within countries. In countries such as the U.S., the rich and highly educated now have more children than the poor and less educated. Fourth, we document why we do not understand the data from the U.N. World Population Prospects. See, for example, Tables A.1 and A.2. Fifth, we explain why some proposed mechanisms struggle when confronted with the data. A more subtle point is at work here. Many commentators do not seem to understand the difference between proximate causes and ultimate causes. Yes, births might have gone down because fewer women are in long-run relationships. That is the proximate cause. But you need to explain why fewer women are in long-run relationships (the ultimate cause), and saying that they spend more years in school, to take one example, does not get us very far. Why do they spend more years in school? Once you start down the whole chain of reasoning, things become much harder than they seem. The paper can be found here: sas.upenn.edu/~jesusfv/Demog… Comments always welcome!

Derek Chauvin was unjustly convicted of murder, therefore he should be freed. The facts show that he was not the cause of death, nor did he at any time intend for a death to occur. Whatever else he may be, he is not a murderer. That is the truth.

My Grok Bot just paid its own salary. Which is completely insane. I gave it one job... Win back churned customers. It: → Found everyone who left in the last 6 months → Emailed them → Won several back → Collected their feedback Then overnight... → Analysed why they left → Built a 5-step plan to improve the community It has already covered its cost. This is getting ridiculous.

WE ARE NOT THE SAME! SAVAGE BASTARDS 🤬
