Does anyone else want a monitor stand that's just a chunk of rock?

Jensen Huang: "If that $500,000 engineer did not consume at least $250,000 worth of tokens, I am going to be deeply alarmed. This is no different than a chip designer who says 'I'm just going to use paper and pencil. I don't think I'm going to need any CAD tools.'"

@elonmusk @HarmlessYardDog Good times create low input high risk supply chains.

Which one of you bozos thought it was a good idea to build the entire world economy off just in time supply chains from the most unstable regions on the planet?

Mass is the key constraint in doing anything at scale in space. We can launch more from Earth, but sooner or later we need to use the materials already out there…

The secret plan is out! Two great articles today about our plan to capture a small asteroid and bring it into Earth orbit. The concept is part of our New Moon mission, which explores relocating a small near-Earth asteroid into a controlled orbit as the first step toward building industrial infrastructure in space. Our team has been developing the key technologies for this approach for years, including capture mechanisms to constrain and move small asteroids and orbital debris. Accessing materials already in space could eventually enable a new generation of industries beyond Earth. If you're interested in the future of space resources, these articles are worth a read. hashtag#space hashtag#asteroidmining hashtag#spacetechnology hashtag#spacex hashtag#venture

IMAGINE THE MOON 🌖
🔊 Sound On 🔊
With Elon and @SpaceX making waves toward a lunar landing, we asked Grok to outline 9 Steps To The Moon, including key challenges and proposed solutions.
STEP 1: Reliable Transportation
Launch constraints & reusability: Achieving frequent, cost-effective trips to the Moon without reliable heavy-lift rockets risks stranding missions.
Finalize Starship orbital refueling and rapid reuse; conduct 50+ test launches from Earth to build a fleet capable of 10-day turnaround cycles. Integrate AI for autonomous operations.
STEP 2: Precise Lunar Landings
Surface access & stability: Moon's uneven terrain, low gravity, and dust plumes make safe, repeated landings a core risk for crew and cargo.
Deploy uncrewed Starship landers for site surveys; test precision guidance with LIDAR and AI; establish initial landing pads using regolith sintering.
STEP 3: Radiation Shielding
Exposure to cosmic rays & solar flares: Without Earth's protections, radiation could cause cancer or acute sickness in long-term habitants.
Design habitats with water-filled walls or buried under regolith; test inflatable modules and active shielding (e.g., magnetic fields). Use robotics for initial construction.
STEP 4: Thermal Management
Extreme temperature swings: From +120°C days to -180°C nights, this fries electronics and threatens life support.
Develop multi-layer insulation, heat pumps, and nuclear/solar hybrid systems; network data nodes for real-time monitoring across base zones.
STEP 5: Dust Mitigation
Abrasive lunar regolith: It clings, erodes seals/suits, and poses respiratory hazards, making sustained ops unviable.
Engineer electrostatic dust-repellent coatings, airlocks with plasma cleaners, and paved surfaces; create domes as sealed habitats mirroring our model.
STEP 6: Power Generation
Energy in long day/night cycles: Solar alone fails during 14-day nights; unreliable power halts all systems.
Deploy foldable solar arrays with battery storage; integrate small nuclear reactors (e.g., Kilopower); fold zones for distributed grids.
STEP 7: In-Situ Resource Utilization (ISRU)
Dependency on Earth supplies: Without extracting local water/oxygen/metals, costs skyrocket and self-growth stalls.
Mine polar ice for H2O/O2; 3D-print structures from regolith; gate realms for resource processing plants.
STEP 8: Closed-Loop Life Support
Sustaining air, water, food: Open systems require constant resupply; failures mean mission end.
Host cloud-like bioreactors for recycling (e.g., algae farms); violet-hued hydroponics for food; AI-optimized for 6+ crew.
STEP 9: Self-Growing Infrastructure
Scalability & autonomy: Manual builds limit expansion; need auto-replication for a true city.
Use AI robots for additive manufacturing; launch mass drivers for exports; encode waves of data for orbital integration (e.g., Starlink hubs).
How did Grok do @elonmusk ??? 🚀

Dopamine Per Scroll
I asked @grok a few months ago to envision a dopamine per scroll equation for fun. Eternally glad this is not the core objective of X, it is why I trust this platform and team over any others.
Dopamine per scroll ≈ B × P(R) × I × S
Where:
- B = Baseline phasic transient size for low-stakes anticipation/novelty (rough estimate: 0.05–0.2 μM peak in ventral striatum for mild cues; far below food/sex ~1–5 μM or drugs 10+ μM).
- P(R) = Probability of a rewarding outcome on that scroll (the "hit rate").
- ~5–20% of scrolls might deliver something engaging (funny post, like on your reply, viral thread, mutual follow notification, etc.).
- Average P(R) ≈ 0.10 (10%) is a plausible guess for moderately active feeds; addictive feeds push it higher via algorithm.
- I = Intensity / salience multiplier of the reward (0–10 scale, subjective):
- Neutral new post: ~1
- Mildly interesting: ~2–3
- "Damn that's good" or small notification: ~4–6
- Big validation (viral reply, blue-check interaction): 8+
- Average per rewarding scroll ~3–4.
- S = Sensitization / tolerance factor (≥1 when fresh, <1 when tolerant/burnt out). Heavy users may have S ≈ 0.4–0.7 due to downregulated receptors.
Calculation in relative "dopamine units" or rough nanomolar scale:
- Average scroll: mostly nothing → very small anticipatory bump (~0.02–0.05 units from mere novelty/expectation).
- Rewarding scroll (10% chance): 0.1–0.4 units peak phasic burst.
- Effective average per scroll: ~0.03–0.08 "units" (tiny but compounds over hundreds of scrolls).
Per hour of scrolling (200–400 scrolls):
Cumulative ~6–32 units

@DevinSoto @X Interesting angles.
Of course, there is a “but” here: dopamine spikes are not the purpose of this company. Humanity is, as far as I know.
English
As a user, it's simple. I open the @X app. Here's what I hope to see — and I suspect many of you do too:
1. Great, informative, useful, or entertaining content (by humans, machines, or companies)
2. Real, authentic — even “boring” — posts from the people and networks I actually care about
3. No spam, bad bots, or reply farming
As an X employee who uses it every day, I believe we’re actively building toward exactly this.
Does this match what you want when you open X?

@Storm_TS2C_M @elonmusk @SpaceX @grok Totally me too. Have to send him on some galactic voyages and repost. 💯

Physicists: "The greatest issue of our time is that physics is fundamentally incomplete, that we have no firm footing from which to explain our best theories"
Also Physicists: "That's completely impossible, the laws of physics forbid it."
