Elon Musk admitted he is not sure this one is possible. Musk: “This absorbs more of my mental energy than probably any other single thing. But it is so preposterously difficult that there are times where I wonder whether we can actually do this.” He does not talk like this. Mars gets a date. Robotaxis get a date. This gets a maybe. Stern: “What is so hard about it for just a normal person to understand?” His answer comes down to a single number. Musk: “In order to make a rocket fully reusable, you’ve got to basically create a rocket that can do about 4%, if not more than 4%, of its lift-off mass to orbit, which hasn’t happened before.” Four percent. Everything else standing on that pad is fuel, tank, and engine. The landing gear, the heat shield, the extra structure that survives reentry, all of it comes out of that same four. None of it can be left behind. The vehicle has to come home. Musk: “So that means you have to have basically A-pluses across the board: incredibly efficient engines, incredibly efficient structure.” Across the board is what makes this brutal. Most engineering lets you buy a weakness in one place with strength somewhere else. The margin here is thin enough that one component landing at merely excellent drops the whole vehicle below the line. Nothing carries anything. Musk: “But if full and rapid reusability can be achieved, it reduces the cost of access to orbit by a factor of 100 or more.” A hundred times cheaper turns nearly every question about space from whether into when. Telescopes, stations, factories, missions that never made it past a spreadsheet. Musk: “So we’ve got to get rockets to the point where we simply refuel the rocket and we don’t throw it away.” Every other vehicle humans build already works that way. Space is the one place we still build the machine, use it once, and let it fall into the ocean. Musk: “It’s the difference between humanity being a single-planet species and a multi-planet species. It’s really that big of a deal.” Now put his doubt in context. Landing an orbital booster upright was considered impossible by most of the industry. He spent years being told so while boosters exploded on barges. Those landings became routine, then boring, then unwatched. Then they stopped using legs. A twenty story booster came back from the edge of space, slowed itself, and hovered next to the tower it launched from. Two arms closed around it and took its weight in midair. Nothing touched the ground. That was a headline for about a day. He has been on this side of impossible before, more than once. Doubt from him measures how hard the thing is at the start rather than how it ends. Most people never attempt anything where failure is genuinely on the table. He found the hardest problem available and made it the center of his life. That is what real ambition looks like from the inside. Not certainty. A number nobody has ever hit, and showing up to it every morning until it falls.

BREAKING: Delta customers are now admitting that they’re booking flights with other airlines specifically for @Starlink Many Delta customers are complaining on 𝕏 and tagging the airline’s account, saying that Delta’s Wi-Fi is slow, unreliable, or sometimes doesn’t work at all.

France has recorded over 7,300 excess deaths during heatwaves this year, with a record 52 days of hot spells since mid-June, according to AFP. Separately, nearly 10,000 people across Germany have died so far this year due to heat-related causes, according to a German institute.

How is this legal lol

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.

These pamphlets from Britain are unbelievable. If you rape somebody, it will "affect" your asylum claim (not make it auto-fail), and you "could" lose your free housing and financial support from the government. You could!

Whenever you buy a new Windows laptop, one of the first things you should do is run Grok Build Windows and many laptop manufacturers ship PCs with a surprising amount of stuff you probably never asked for: • Trial antivirus and OEM apps • Preinstalled games and partner software • Ads, recommendations, news and widgets • Unnecessary startup/background apps • Temporary files and other clutter Instead of spending an hour digging through Windows settings and wondering what is safe to remove, let Grok Build audit the whole machine, figure out what is unnecessary and clean it up for you Just make sure it shows you the plan first and leaves drivers, security features and hardware-critical software alone Start with: “Audit this Windows PC and safely clean up everything unnecessary. Remove unwanted bloatware, trial software and preinstalled games, disable ads, recommendations, news/widgets and unnecessary startup/background apps, and clean temporary files. Do not touch drivers, Windows security, updates or anything required for the laptop’s hardware. Show me the plan first, then make the approved changes” A clean Windows install makes a brand-new laptop so much nicer to use

Grok 4.6 is now available on Amazon Bedrock. Thanks to @elonmusk and the @SpaceXAI team for the partnership. Looking forward to what customers build with this.

Grok Build just got a new update bringing a cleaner agent architecture, smoother prompt controls, a powerful new grok clone workflow, and major reliability improvements across sessions and tasks Release Notes: v1.0.6 Breaking Changes: • Subagent spawning no longer accepts capability_mode; tool access is now controlled only by agent type. Features: • Shift+arrow keys now extend text selections in the prompt like a standard text field. • Optional status line can now display live session info or script output at the bottom of the pager. • grok clone can now fetch a repo into a content store and mount a projected working tree. Bug Fixes: • Fixed session startup hangs on large or unhealthy git repositories. • Queued messages during goals no longer starve, and editing queued prompts works reliably. • Consent notice on first launch now shows clickable links and handles keyboard/mouse correctly. • Ctrl+C then edit a prompt now correctly removes the original text from the conversation. • Double-clicking a terminal command result now shows the complete output instead of a preview. • Consent notice links are now stricter and more reliable on all terminals. • Video generation now surfaces a clear ZDR error instead of raw API responses when output storage is required. • Project hooks on Windows now correctly expand $CLAUDE_PROJECT_DIR when invoking PowerShell scripts.
