On the rise of transgenderism with @GadSaad:
“When I’m a Hollywood superstar, as you said earlier—the stats on having one transgender child are already abysmally low. Having two, three, or four is nonexistent. So it becomes a pathway for me to demonstrate that I’m deserving of empathy.
“It’s a form of Munchausen.
“Munchausen syndrome by proxy is when I cause injury to someone I care for—my biological child, my pet, my elderly parents—because I’m going to get empathy and sympathy by proxy through harming them. ‘Look, I’ve got an ailing child.’
“So the transgender parent you see with the Hollywood star is engaging in Munchausen by proxy.”

New episode of @SpaceX documentary
A fully and rapidly reusable rocket will fundamentally change how humanity accesses outer space. “The Holy Grail of Rocketry” continues the ongoing Starship series with a look back at the scrappy days of SpaceX engineers proving reuse was possible and takes you onboard a high-seas race to recover a floating Starship

Only Grok is the most neutral AI....literally
And this has been consistent across different neutrality and political-bias tests
Grok stays grounded in reality and answers as truthfully as possible
An AI you can trust to give you reality.....not drenched in woke garbage

BREAKING: SpaceX’s Starlink satellites performed 207,152 proactive collision-avoidance maneuvers in just six months.
The advanced autonomous system:
• Detects potential close approaches
• Calculates the level of risk
• Adjusts orbital paths when needed
• Acts at a highly cautious threshold of just 3 in 10 million
SpaceX is managing the world’s largest satellite constellation with precision, automation and a safety-first approach.

I had @bot go through my emails and unsubscribe from recurring payments, TV streaming, and media.
It works by getting to the cancel screens, then choosing to stay subscribed at a lower rate.
In one day it has saved me $1,600/year.

True
Great conversation with @chamath, @jason, @davidsacks, and @friedberg on all the work ahead when it comes to diffusing benefits of AI broadly, earning permission from communities, and ensuring AI safety and control.

Grok Build
Grok Build just got a pretty substantial upgrade across MCP, memory, long-running sessions, and overall agent reliability
MCP tools can now return structured JSON, cancelled tool calls actually tell the server to stop working, memory can be managed directly from the /memory browser, and long-running sessions keep their compaction checkpoints instead of losing them during cleanup
There are also fixes for macOS image pasting, subagent cancellation states, /rewind, huge skill files flooding context, Windows cloning, and minimal-mode session handling
A lot of edge cases cleaned up here...especially for people running heavy agent workflows for long periods
Release Notes: v1.0.33
Features:
• MCP tool results now include structured JSON data when the server provides it.
• GROK_GROVE=1 now enables both clone and worktree features when specific knobs are unset; missing remote settings no longer force copy.
• Delete memories from the /memory modal using two-press x; only actual notes (not generated indexes) can be removed.
• Composer footer now shows the Alt+Enter chord for inserting a newline when Cmd+Enter is unavailable over SSH.
• /memory now always opens the memory browser modal; status and toggle are available via keys inside the modal instead of command arguments.
Bug Fixes:
• Fixed a bug where pasting an image on macOS could attach the wrong image.
• MCP tool calls listed directly now show their name, arguments, and any error message.
• Background subagent tasks now correctly show cancelled status when the parent session closes.
• The Subagents dock no longer shows an unclickable "Done N completed" row after all subagents finish.
• Cancelled or timed-out MCP tool calls now notify the server so it can stop work instead of continuing in the background.
• /rewind no longer fails when older compaction checkpoints are missing after a session sweep; only the base checkpoint for the target matters.
• Large skill files are now capped at the same 25k-token limit as other reads; oversized skill bodies show a truncation note instead of flooding context.
• Long-running sessions no longer lose old compaction checkpoints or prompt offloads during the 30-day cleanup sweep.
• Auto "where was I" recaps no longer appear while a scheduled task, monitor, or workflow is still running.
• In minimal mode, confirming /delete or /exit now immediately opens a new empty session instead of appearing stuck.
• In minimal mode, resuming a session after /new now correctly reloads its history instead of showing the wrong session.
• MCP tools that take no arguments no longer show a stray "{}" line in the permission sheet.
• Fixed Windows clone and attach failures when .git/config values contain backslashes, quotes, or other characters that must be escaped.
• /memory modal now shows clear explanations when memory is disabled and helpful empty states instead of blank panes.
• /memory (and on/off toggles) no longer leaves user bubbles or host turns in scrollback when opening or changing the modal.
• Fixed Windows clone staging directories that could not be cleaned up after deadline or cancel during shallow bootstrap.

Elon just gave one of the clearest explanations yet for why Terafab has to exist
There are basically two problems:
• Geopolitical risk — at some point, advanced chips from Taiwan may not be available
• Scale — even if supply remains stable, existing fabs eventually run out of capacity as AI, humanoid robots and autonomous cars keep scaling
And chips are the foundation underneath all of it
Server AI, edge compute, Optimus, Tesla vehicles....everything needs enormous and reliable semiconductor supply
Elon:
“So it’s either build Terafab or fail to scale”
That pretty much sums up the entire strategy
Secure the chip supply....then scale AI and robotics without a ceiling

SpaceXAI engineer Lingxi Li, @lingxi, runs code cleanup while everyone else is asleep. Nobody is shipping at 3 AM, so conflicts are rare and the changes are low risk.
His bots start a research agent that sweeps the monorepo for quality issues, poor modularization, comment bloat and security gaps. He wakes up to a stack of PRs.
Three SpaceXAI employees are building a company in 3 days with Grok Bot. This is Day 1.
Matt Palmer (@mattyp), Lauren Tan (@poteto), and Roshan Sadanani (@roshan_s) start with research, a plan, and a product.
Live now, plus sessions for engineering, product, and founders.

Finally!!! A proper orbital attempt! Important note is that they won't be targeting orbit at SECO. They will only attempt an orbital circularization burn if all systems are go and it's considered safe. Nice and conservative approach!
Starship is preparing to go to orbit. Flight 14 is targeting to launch as early as Tuesday, September 22, pending regulatory approval → spacex.com/launches/starship…
