life cycle of a tweet you know a post is doing well when you start getting the shut up u retard replies

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 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.

Matt Palmer (@mattyp), Lauren Tan (@poteto), and Roshan Sadanani (@roshan_s) start with research, a plan, and a product.

The p(doom) discussion gets all the headlines, but the p(abundance) scenery is far more like and deserves much more engagement.

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…

It would be great to build a Grok Bot that does exactly this: figures out the biggest constraint in your business and pings you every week so you know what to focus on.

Probably nothing

Five years ago today we lost a legend.

Starlink V3 constellation starts being deployed this month. Ultimately, it will deliver more than 100 times the bandwidth of our current 11,000 satellite constellation.
