Delta Airlines CEO Ed Bastian in new interview on Delta not adopting @Starlink: "We know what we’re doing in the space, and we’ve been the pioneer in Wi-Fi. We set that standard launching free, fast Wi-Fi that forced the industry to adopt it. We’re happy with where we sit." He said he wasn't worried about being at a competitive disadvantage by not having Starlink. Delta said it will adopt Amazon's LEO satellite internet, but won't start installations until 2028.

T-Mobile spent five years trying to get rid of the exact spectrum Elon just called "the last critical piece" of complete phone coverage in America. This 800 MHz block is Sprint's old Nextel spectrum, the stuff that powered push-to-talk walkie-talkie phones in 2004. The DOJ forced T-Mobile to divest it as a condition of the $26 billion Sprint merger. Dish had first rights at $3.59 billion and walked away because it couldn't raise the money. T-Mobile finally offloaded it to an investment firm called Grain Management last year for $2.9 billion plus a spectrum swap. Grain's original plan was selling it to utilities for private networks. Fourteen months later, SpaceX buys the whole portfolio, and shares of the carriers who passed on it fall as much as 8% in a single afternoon. Here's why it matters so much. Starlink's satellite signal at 2 GHz can reach your phone outdoors, but it dies at the first wall. 800 MHz penetrates buildings. Most phones already have the band built in. So satellites handle the open sky, this low-band layer handles indoors, and suddenly Starlink Mobile covers everywhere a normal carrier does without the tower network. Stack the moves. $17 billion for EchoStar's 50 MHz of 2 GHz spectrum. FCC approval for 15,000 Gen2 satellites this week. Now the low-band coverage layer. Verizon, AT&T, and T-Mobile paid $81 billion in a single auction for C-band spectrum in 2021, then spent years and tens of billions more deploying it on towers. SpaceX assembled a nationwide carrier out of a distressed-asset sale, a forced divestiture castoff, and rockets it already owns. The walkie-talkie spectrum from 2004 ended up being the piece that lets satellites replace cell towers. Nobody who touched it for twenty years saw that coming.

We announced an agreement to acquire a nationwide low-band spectrum license portfolio that will pave the way for @Starlink to become a major mobile carrier in the US. With this new spectrum and our Gen2 constellation, Starlink Mobile can ensure Americans have access to high-speed mobile broadband no matter where they are →

Excited to announce that all super intelligence organizations have now jointly agreed to the ultimate in AI/SI safety: Moving all testing to Delta Airlines flights, where accessing the Internet is utterly impossible!

i just automated our release and QA process! using Grok Bot i made two Team Bots: sandcastle, my release manager, and poteto, my engineer bot. i added them to Slack and made a new channel for managing releases. first i tell sandcastle that i want to do a cut. it'll DM all the contributors with links to their PRs so they know what goes in the next release and can DM the bot back if they have any blockers or objections. sandcastle then kicks off the build, watches it automatically, and starts up an automated fuzz swarm. usually this is 10+ agents running on Grok 4.7 xhigh to run the build, click around and use it like a real user (using our verification skills and feature map), some are directed while a few are "chaos monkey" clicking things randomly to see what breaks. whenever it finds an issue, i tell it to @ mention my engineer bot poteto, to spin up a Cursor Project to own triaging and fixing all the high pri issues. depending on the severity i may ask it to cherry pick the fix into our release branch and cut a patch release, or if it's a pre-existing issue i still fix it but include in the next release instead that's one more tedious task that Grok Bot now handles for our team

SECRETARY RUBIO: “Nationalism” became a dirty word. So we tore down our monuments, we condemned our own history, and in too many places we taught our children to be ashamed of the countries they would inherit. In the process we opened our borders, and outsourced our industry, and allowed our militaries to wither and to decay.

Grok Bot desktop 0.68.1 is out Bots can build slide decks with you now, 1:1 chats take on your Bot's color, and the Bot's computer got bigger and faster. New • Your messages in a 1:1 Bot chat take that Bot's color; set Accent to Black in Settings → General to turn it off. Requires Grok Bot 0.64.0 or later. • Bots can build slide decks with you, showing sample slides to choose from, and deliver them as PowerPoint files or Google Slides. • Bots can send formatted emails from a draft card, so recipients see headings, bold text, and lists. • Bots can search your Gmail Spam folder and move a message back to your inbox. • Team Bots can mention a Slack user group so its members get notified, while @​here and @​channel still don't ping anyone. (Teams) Improved • Typing / in the composer no longer opens a menu of skills and actions. • Bots work faster on their computer: actions settle sooner, screenshots come back quicker, and new windows skip a five-second wait. • The Bot's computer has a 1920 × 1200 screen, up from 1280 × 800, giving more room when you watch it or take over. • In Slack threads it follows, a Team Bot stays quiet on untagged replies that don't need it, such as emoji-only replies. (Teams) Fixed • Gmail actions fail less often: send and reply no longer report a missing tool, and Bots wait out Google's rate limits. • Email drafts show up as a card in the chat, a Send cut off by Stop still goes out, and attachments keep their file names. • The Bot's browser recovers from a crashed tab, handles large uploads, and gives up on a stuck page after 25 seconds. • Stop or a new message ends a Bot that's stuck on an unresponsive step within about 30 seconds. • Secure Forms fill into the page the Bot has open, and checkout card fields get a Secure Form instead of a screen handoff. • When X or Vercel needs you to sign in again, the Bot shows a reconnect card instead of retrying or giving up. • If the app's window crashes, Grok Bot reloads it instead of leaving it blank. On Linux and Mac (Apple silicon) now. Notes:
