SpaceX has acquired xAI, forming one of the most ambitious, vertically integrated innovation engines on (and off) Earth → http://spacex.com/updates#xai-joins-spac……
SemiAnalysis CEO @dylan522p: There's a bet between the Heads of Compute at xAI and Anthropic over what percentage of worldwide datacenter capacity is in space by the end of 2028. “The bar is 1%. So, the xAI guy is really bullish." “I take the under on 1% by ’28, because that’s a gigawatt in space.” “But, it’s actually not that crazy. It’s roughly 150 Starship launches to get them to a gigawatt in space.”

Cursor 2.3 is starting to roll out! We’ve spent the past two weeks fixing bugs and making reliability improvements based on your feedback. I’m so proud of our team for sprinting to make this our best release yet. We’ll be rolling 2.3 out over the week to ensure there are no regressions during your holiday coding. I also wanted to shout out @theo, who had a rough experience with Cursor and was kind enough to stop by our office and give the team a ton of feedback on how we can make the product better (including helpful reproductions of issues from their team). There are a number of bugs in this release, specifically around worktrees and plan mode, that were fixed thanks to him. Thank you! There’s also been feedback on layouts and the default panes in Cursor across X and Reddit in the past week. We’ve been digging in and listening, and I hope you’ll love where we’ve landed. It’s always been slightly annoying if you’re using Cursor with 3+ different windows open for different repos. I was talking to @schickling about this last month, and we wanted a way to better hop between different workspaces. I still think there’s more we can do here, but I really like the new Command+Option+Tab switcher to move between layouts and workspaces (thank you @JasonBud!). Since I use Command+Tab on macOS all the time, this feels very familiar. Especially when defining custom layouts like in the video below to keep my terminal always open. We’d love your feedback as we keep working to make Cursor more extensible and customizable. Another small but nice thing: we heard your feedback that it's frustrating to have releases rolled out before the changelog is live, so we made sure the 2.3 changelog was posted before you saw the update button. Speaking of the update button, while it's great we're getting updates out frequently... I also agree it can be annoying to see the update banner every time you open Cursor. We've made it so this banner will show less frequently Happy holidays everyone!
Breaking News: SpaceX offered to buy shares from employees in a deal that would value it at around $800 billion as it prepares to go public.
Elon Musk’s SpaceX Valued at $800 Billion, as It Prepares to Go Public
Elon Musk on scaling AI in space: Earth is the bottleneck. "It’s harder to scale on the ground than it is to scale in space." "You’re going to get about five times the effectiveness of solar panels in space versus the ground, and you don’t need batteries. I almost wore my other shirt, which says, 'It’s always sunny in space.'" "In 36 months (but probably closer to 30 months), the most economically compelling place to put AI will be space." "Once you start thinking in terms of what percentage of the sun’s power are you harnessing, you realize you have to go to space." Source: @elonmusk with Stripe’s @collision and @dwarkesh_sp
With SpaceX's recent Mars-to-Moon pivot, @ashleevance says it's a "massive philosophical change" as Elon goes "all in" on AI: "The Mars thing was always part of Elon's genius because it sounded completely insane to most people, and yet it was part of building this religion that made you want to go to SpaceX and filled you with all this passion." "I feel like he's come back to Earth a little bit with this. I mean, you're still building a colony on the fricking moon, but it's slightly less aspirational. It's much more practical." "Clearly, the US government wants to beat China to the moon, although I don't think we will, but that's where the US government's attention and money is. With all the space data center stuff and this interplay between building these layers of infrastructure, I think he's chasing money and what makes sense in this near-term." "As someone who is his biographer, it's a massive philosophical change. I think Elon's really practical. I think he's all in on AI. He needs money to fund that. SpaceX is this sexy thing that people get excited about, and you can use it to raise money for other things." "I think it's the pressure and the immediacy of this AI race that might be making him make statements and decisions that normally he could put off."
BREAKING: SpaceX is in advanced talks to merge with xAI, per Bloomberg. The biggest IPO in history is coming very soon.

Adaption Labs CEO @sarahookr says data centers in space are "pretty bonkers", and explains what the current consensus gets wrong: "Most co-located hardware is pretty much for training. I think that's why you care [about Space], otherwise you can distribute. Inference compute, which is where everything's moving towards, you can spread that compute more easily. You can have multiple data centers [on Earth]." "So if you care about space, you probably only care about training compute. I think people underestimate the amount of failures that happen, and you don't want to get your training job interrupted." "The real issue is that GPUs still have failure rates. The 2% of GPUs that are just considered done every year, that's really your cost. It's how quickly you can replace those [in space] and what that looks like."
