Yep you're right in current time but ignore the future: "This is classic Musk playbook—big vision + hype to drive valuation—but the underlying physics and Starship cost reductions make orbital compute a genuine long-term bet, not pure vaporware.Overall verdict: The post is largely correct and well-researched. The 100 kg radiator per 1 kg GPU claim tracks with 2026 technical analyses scaling real ISS hardware. Costs are a massive hurdle for orbital datacenters today (radiator mass is the "economic knife edge"), and Earth-based options with micro reactors look cheaper in the near term. The IPO-timing critique is fair given the announcement schedule. Nuance: Optimists (including some SpaceX-aligned analyses) argue Starship + hotter chips + deployable radiators could close the gap over time. But as of mid-2026, the post's skepticism on economics holds up well. No major factual errors."

I can't believe how many people are there that think this You add giant panels to radiate the heat out with high-emissivity coatings, pointed at deep space You have a lot of space in space to do this!

@levelsio We need datacenters in space, but I'm still waiting on a good explanation of how the heat is exhausted Heat can only be expelled via radiation in space, convection and conduction don't work in a vacuum. (ME potential, but not a long-term solution) Please link me to a good

Okay I tried the same Null Modem with 👹 DOOM and it works too, it's super laggy though I think because the BAUD rate is 14400 (like 14.4kbps or 1.8 kilobyte per second!) DOOM was the first game that made multiplayer game networking mainstream and it literally invented the word "deathmatch" But it works, very cool pieter.com/assets/dosbox/…

Okay I spun it off as a Quake 1 web-based multiplayer game + server you can play now at: 👉 q1.pieter.com 👈 It still works via null modem and you get instantly paired to another player (if there is somebody) and it's just a 16mb download of Quake 1 demo instead of

Next thing people are saying you can't do inference or training because satellite to satellite latency is too big Also mostly wrong: x.com/i/grok/share/3…

There is quite some latency because every package goes through my server and Quake 1 did not have client-side prediction yet (which is what Quake World added later), I'l try get QW running to see if it improves it a bit Group multiplayer can come but for that I need to see if I can get actual COM1 modem connection working not just a null modem! Here I'm playing a local LAN death match with @javilopen on a game from 1996 in a web browser via a COM1 serial port tunneled via Websockets over the internet! 🤓

🔌Today I created a virtual web-based null modem so now you can finally play Quake 1 (from 1996) in multiplayer in the browser with other people online! This week I was able to create a virtual printer that listens on the COM2 port to make a web-based printer work in Windows

🔌Today I created a virtual web-based null modem so now you can finally play Quake 1 (from 1996) in multiplayer in the browser with other people online! This week I was able to create a virtual printer that listens on the COM2 port to make a web-based printer work in Windows 3.11, like on you can actually print to, it was one of my ideas when I started pieter.com but it was always too difficult to make, I had no idea where to start, but this week AI was able to do it! Today I woke up and thought "if we can listen to COM2 via JS, how about listen to COM1 from Quake 1?" then we could forward the COM1 data via Websockets and to another user to create a virtual null modem (A null modem was a cable you'd use to connect two computers to each other directly in the 90s, if you couldn't afford buying a network card you'd use this to network, but you could only play with one other computer not multiple) So I built it, it took about an hour and works! I wanted to get Quake 1 in DOS to work with multiplayer for 2 years but I could never get it to work, but now it did it This project is a good benchmark of how capable AI is becoming, figuring stuff out that humans would take months within an hour You can try it here, I don't know how it will match lots of people but let's see, you have to exit to DOS first (ALT-F4 or FN-Option-F4 on Mac), then type CD games, then CD quake, then quake, then ESC, then Multiplayer, then either Create New Game or Join Game, and use Direct Connect, keep settings same and you're in! pieter.com/assets/dosbox/…

🖨️ Next in the printing saga: I installed Print Shop Deluxe 2.0 from 1994 It lets you print these giant banners, I vaguely remember doing this too And it works with our web-based matrix printer! You can try it on pieter.com, make sure you select the vertical ones,
