Many users dismissed Elon Musk's prediction that space will become the cheapest site for AI compute within 36 months as impractical, goofy, and vulnerable to attacks.

@elonmusk The number of computer chips will outnumber the energy supply.

The future currency is wattage

@elonmusk “How bad is the US bureaucracy?” “The US bureaucracy is so bad that it’s cheaper and faster to build rockets to launch datacenters into space than it is to try and build a datacenter in the US”.

@elonmusk According to the Grok, we (U.S.A.) consume about 11 TWh per day, not 0.5 TWh per day stated in the interview.

Space GPUs will be the apex of technocapital. There's no weather in space. No water, no air, no night, no seasons. There are no permits in space. No NIMBYs, no decels, no life. Just energy flowing through your capex. Pure cookie clicker loop from here to heat death.

@elonmusk I put this together for anyone curious about data centers in space. Just a quick rundown of the biggest pros, cons, and hurdles I could think of.

@elonmusk It will be a great Idea to put AI centres in space!! I'm sure they are not gonna require water in space!

@elonmusk Using these autogenerated captions when Dwarkesh has a meticulously accurate transcription on his site is a shame

If data centres were built near Hospitals and other public buildings The heat could be used for heating hot water via heat exchanger technology and even for central heating any additional cooling on return flow to the data centre could be either free cooling in winter or chiller this energy saving would be huge

@elonmusk Why 30 months? China can build a hospital in days... A proof of concept StarCompute unit shouldn't take anywhere near that amount of time, imo.

Is Elon time starting to skew as you get older or something? 😂

@elonmusk @elonmusk I understand the concept but you say you wouldn’t need glass 💭 how would you protect it from impact of meteors showers and debris in space? Look at all the impact zones on the moon. Or did I miss something in concept?

@elonmusk “So if you look at electrical output, everywhere outside of China, it’s more or less flat.” — Elon Musk While China is surging ahead, the rest of the world has been basically flat for years. Energy is the real bottleneck for AI and the future. ⚡ #ElonMusk #Energy #AI #Future
