I know many people smarter than me, plenty of them who have spent careers building data centers, and not one of them think this is plausible.

You should consider whether people smarter than the average investor are pulling a fast one.

Maybe we are talking about different things here?

I don't doubt spacex can fail at this.

I also don't doubt we are fairly close to making this plausible.

> plenty of them who have spent careers building data centers

Famously, plenty of people who have spent careers building rockets would swear that reusable rockets would absolutely never work.

>I also don't doubt we are fairly close to making this plausible.

Maybe you should doubt that. There's literally no reason to think this is plausible besides some hype merchants' say-so.

Excluding Spacex:

Nvidia, Google, China, European Commission, Blue Origin

And this being HN, a YC funded company has put a single GPU rack in space and demonstrated training a reasonable sized model on it.

But yeah, it's all hype, sure.

		On the off chance you're sincere and not just heavily over indexed into Elon stocks: It's trivial to understand why this is all hype if you pay attention to physics, as another commenter suggested earlier. https://en.wikipedia.org/wiki/Stefan%E2%80%93Boltzmann_law Assume you're radiating away the heat for a single B200 (~1kW), and the max radiator temp is 100C, you find A = ~3m^2. So that's 3 square meters per GPU. Now if you take into account that the largest planar structure deployed into space is ~3k m^2 (https://investors.lockheedmartin.com/news-releases/news-rele...), you're looking at 1000GPUs. That's a single aisle in a terrestrial data center. Cost to deploy on earth vs satellite is left as an exercise to the reader.

Have you considered that people smarter than you are scamming you?

Yep, definitely being scammed by not dismissing things outside my area of expertise out of hand.

I wish I had your confidence about everything!

		Just ignore him. Nothing of value will ever be generated by him, including text.

		I am yet to see any actual numbers showing how the economics of this would work or compare to the cost of building traditional data centers. Please come back to reality.
