Well they're really heavy.

Google, Amazon, Meta, etc don't have to wait 12 or 24 months for their big data center to open. They already have lots of DCs to cram all the NVidia cards into, right now.

Definitely not true. Meta is building tents for GPU's

And Starlink / xAI is going to shoot them into space. We are simultaneously living in the future and the past.

I highly doubt that. They claim they want to shoot them into space, but I don’t believe a word of it until I see it happen (and see it work). It’s no more real than hyperloop.

DCs in space is hype but actually makes no rational sense when you figure the size of radiators you'll need, and while solar cells are more efficient in space, they aren't that much better.

The Google paper (https://arxiv.org/pdf/2511.19468) didn’t seem too concerned with radiator mass/size when I skimmed it, but maybe I just missed it. My understanding is that if you run the chips relatively hot (and maybe boost with heat pumps? But then you’re not quite as solid state, and maintenance is tough up there), the radiation ability increases enough such that you can make the radiators slightly smaller than the solar panels, and they’d sit on the dark side of the panels. Many people like to point to the ISS system and scale that up, but there’s a big difference between a system assembled in space and meant to keep humans at human temps vs mass manufactured on the ground and keeping things around 100C.

Well, the sun is always up in space, so yeah they're at least 3x better from that alone.

Tents? Like.. where sleep in the woods in?..

I think it's less a matter of space and more a matter of power availability

Musk gonna Musk. You can't take anything that charlatan says at face value.

I haven't used these budget alerts, maybe they are a pain to implement?

They are still not a spending cap of course.

I think this is making at least some waves in google. I literally just got an email from them with the subject "[Action Advised] Review Google Cloud credential security best practices"

A slew of recommendations, one of them being:

Disable Dormant Keys: Audit your active keys and decommission any that show no activity over the last 30 days.

(Although I don't think this even addresses the underlying issue)

sounds like they want to have customers be responsible instead of fixing it themselves ...

Will someone think of the shareholders? /s

You're not even supposed to take Teslas in a car wash. Countless photos and videos online of flooding Tesla interiors when it's raining or in a car wash.

I don't think water is the platform you want to boast about for Teslas.

As The Register used to call it, these clean-sounding process nodes (15nm, 5nm, 3nm etc) are "marchitecture." Marketing architecture. Reality is much messier.

Thanks for the informative presentation!

thanks for the HN community - the video is how I ended up here and its one of the few social media-esque sites I bother visiting. Taught me a pile of things about coding and CS that weren't in my mechanical engineering degree.
