You guys clearly didn't read the full blog post where Musk mentions lunar mining. They're going to put an ASML machine on the moon and turns regolith into chips and solar panels automatically. Literally free compute
What data centers in space enable is protection for the compute of near-superintelligent AIs from the interference of humans. As an alleged human, I'd like to preserve my option to interfere.
What’s there not to like? Superconductors. Free electricity. No cooling necessary. Put those three together and maybe it’s possible to push physics to its limits. Faster networking, maybe 4x-5x capacity per unit compared to earth. Servicing is a pain, might be cheaper to just replace the hardware when a node goes bad. But it mainly makes sense to those who have the capability and can do it cheaply (compared to the re…
> No cooling necessary. This is false, it's hard to cool things in space. Space (vacuum) is a very good insulator. 3 are ways to cool things (lose energy): - Conduction - Convection - Radiation In space, only radiation works, and it's the least efficient of those 3 options.
Earlier quoted context omitted.
Well this explains why, but does not answer how to get rid of excessive heat in space.
What kind of the problem you're talking about compared to existing satellites? That is, all existing satellites generate power, and need to dissipate that power, and most of it goes to waste heat, and the satellites somehow do that successfully - what is the specific problem you're talking about, which can't be solved by the same means?
I would not assume cooling has been worked out. Space is a vacuum. i.e. The lack-of-a-thing that makes a thermos great at keeping your drink hot. A satellite is, if nothing else, a fantastic thermos. A data center in space would necessarily rely completely on cooling by radiation, unlike a terrestrial data center that can make use of convection and conduction. You can't just pipe heat out into the atmosphere or build…

Do you mean to suggest that computer hardware does not need to be cooled when it is in space? Or that it is trivial and easier to do this in space compared to on Earth? I don’t understand either claim, if so.

I'm convinced that >30% of this comes from ideas leaking out of fiction such as like Neuromancer , and percolating through the minds of wealthy people attracted to some of the concepts. Namely, the dream of being a hyper-wealthy dynasty, above any earthly government, controlling an extraterritorial Las Vegas Fiefdom In Space. (Which in the book, also hosted a powerful AI.) Then they work backwards, trying to figure o…
So whenever I see here or anywhere else that your ideas mean nothing I just laugh at it. Of course, these come from people who are bland, doesn't have any imagination and they are not creative at all at all, but they have brute force, which is money.

You can reject the heat by shedding hot mass, but only once.
Where will they go, nobody knows!
