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…

To Steelman the topic, Musk’s whole alleged mission is to make humans a multi-planet species that can survive an earth killing event. To that end, a small data center space isn’t about unit-economics, it’s a bigger mission. So the question we should consider is what can we put into space the further that mission. Can we put a meaningful sum of human knowledge out there for preservation? It sounds like “yes,” even if…

Let's say there is an earth killing event, and let's say there is an outpost on Mars with some people on it. How much does it really matter that some humans survive, in light of the enormous catastrohophe that killed all life on earth? Is it a very worthwhile objective for our species to persist a while longer, or should we not just accept that also life itself will will die out on geological or astronomical time scales?

Do you know the lifespan of those satellites? Do you know how many of those fall out (sorry, de-orbited) of space every year?

Do you know the cost of sending up a payload of them?

Do you know how much $$ you need to extract from those payloads to make the cost of sending them up make sense?

Do you know how much they've lied about Starlink revenue and subscription counts?

Superconductors.

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.

Superconductors. Average temperature in space is around 4 K.

Musk's whole mission is to scam even more people. Unfortunately people still buy his bullshit even though he couldn't deliver on anything, and just converts one failure to hyping up his next idiotic product.

(Yes, I know what steel manning is)

Why is there no cooling necessary?

Space is cold - 4 K. Superconductors.

It's lala land nonsense.

- Data centres need a lot of power = giant vast solar panels

- Data centres need a lot of cooling. That's some almighty heatsinks you're going need

- They will need to be radiation-hardened to avoid memory corruption = even more mass

- The hardware will be redundant in like 2 years tops and will need replacing to stay competitive

- Data centres are about 100x bigger (not including solar panels and heat sinks) than the biggest thing we've ever put in space

Tesla is losing market share (and rank increasingly poorly against alternatives), his robots are gonna fail, this datacentre ambition needs to break the laws of physics, grok/twitter is a fake news pedo-loving cesspit that's gonna be regulated into oblivion. Its only down from here on out.
