Where's the government bailout in this transaction that would make this a relevant comparison?

#493> it is possible to put 500 to 1000 TW/year of AI satellites into deep space, meaningfully ascend the Kardashev scale and harness a non-trivial percentage of the Sun’s power We currently make around 1 TW of photovoltaic cells per year, globally. The proposal here is to launch that much to space every 9 hours, complete with attached computers, continuously, from the moon. edit: Also, this would capture a very trivial…
In fairness, solar cells can be about 5x more efficient in space (irradiance, uptime).

Re: xAI joins SpaceX
#496It's a CONSTANT stream of new ideas with no payoff at this point. Hyperloop > Neuralink > Self-Driving Cars > Robotaxi fleets > Personal Robots > Orbital Datacenters > [insert next vibe shift] At what point do people start to see the ever-shifting goalposts for what they are?
Hyperloop was never a company project, neuralink was a separate company, tesla is rolling out driverless robotaxis and fsd is amazing, robots inevitably are going to do the majority of work - there’s no real doubt about it is there? Datacenters in orbit seem insane so idk we’ll see
There's a lot of doubt that the AI and compute to enable that would happen on commercially relevant timescales.
Consider: "do the majority of work" is a strict superset of "get into car and drive it". The power envelope available for an android is much smaller than a car, and the recently observed rate of improvements for compute hardware efficiency says this will take 16-18 years to bridge that gap; that plus algorithmic efficiency improvements still requires a decade between "car that can drive itself" and "android that can drive a car". (For any given standard of driving).
And that's a decade gap even if it only had to do drive a car and no other labour.
You can't get around this (for an economy-wide significant number of androids) by moving the compute to a box plugged into the mains, for the same reason everyone's current getting upset about the effect of data centres on their electricity bills.
And note that I'm talking about a gap between them, not a time from today. Tesla's car-driving AI still has safety drivers/the owner in the driving seat, it is not a level 4 system. For all that there are anecdotes about certain routes and locations where it works well, there's a lot of others where it fails.
That said: Remote control units without much AI are still economically useful, e.g. a factory in Texas is staffed entirely by robots operated over a Starlink connection by a much cheaper team in Nairobi.

#4971. What in the circular funding? This feels more like a financing scheme founding it under X/Twitter and then spinning it over to SpaceX. I suspect some debt is disappearing or taxes aren't getting assessed because of this move.
2. The only thing harder than harnessing "a millionth of the sun's power" on Earth would be launching enough material into space to do the same thing. And that's not even a reason for SpaceX to own an AI company, at least not at this point. The current AI isn't going to help with the engineering to do that. Right now hiring 20-somethings fresh out of college is way cheaper and SpaceX has been very successful with that.
quick edit: dang, I even got point 1 backwards. xAI owns X/Twitter, and that means that SpaceX now owns X/Twitter as well as an AI company. Super suspicious that SpaceX could actually think that buying the social media part (a significant portion of xAI's value) would be worth it.

#498Earlier quoted context omitted.
what makes you believe this? radiators can be made as long as desirable within the shade of the solar panels, hence the designer can pracitically set arbitrarily low temperatures above the background temperature of the universe.
Shading does work; JWST does this. However I don't see how you can make it work for satellite data centers. You would constantly be engaging attitude control as you realigned the panels to keep the radiators in shade. You'd run out of thruster fuel so fast you'd get like a month out of each satellite

#499A former NASA engineer with a PhD in space electronics who later worked at Google for 10 years wrote an article about why datacenters in space are very technically challenging: https://taranis.ie/datacenters-in-space-are-a-terrible-horri... I don't have any specialized knowledge of the physics but I saw an article suggesting the real reason for the push to build them in space is to hedge against political pushback pr…
We don’t even have a habitable structure in space when the ISS falls, there is no world in which space datacenters are a thing in the next 10, I’d argue even 30 years. People really need to ground themselves in reality. Edit: okay Tiangong - but that is not a data center.
Re: xAI joins SpaceX
#500I still don't understand the "data center in space" narrative. How are they going to solve the cooling issue?
Remember MoviePass, and how they were losing gobs of money by letting people see unlimited movies for $20/month? It was so obviously stupid that a bunch of people went, "well, this so clearly can't work that they must have a secret plan to make money, we'll invest on that promise", and then it turned out there was no secret plan, it was as stupid as it looked and it went bankrupt. The "datacenters in space" thing is…
