As a SpaceX fan, I am saddened by this news. The only reason for xAI to join SpaceX is to offload Elon's Twitter debt in the upcoming IPO.

This is just what I was thinking.

Twitter (X) owed $1.3B in debt every year in interest since Musk's takeover. This was before re-financing in a higher interest rate environment. The company was losing $200MM+ per year on ~$5B in revenue before the takeover, and there are reports that revenues have decreased by round 50%.

Best case scenario if we accept those numbers is that X makes $3B per year and about half of that goes immediately out the door in debt payments before paying a cent for the entire business to function.

However, if SpaceX acquires X, that ~$1.5B in interest is a fraction of the $8B In profits SpaceX is allegedly generating annually. Further, they can restructure the debt if it's SpaceX's debt, and not owned by X. Investors will be more likely to accept SpaceX shares as collateral than X.

I am concerned, and haven’t seen anyone else point this out yet, that Musk will move Grok’s CSAM generation capabilities to space to be beyond the reach of terrestrial policing. Does this create some sort of legal loophole here so Musk can do this with impunity?

Either this is a straight up con, or Musk found a glitch in physics. It's extremely difficult to keep things cold in space.

Existing satellites manage to keep their equipment that already can consume several kW cool just fine. You might need space for radiators, but there is plenty space in space.

You can line the solar panels and radiators facing away from each other, and the radiators would take up less surface area. I think maybe the tricky part would be the weight of water + pipes to move heat from the compute to the radiators.

There's clearly rhetorical hyperbole happening there. But assuming that thermal rejection is good in space, & launch costs continue falling, as earth-based data centers become power/grid-constrained, there is a viable path for space power gen. The craziest part of those statements is "100 kW per ton." IDK what math he is doing there or future assumptions, but today we can't even sniff at 10 kW per ton. iROSA [1] on t…

Just put a slightly larger solar array on the same equipment on earth?

One of the biggest but most pointless questions I have about our current moment in history is whether the people in power actually believe the stuff they say or are lying. Ultimately I don't think the answer really matters, their actions are their actions, but there is just so much that is said by people like Musk that strains credulity to the point that it indicates either they're total idiots or they think the rest of us are total idiots and I'm genuinely curious which of those is more true.

SpaceX is too big to fail. It's important for national security. I wonder if Elon wants to tangle all his businesses into SpaceX so they are all kept afloat by SpaceX's importance.

Let’s be honest - this is just a way to prop up Twitter/X. It makes SpaceX shareholders subsidize X, and also American taxpayers who are giving contracts to SpaceX for highly sensitive things. The government should ideally refuse to give SpaceX work unless it unwinds this.

Why? The government is paying less for SpaceX than alternatives. It th cheapest and best service.

I suppose one of the ADR’s read something like “…who cares about bitflips, man. Isn’t AI all about probability?”

Knowing the insane level of hardening that goes into putting microcontrollers into space, how to the expect to use some 3nm process chip to stand a chance?

I thought this wasn't viable due to cooling requirements - how do you cool massive amounts of compute when the only option is to radiate it into space - nothing to convect it with? Also, the incredible amount of grift here with the left hand paying the right is scarcely believable. Same story as Tesla buying Solarcity. Board of directors should be ashamed IMO.

Cooling and maintenance (part swaps, etc.) are one of many obvious reasons why this is bullshit. Doesn't stop grifters, tough.

in actual datacenters you often don't even bother swapping parts and just let things die in place until you replace whole racks
