He buys twitter at an inflated valuation. Runs it to the ground to a much lower valuation of $9B. [1] Then, his company Xai buys Twitter at a $33B, inflating the valuation up. Then SpaceX merges with Xai for no particular reason, but is expected to IPO at a $1T+ in the upcoming years. [3]

I’m not that smart, but if I were, I would be thinking this is an extended way to move the losses from the Twitter purchase on to the public markets.

This isn't really true, though? The ISS does it with radiators that are ~1/2 the area of its solar panels, and both should scale linearly with power?

Setting aside the possibility it's window dressing for a financial bailout, there would be two ways compute in space makes sense:

1) new technology improves vacuum heat radiation efficiency

2) new technology reduces waste heat generation from compute

All the takes I've seen have been focused on #1, but I'm starting to wonder about #2... Specifically spintronics and photonic chips.

Maybe Karpathy has been hired to design a Full Self Cooling system.

It's a con, his AI business is failing, so he's rolling it up into the profitable business. Did a similar thing with Twitter.

This is so obvious, but it's so stupid and at this scale that people find it hard to believe.

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.

> It's extremely difficult to keep things cold in space.

This is one of those things that's not obvious till you think about it.

It's such bullshit that we've decided this moron and others in his cohort can unilaterally reallocate such vast portions of humanity's labor at their whims.

This is an extremely stupid idea, but because of our shared delusion of capitalism and the idea that wealth accumulation at the top should be effectively limitless, this guy gets to screw around and divert actual human labor towards insane and useless projects like this rather than solving real world problems.

Just put a fan in a window.

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.
