Yeah, Musk could definitely drive the whole thing sideways. I'm afraid he might be getting increasingly detached from reality. I'm not so worried about the lack of focus on the chomper; it seems to me that the real issues facing Starship are all about how to handle re-entry heat. Also engine re-lights, but I have little concern they can solve that; it's been done many times before, including by SpaceX. If they can solve the rapid reuse after reentry problem, something no one else has done, ever, building various form factors will be a simple matter of engineering.

720,000 people left the labor force

This is the blandest, most watered-down way to say "lost their job" yet. Quite nauseating.

That's absolutely not what it means.

"Left the labor force" doesn't mean "they lost their job" it means "they aren't looking for a job". Examples of cases where people "leave the labor force" include (but aren't limited to):

* Retired.
* Had a child and decided to become a stay-at-home parent.
* Decided to spend their time caring for an elderly relative.
* Decided to go back to school.
* Gave up on working after being unable to find a job.
* Had a financial windfall and decided to stop working.

And so on. The "gave up after being unable to find a job" is not particularly likely in a job market where only 4.2% of people who want a job don't have one, though I suppose some may choose not to work rather than work in a less-desirable job than they had before.

Also, it's July 2. June employment numbers are basically worthless at this point. Give them a quarter or so to get more data and correct the numbers. The initial numbers are based on only on employer reporting data, which skews it in various ways. The government uses several other data sources including surveys, but it takes time for that data to come in, which is why these numbers are generally corrected 2-3 months after they come out.

The only way you can lose heat in space is through radiation. But radiation carries momentum. Not much per photon, but it was enough to cause the Pioneer probes to move in unexpected ways. This means you have to emit equal amounts of heat towards Earth and towards space. If your resultant is zero, then you're fine. You can even direct some of the heat backwards. It won't do a huge amount, but every bit of atmospheric drag you overcome, the less fuel you need to use to stay in orbit.

So you basically need absolutely gigantic radiators behind the space-based data centre, located inside a parabolic dish that will generate drag of its own (not to mention a potential difference betwen the lower and upper sections).

This is an insane level of complexity. You're better off parking it in a stable orbit between the Earth and the moon, so it's absolutely clear of atmospheric effects. You're still going to need radiators, but it's marginally better as you don't have to do quite so much directing of it. The latency would be horrible, maintenance would be next to impossible, and there's all kinds of other issues to consider.

No, I don't think you can make this workable.

However, space might be useful. This very same issue of heat only being radiated means that you can make wafers with much more even loss of temperature, no dust, bacteria, or dirt, and much lower gravity. If you were to make extremely high quality wafers (silicon or gallium arsonide) in space, then you should be able to make WSI processors, which should in turn reduce the demands that datacentres make.

The time it would take to set all this up would be about the same time as it took for IBM to perfect its stacked transistor topology. Intel was talking 90 cores per wafer-scale CPU a few years back - the shrinkage in transistors since then plus the x10 density IBM proposes might push you to 1800 cores per wafer, provided you can get the quality high enough. Which, in space, is quite possible.

You wouldn't need your datacentres in space. Your wafer-scale CPU plus packaging would be about the same size as a CD drive. You could pretty much dispense with datacentres at that point. A typical tower will have two spare bays. "Cartridge datacentres" could simply be plugged in as needed. A regular CPU-based cartridge for heavy general-purpose computing, a GPU-based cartridge for LLMs. Yes, home users would have power usage through the roof, but then it's no longer your problem.

... it's just another pack of lies like everything else Musk hypes up.

Counterargument: Who would have predicted a few years ago that one private company would dominate global launch, launching more by every metric than the rest of the world combined, and -- all by itself -- triple the number of satellites in orbit in 7 years.

Sure, 200Xing the satellite count is a lot harder than tripling the satellite count, about 66 times harder. But if Starship is successful (by no means a given, also far from impossible), SpaceX will reduce per-kg launch costs by 100X, maybe more.

I'm skeptical... but I would also not just write it off as a "pack of lies". The things SpaceX is actively working on should make the launch part of it feasible. Will it be cost-effective? That's a harder question, and heat dissipation is the core thing that may make it infeasible.

Also, the final paragraph of the summary seems to be confused:

So, why are the hyperscalers hyping orbital data centers? Answer: because it's lucrative. "The Elon Musk part of it is honestly genius because he's got xAI building the data centers, SpaceX sending them to space, and Tesla building solar panels," Genkina says. "It's almost like he's paying himself."

Yes, SpaceX will be incredibly lucrative if it owns the whole vertical stack, building, launching and powering -- but only if it works. If it doesn't work, and if orbital compute isn't cheaper than planet-bound compute, then SpaceX will have no buyers.

The other possibility is that it's just a pump and dump, but that's not how Musk has ever worked in the past. Yes, he makes crazy promises, and delivers only half of them, and delivers years after the promised date, but those half-realized, years-late results are still often world-changing.

We all know you ain't bankrolling it yourself, and the people you seem to think will pay for all this wont.

Doesn't really matter because it has to be done, unless we want to pay the much, much higher costs of just living with the hotter planet. We're all going to pay, one way or the other. It's just a question of whether we want it to be expensive or really, really expensive.

I think satellite data centers are colossally stupid, but I suspect the larger problem is the public's gullibility for big lies.

Now, which things ARE lies and which aren't has been delightfully co-opted by politics; what one puts on that list is *instantly* translated into political affiliation.

I can think of 3 big lies that would immediately get me labeled "stupid maga fuck".
I can think of 3 others that would likewise get me labeled "woke fag".
Amusingly, putting all 6 in a list would be cognitively negatively filtered; each "side" would only see and respond to the ones they DISagree with, in most cases as if the others weren't even present.

I think data centers in space will be inevitable WHEN WE LIVE THERE and some research to address the (large) physics challenges the context poses are a good idea. Anything above research trial scale today is dumb. But that's all noise compared to the bigger problems, this argument is only a symptom.

I'm not sure you'd need to pay much. Already I've seen power prices go negative in TX on ERCOT's site. I expect that is somewhat accounting only. I thought some power is priced ahead and committed at a given price and then there is the "open market" which covers surprises. So if wind/solar has a better than expected day, there are days they get nothing for it. So I'd expect those days they'd take a ten bucks a MWH and be ahead.

Right, and it will have extremely good days because of seasonal variation. If we size our systems to provide most of the winter load, there will be a lot of excess power in the summer, and while batteries will continue to get cheaper, I don't think they'll get cheap enough to timeshift from summer to winter. Long-distance power transmission also doesn't do much to address that problem, unless it's really long distance.

I think before when battery tech was much more expensive this would have been a possibility. With battery prices what they are now and falling, I expect the more likely scenario is that batteries get bought to store the excess. And given AI insatiable appetite for juice, I expect every watt that can get built will get consumed. I think I saw consumption today on the ERCOT grid is projected to be around 85GW peak. And it is not even hot yet. I remember just a few years ago 85GW would have been record consumption territory. Now it is meh. The good news is I think a little over 50 of that will be wind/solar today. Not positive, but I think fossil production may actually be down a bit this year relative to 5 years ago. Renewables in TX and batteries shoving up to 8GW into/out of the grid regularly. Who'd a thunk.

Maybe, but if there's a useful place to put excess production it can definitely be more cost-effective to do that... and carbon recapture is definitely something worth doing, and could probably be done intermittently. We just need a way to pay people to do it, pay them enough that it's worthwhile. Note that it doesn't have to be worthwhile now, we can new tech that makes it more efficient, but the pay on offer has to be high enough that people think there might be some path to profitability.

Nobody's pursuing such initiatives. Doing so would be even more expensive than net zero emissions policies.

We definitely need to start pursuing it, at least researching it. We'll never solve the climate change problem with emissions reduction alone, recapture and sequestration will be essential.

There are some strategies which are pretty cheap, such as planting forests. But the numbers don't add up on that; we'll need more. I think carbon recapture systems may pair fairly naturally with renewable energy generation, though. Renewable variability means that in many cases it makes sense to overprovision. For example, in order to get sufficient power generation from a solar plant on cloudy days, you may install 2X-3X as many panels as you'd need for a sunny day... but that means that on sunny days you have lots of excess production that might be hard to use (I experience that with my rooftop solar; last month I generated just over 1 MWh that I couldn't use and the grid wouldn't pay me for). Using that excess to power carbon recapture would be a good idea.

For that to work, though, we need to arrange some financial reason for people to build and operate carbon recapture systems. That's a big missing piece which only government can solve. The obvious solution (to the entire climate change problem, actually!) is refundable carbon taxes plus carbon tariffs.

I'm amazed that any company relies on anything from Google...with them shutting things down and deciding not to provide services to huge chunks of the world. I guess it's time for me to review my use of all things Google, again...

If your concern is that a product you use might be discontinued, there are some simple rules that you can apply to decide whether a given Google product is safe from being discontinued:

(1) Is it used by 100M+ people? If it is, it's safe. If the number is 10M+ it's probably good, but there's a risk. If it's less than 10M, it probably won't last. Unless...
(2) Is it a paid service? Paid services rarely get shut down, and if they do Google bends over backwards to make t right.

If it's free and has a small (for Google) userbase? It's all but guaranteed to get shut down. Google is a business. They make a lot of products that are free to use, but only because they can bundle ads with them or otherwise profit from them, but free-to-use products require a large user base to generate much revenue.

It's not anywhere near one step away. Designing the peptides and getting one or more candidates is the easy part. The next steps are the hard ones, the ones that make pharmaceutical chemists and drug researchers cry:

  • Phase I trials to see if it even works as claimed. Expect a 95+% failure rate here. Note that this is where you're going to see the best results for your drug candidate, things never improve from here. The best you can hope for is that they don't get any worse. So if you don't get strong results here you're probably wasting your money.
  • Phase II trials to determine the best dosage and pharmacokinetics. Again expect a 95+% failure rate here, and results showing less effectiveness than shown in Phase I.
  • Phase III trials to determine behavior in a large sample representative of the target population. Expect a failure rate upwards of 99% here, and a major drop-off in effectiveness. This is where toxicity and serious negative side effects show up, and those can kill your trial dead even if your candidate is working.

Getting through this process will take multiple tries and years of work, assuming you succeed at all. There's a reason they say that the clinic (clinical trials) is where drug candidates go to die.
