I'm 55. I have a decade of alcoholism with uncontrolled sky high blood pressure accompanying it. My doctor once pointed to my liver enzyme chart and said, "Your liver is very unhappy with you." Then he pointed at my ECG and said, "See that little bump there? That might be what kills you." I had 18 months with a cocaine problem. For two years I partied hard including every psychedelic I could get my hands on. I spent 40 years out of shape, sometimes ridiculously so.

I'm in good shape now, and across the board my numbers are great. ECG is clean. I'm comfortably retired, and at the gym every day. I'm healthy. If you looked at the snapshot at this moment in time you'd think things could hardly be any better... but I know the damage has been done. I'm on borrowed time.

So if I'm going to spent a few uninterrupted hours on MS Flight Simulator, or slashing my way through a few zones on D2: Resurrected, I'm not going to sweat it. In the pantheon of self destructive behaviour this doesn't rise to the level of consideration.

AD or BC? This matters. If Bill Gates is a time-travelling reptile from the Pleiades, and put chips into vaccines, it could be that all who took the vaccine will be spirited back into the Bronze Age and offered up as human sacrifices.

The truth is way out there.

Your final line is relevant "Quality of life matters."

And for some people, "quality of life" is maximized by avoiding exercise (because they dislike it and so doing it lowers their quality of life) and instead doing computer stuff and eating tasty food. It is true that they will have health issues, but for most of their life those issues are minor inconveniences, and they are maxing out on quality.

Maybe they die at 85 from a heart attack or some other issue related to poor heath, and that's ok with them. The years they gave up were worth the enjoyment they got from the years they had.

Obviously, you have different values. Which is just as valid. We must all make that "existential trade off" for ourselves, and each person is going to wind up somewhere unique on the spectrum. Someone else's conclusions might seem stupid to you, but that is not because the conclusions are ill-informed or unwise, but because their values are different than yours.

The only stupidity is in failing to recognize that.

What makes this an American website? Seems pretty well traveled by folks from most English speaking nations. I, myself, have only visited the states.

A long time ago, back when you had to go to the Unemployment Office every two weeks to turn in your paperwork and get your check, I was told that by a clerk. So far, I've seen no reason not to believe it, even though I've seen supposedly authoritative claims that it's not true. It's the type of thing the PTB would deny even though it's true.

TFA gave me cancer.

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.

Yes, it was all super entertaining, especially with PJ covering all of it, and rarely missing a trick. Good times for those of us watching from the cheap seats. A huge waste of time and resources for IBM.

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.

No, it means that they've lost their jobs and their Unemployment Benefits have run out. The various government agencies responsible for these numbers assume that if you're not receiving government handouts you've left the workforce and they stop counting you as unemployed.

I credit most of SpaceX's success to CEO Gwen Shotwell. She keeps things going even when Musk is off on an irrelevant tear somewhere else.

Unfortunately, Musk seems to be on a path to sabotaging her efforts. The SpaceX prospectus showed that xAI (which bought Twitter, because why not?) was the reason they posted a loss in the last fiscal year. Even with all the expenditures on Starship, SpaceX would have been profitable. Like every other major AI company, it is not at all clear that xAI can reach profitability anytime in the near future, especially since xAI is blocked from so many enterprises and doesn't seem to be able to keep up with the big three at all. As Starship production scales up, the costs are going to increase, and they need payload revenue to offset those costs. There's so much focus now on the Pez dispenser and the lunar mission that I haven't seen any hints of the conventional payload delivery version (aka, "Chomper") in a couple of years. Maybe it's being quietly worked on. I hope so, because the big space station payloads that were talked about a few years ago will need it.

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.

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.

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.
