Besides, let's not pretend that funding lesbian theater troops in Ireland was in some way in our national interest. There was quite a lot of USAID funding that simply went to fulfilling some private political goal instead of our national interests.

Ok. So precisely how much USAID money was spent "funding lesbian theater troops in Ireland" ?

It's your example, defend it: Give us the numbers, and cite sources.

reject any AI-generated text in human-to-human communications, saying it's "a basic principle of respect"

I cannot agree more with this sentiment. It feels outright insulting to asked to read LLM output in a context where it is *supposed* to be human feedback. Tell me what you would have told the LLM to say, I can take it from there. I don't need you to LLM it up, because it will bury your point in a bunch of crap.

Could it provide useful info? Maybe, but I can do that myself if so. I want *your* thought on something, however incomplete it might be.

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.

Bingo. They have already put the paperwork in place to build pipelines to ship in the nat gas so that the launch cadence is 1/day. Currently they truck in I think I saw around 650 thousand gallons of methane for the fuel for a launch. I figured it is about 1% equivalent of all the gasoline burned in tx for transportation for a day. And because elon really likes no dependencies, he has his own wells as well. I still think it is beyond stupid as an idea, but the leon lovers lick it up. It is the heat problem in which there is no solution. And as others have said, if you can get the processing so efficient as to reduce the heat, well then the power requirements drop equivalently and you'd just do it on earth as the load on the grid wouldn't be an issue.

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.

Liar.

I can look out my back door and see the high tide line where my yard becomes the coast. It has changed significantly. During king tides it is wet nearly to my back steps.

Up north in San Francisco, the area of streets (embarcadero?) around the piers near the ferry building commonly go underwater during king tides. When I was a teenager I used to go up there and it was only wet with occasional storm surge waves.

Which is why OP used "cure cancer!" as a joke.

However, much progress has been made. I am alive right now because of a breakthrough cancer therapy that was FDA approved in 2011. (Well after Nixon!)

This fall I am going to get a therapy that mass-replicates your own immune cells in a lab for re-injection. It's so expensive (and has uncertain benefit) that it's not generally available in the UK or Canada yet. Automation will be a key to making it cost-effective.

It's such a complex area, I think information retrieval and computational science / simulation, or AI if you prefer, will help.

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.

When Musk proposed the data center he said the turbines would be temporary. Over a year later and all he's done is add more turbines while not making a single attempt to get a permit. He does this because the surrounding community is mostly poor black people who already have a high incidence of asthma and other health issues.

So no, the articles are not incorrect. He's running unpermitted gas tubines.
