Hell, even tangentially involved. I'd make his list of mortal enemies on multiple counts: Working on developing adjecent tech, using Copilot , and legitimizing them. My research would probably make most of the problems he's talking about a lot better (less data and energy hungry models), but apparently I'm still on the list.
I'm not sure how I feel about the body of the article, but the last two paragraphs are the only ones I have confidence in my assessment, and my assessment is poor.

To be fair, you have customers willing to buy it. So whatever it is you're doing, there seems to be enough demand for it to justify what you're doing. I'm in the same general line of work, just slightly different methods. Right now the AI space is a bit overrun with so many ventures and we haven't really figured out which ones deliver real value long-term, but there certainly is enough signal there in the noise, of projects that bring real benefit to real people. In the healthcare space, those benefits can be worth 10s of thousands of dollars per patient, so it's not like we're turning electricity into heat for shits and giggles. Even those of us not working in domains that so readily show their net benefit to society.
And to be fair, those KfW40 houses are quite efficient. Almost a solar array and a ventilation system away from passive houses. Buut, doing the math helped me square away how a seasonal heat store for you seems so unreasonably large, when it's doable for some low-energy homes. If you cut the yearly energy store by 10, triple the energy density because you're running your thermal battery from -1°C to 40°C, then you'd end up needing ~12 cubic meters of water to heat a KfW40 home through one winter, and in the summer that's your heatsink for AC. 12 cubic meters is still a lot, but it starts to get reasonable.

Not that you suggested it, but it might just work: Whatever water your heatsinks dump their heat into, you pump that stuff into a cooling tower. In there, you simply spray the water around, collect it back up, and pump it back inside. I hope your neighbors like their balconies humid...
I am, by the way, imagining the jankiest possible solution: Big plastic bucket for the tower structure, some plastic pan as a sump, aquarium pumps everywhere, and a shower head to produce the droplets.
Given Greg just took a very janky idea a bit too seriously, I'm afraid to submit this thought...

I've done some math. With 2kW, you'd actually need a fairly decent tank to store it all. If you're just working with, say ~40°C deltaT, then you can expect a daily cubic meter of hot water. You'll get three times more mileage if you're also using the melting point of water (that alone is a cool 300kJ/l), but at that point the complexity of the system explodes. And with the amount of energy you'd need to store in a year, building a seasonal heat battery is out of the question, unless you want to convert the entire flat next door too.
(Edit: As a point of reference, Germany subsidizes low-energy homes. One class of low-energy housing, called KfW40, requires at max 15kWh/a/m^2. At 100m^2 of space, that's 170Watt. To heat a home. That's it. You're dealing with 10x as much heat, no wonder you're struggling to get rid of it.
Yeah, out the balcony it is I believe.
BTW, what you're doing right now, perpetually open window in the winter? I've heard that sarcastically called "heating for the air force".

Is there a substantial heat store there, e.g. a hot water tank? How your home is heated is, I believe, mostly irrelevant for the question of how to cool it down, but might not hurt for completeness' sake. How is your home cooled? And most importantly (IMO): Is it a necessity to sit your sweaty ass right next to your multi-GPU workstation, or could you put it in a server rack in the utilities room, interacting either via remote-ssh or via periphery cables run through the walls? Also, just how many watts of compute are we talking about here? Also also, what's your home like? Single family house? Any utility spaces that you could use and/or pollute with the extra heat?
Counter-questions aside, here's the high-effort, high-reward solution. I don't think most of this exists as off-the-shelf components, but who knows.
Put your machine next to wherever your hot water is made. Suppose you have a storage tank for hot water next to the rig. Whenever you run your rig, cold water from the utilities is brought in, cools your machine (should only really be at a trickle; water can soak up a lot of heat.) and is thereafter stored in a tank. That tank is either your primary hot water storage tank, or is used as the primary source of fresh water for your actual hot water storage tank. Yaaay, your hot water in the summers is now completely free. Did you want to take a hot bath?
Admittedly, this solution makes the eco-nerd in me very happy, but I don't think it's very plausible. One, depending on your compute needs, you might struggle to use up as much heat during the day in the summer. Running a few GPUs hard might get you into the 1-2 kW range, at which point we're talking about the electric power of a kettle that can boil a liter of water in a few minutes. Kinda hard to use up that much hot water during a hot day. If you end up going for something like this, I'd say you definitely need to talk to a plumber.
Perhaps a bit more realistic is to find a more passive heatsink. Fewer moving parts and such. Maybe a concrete floor in the garage or something... But I can't quite put that together without a bit too extensive renovations. Give your garage underfloor heating, and hope that it soaks into the ground mostly? Seems a bit too high-effort for the problem.
I guess if I want you to take anything away from my ramblings here, is that there might be space for a good solution if you move your machine away from your desk, but keep it under your roof. Even if it means that you let it heat your garage up to slightly-uncomfortable temps.

Even for the simple task of randomizing/blinding I think I could've come up with something slightly better with the help of one reliable assistant for some one-time menial set up work: Repackage the pills, and give them a random ID in the process. Assistant records the ID-group mapping (i.e. #1 is control, #2 is intervention, ..) and holds on to the mapping for later analysis. Principal Investigator and today's D-class subject of the day in personal union then proceeds to grab a random packaged pill, records the ID and proceeds with any other recorded variables.
Similar for the issue of deliberately sampling low-mood points, which the author later addressed by sticking to a schedule.
That said, the analysis of the result is fairly decent. Not that I'm in the relevant field, but if I were reviewing this work in the right venue, I'd actually not be completely put off. That said, if you're committing to a 16 month study, and you want to publish it, better make sure your methodology is cromulent before you start, ideally with the help of the kind of people who'd end up reviewing your work.

This so much. Say you rock up on friday on your third day of being sick. Your doctor might tell you to stay home all of next week, if they think that's the amount of rest you need to get better. Which is miles better than a more informal "oh, just stay as long as you need to get better", because then every morning you play the inevitable game of "am I fine yet?", and you think you're fine, only to feel like dog shit come 5 PM. Whenever I have the pressure to actually get work in, I tend to play this oscillatory game of "I'm fine", "lol you're not, get back to bed" for a few days at the tail end of any infection. When I don't have that pressure, I think recovery actually goes significantly faster.

Well, I think kej's intention was to treat it more or less as a shadow ban. And shadow bans aren't exactly being announced to the user. And while shadow banning is easily detected if you go looking for it, having your own votes just routed to nirvana would be undetectable because of vote fuzzing.

We're only hearing one side here; ICE hasn't commented on the matter AFAICT. But supposedly she had her gear on her and was offering appointment bookings in the US. If she then proceeded to say that she did not intend to work in the US, then the crime is already completed. A crime that the US threatens with up to 10 years.
The question in my mind is more, does the punishment fit the crime (no, not until the US penalizes tax evasion of a few thousand dollars by 10 years in prison) and whether her treatment was justifiable. (hell to the no, if we believe what we're hearing, it was/is essentially torture.)

Both 1 and 2 sound just a little insane. 4 is routinely applied to less severe cases.
I guess the best thing I could come up with is to allow foreigners to waive their rights to be present at the hearing, then deport them and hold the trial in absentia. Whether waiving your own rights like this is even constitutionally legal in the US I can't say.

The reason I've heard for this is that they want to have a judge determine all this, so they can permanently bar her from entry. That's impossible when she's home, because her constitutional rights guarantees her the right to attend her own trial, so you can't kick her out before the trial, hence this detention....? Also, this whole lying under penalty of perjury is a pretty big deal - max 10 years of prison, so if she ends up detained for a few months and then deported without option of ever reentering the country, that's, for some definition of the word, going easy on her already.

(2): The framing of the victim as tourist is... tenuous. Supposedly, her Instagram indicated she planned to do actual work for customers in the US. On a tourist visa. So, looks a whole lot like a legit visa violation.
(3): In spite of (2), (1) bears repeating.

If both birds are moving at mostly constant velocities, then a collision implies that there was zero relative movement of the light source. That can easily be lost visually. Also possible that it was the wrong bird to begin with, and the plane was simply in a blind spot (frame in between the cockpit windows perhaps?)
Keep in mind that in night flying, you mostly just see the navigation lights, not the hull itself, so distance cues are mostly N/A.

ATC in the US has been somewhat dicey already before, if observations on LiveATC are anything to go by. A concerning number of bad calls and near misses. I remember lots of commentary along the links of "just a matter of time till we run out of luck". So it's possibly a preexisting condition, and not caused by Trump.
Then again, ATC are federal employees, right? I suppose the current climate isn't exactly conducive to good job performance.
I dunno about you, but last I checked, they do have those huge disclaimers that it makes up crap. It's kinda hard to miss.
It's still a useful product for other applications.
And, as Turtle pointed out, we have no way of knowing the prompt that led to this. I could easily tell chatGPT a few things about myself, such as that I killed my children, then talk about the weather for a bit, and later ask the model what it knows about me. When the model then inevitably tells me the only detail it can reliably infer, does that make it defamation? Hell, is it even defamation if I didn't directly try to cause it? After all, all I can show is that I was shown this information. I can't even credibly assert the existence, much less the identity, of any other person who I was defamed to. The statements also weren't made publicly.
There's so many unknowns in this story that would need to be plugged for it to hold water. As it is, it's pretty much "man yelling at cloud".
