gregbot··on Israel's AI targeting system: how data from a phone become a death sentence
>a small village less than three miles from the Israeli border which had turned into a battlefield during Israel’s campaign against Hezbollah in 2024.

Classic New York Times style writing. This sentence should say “Israel attacked this village as part of its invasion of southern Lebanon and Hezbollah defended it”

Imagine if this whitewashing were done to Russia: Karkiv, a small city 10 miles from the Russian boarder which had turned into a battlefield during Russia’s campaign against Zelenski in 2022”

This made me absolutely livid:

> We requested a security incident report from the ethical hackers as proof

So instead of paying him a fair bug bounty, they demand that he write a formal report for them and prove to them that there is even a problem.

Totally unhinged, but it gets worse:

> the response was a demand for money for the report, which confirmed our suspicion that this was a ransom-related incident.

Wow. So when the security researcher informs them that he would be happy to do some consulting work for them and informs them of his rates, they flip out and accuse his initial good samaritan decision to inform the company of the issue of being part of a plot by him to hold the company for ransom?

Whoever thought this is both totally delusional and a complete jerk. Truly, no good deed goes unpunished.

gregbot··on Is liberal democracy in terminal decline?
So do you oppose DACA? That was the executive deliberately refusing to enforce the law as passed by congress.

Edit: Here’s what a federal judge had to say in 2023: "The solution for these deficiencies lies with the legislature, not the executive or judicial branches. Congress, for any number of reasons, has decided not to pass DACA-like legislation ... The Executive Branch cannot usurp the power bestowed on Congress by the Constitution — even to fill a void." https://www.npr.org/2023/09/14/1199428038/federal-judge-agai...

> Also, as an aside, if the bad actors in government who were screeching about DACA's constitutionality put even a fraction of that effort into protecting the Constitution when the First and Fourth Amendments were on the line, that would be great.

This is actual whataboutism

gregbot··on Iran report says 16,500 dead in 'genocide under digital darkness'
Its remarkable to see the propaganda shift from “these are unarmed protestors not terrorists with guns” to “they are terrorists and they should have had more guns”.

I’m just glad President Trump didn’t start Iraq War 2.0 with this unrest as his WMD excuse.

> Investing into renewables brought prices down by creating an economy in scale, which for nuclear never has worked

Never worked? How do you explain all the countries in the world with large low carbon nuclear fleets and reasonable electricity prices? Like France, Japan, Korea, Russia, China, the US, Canada, UK, Sweden, Finland, Ukraine etc? Everywhere large nuclear fleets have been built with a dozen or more reactors the per unit costs have been affordable.

None of that really matters though because when you look at the full system cost of intermittent renewables, they are an order of magnitude more expensive than the marginal cost.

In 2023, coal-fired electric power plants accounted for 86% of West Virginia's total electricity net generation

Looks like west virginia is still a state where hybrid-electric vehicles have lower emissions than all-electric ones. Who knew.

gregbot··on Photos capture the breathtaking scale of China's wind and solar buildout
Arguably yes! But it avoids a lot of the safety and environmental hazards of traditional methods.
gregbot··on Photos capture the breathtaking scale of China's wind and solar buildout
US NREL Puts it at $2/W with no storage and ~20% capacity factor. Lifetime of latest panels is unknown but optimistically is 25 years. Assuming perfect and free storage that comes to $24.4 billion per year of capital expenditure for a country the size of France to be 100% solar. So no, it would not be more economical to use solar over nuclear. Wind would be better but when you add the full system costs of storage and backup intermittent heavy systems are vastly more expensive and emit more carbon than nuclear ones. https://discussion.fool.com/t/levelized-full-system-costs-of...

Intermittents are only gaining market share because their unreliable and intermittent power which is less valuable is being purchased by governments at prices that far exceed what it is worth. In other words, massive hidden subsidies. Without those, there would be next to no intermittents on the grid anywhere.

See “Market matching costs” here: https://en.wikipedia.org/wiki/Cost_of_electricity_by_source

Nonsense? Why was US nuclear built at all in the 60’s and 70’s? Or in France? Because it was cheaper? No. It was built because people thought it was a good idea. The same is true for intermittents today. They are popular with a section of the population so they get the funding. And no, nuclear has fantastic experience curves. Look at any country building lots of reactors and the n-th of a kind is cheap. Building out nuclear and maintaining industry experience works to keep costs low.
gregbot··on Photos capture the breathtaking scale of China's wind and solar buildout
Great. So 538TWh per year is 61 GW so roughly 61 GW * $9.38 = $576 billion staggered over the 80 year life of nuclear plants is $7.2 billion per year of capital expenditure.

For comparison, wind is about $5/W. Assuming a 35% capacity factor and a 30 year expected lifetime for the latest turbines that comes to $10.0 billion per year of capital expenditure with no storage or fossil backup systems or extra capacity given weather variability.

gregbot··on US electricity demand surged in 2025 – solar handled 61% of it
Ahh yes. France’s investment in replacing carbon free nuclear with… carbon free intermittents. Fortunately that hype-driven waste is not stopping France from building out new EPR2 reactors.
gregbot··on Germany's Merz admits nuclear exit was strategic mistake
No, what you are saying is a bunch of nonsense. If germany had simply kept its nuclear plants running and replaced its remaining coal with new nuclear back in 2000 instead of going with wind and solar it would have as low emissions as france by now. The decisions to go with wind and solar instead if nuclear meant keeping fossil fuels on the grid
gregbot··on Germany's Merz admits nuclear exit was strategic mistake
Well, the only real downside to this is that energy is a bit more expensive and emissions won’t go down significantly for an extra 15 years or so. Depending on your preferred social cost of carbon that could not matter to you.
gregbot··on Germany's Merz admits nuclear exit was strategic mistake
I highly doubt german reactors were designed to only last 35 years. Most gen II light water reactors in the US are expected to operate for 60-80 years.

Edit: ah i reread and see what you meant but my point still stands that 45 years is abnormally short for the type of reactors they had

gregbot··on Photos capture the breathtaking scale of China's wind and solar buildout
>There's no market for them

In an economic sense, when compared to burner reactors, this is correct. As the rise of wind and solar has shown however, political will and popularity matter more than pure economics. Burner reactors are more of a 22nd century technology, assuming the grid storage problem doesn’t get solved by then and we just go full renewable on economics. But nothing is set in stone

I await your updated study to back up your claims
gregbot··on Photos capture the breathtaking scale of China's wind and solar buildout
Ah yes. “Old” plants. This plant is “old” so we could never build more like it. What an argument. And no, they would not be “considerably more expensive” because we wouldnt build a fleet of them until uranium was expensive enough that they would be cheaper. Thats why most countries have put off breeder reactor development not because they were “failures” whatever that is supposed to mean.
gregbot··on Photos capture the breathtaking scale of China's wind and solar buildout
Yes it is. Here is the study

Proven Uranium reserves with breeder reactors will last 10,000 years. With a modest increase in the price of Uranium, extraction from sea water becomes viable and unlocks tens of millions of years of supply. Some geologiats have argued that rock weathering will replenish sea water Uranium concentrations faster than we would extract it making the supply last longer than the expected age of the Earth.
gregbot··on Photos capture the breathtaking scale of China's wind and solar buildout
Well if by close to nothing he means waste lasting 300 years instead of 10,000 years and by latest generation he means gen IV reactors like bn-800, superpheonix, oklo, moltex etc sure he is basically correct. Here’s a source where you can read more about breeder reactors: (which is what he is referring to)

1GW of nuclear is worth about 3 to 6GW of solar if you account for the weather and nighttime. If you also account for nuclear not needing fossil backup its worth even more

France decarbonized way before the rest of Europe with nuclear and it wasn't expensive. 50 reactors for $200 billion. Gernamy has spent twice that on intermittents and still relies on coal
gregbot··on Photos capture the breathtaking scale of China's wind and solar buildout
Uranium actually does not require mining. Most uranium is extracted using underground wells where water is pumped underground and the Uranium is extracted from the water. Also extracting Uranium from sea water (which would be basically unlimited) is close to being commercially viable and has received a lot of lab-scale research.

Also, Uranium is only recyclable once with light water reactors. With breeder reactors (which have been built in the past) it can be recycled a hundred times.

gregbot··on Photos capture the breathtaking scale of China's wind and solar buildout
it depends where your electricity comes from actually. In west Virginia it comes from coal so is worse than a hybrid but still better than non-hybrid gas cars (in terms of CO2)

Who cares? Those blades and that concrete are totally inert and just sit in the ground after their useful life. The ground already has lots of rocks in it.

The Potassium naturally occurring in your body produces 5400 Bq of radiation. All the Krypton-85 in the atmosphere produces 1 Bq per cubic meter of air. So this is a trivial amount of radiation and not a hazard. https://en.wikipedia.org/wiki/Banana_equivalent_dose https://en.wikipedia.org/wiki/Krypton-85

>even if batteries get cheaper by 50% (and that is unlikely just based on materials cost) its nowhere near enough.
