Where was his skepticism? I saw something that looked more like anti-intellectualism then any attempt at being skeptical.

Let us look at what he wrote:

That's what's great about physics. You can say whatever you want in areas that are beyond the capabilities of current science.

People do make conjectures about things that are beyond Science. Think String theory. So how do we falsify that? Hint - we don't, we either accept it because it is convenient, or be skeptical about it. That doesn't stop String theorists from discussion or agitating for their hypothesis. Back to the subject at hand.

If you read the paper referenced here, it does invite a bit of healthy skepticism. They pretty much admit it.

So let's put it to the test using me as the villain.

I think that string theory is convenient bullshit, and that people agitating for it are engaging in mutual mental masturbation. And no, they don't like that.

Does that make me an anti intellectual? It would be the first time in my life I've ever been accused of that. On the contrary, I usually get asked to tone down the big words and simplify things. And since the respondent decided to make it about Trump and his merry band of incompetents, does that make a person who hasn't voted Republican in over 25 years a MAGA?

The respondent who connected the OP with MAGA is at siting at +5 insightful. We live in an age where it is very fashionable and approved to use Cheeto as a way of castigating anyone they disagree with. And truth is apparently irrelevant.

How about some good discussion about the paper? Both the science aspects of the paper, and I think it would be interesting to discuss if disagreeing with or heavily skeptical of the paper is determinant of one's political party.

Looking over the paper, I can see some issues. Assumptions must be made of course, but IMO, there are just too many assumptions made, and they even use Gedankenexperiment in their paper. Gedankenexperiment is good to get a discussion going, because you can use anything at all to forward what you are thinking.

And if a dullard like me sees problems, it might seem that smarter people will as well.

It's not an error because LLMs were never designed or intended to be factually accurate. They were designed to spit out text that passes for text that you'd typically find in the literature it's been trained on. That's it. It's doing exactly what it was designed to do. It's only humans who think that something spitting out text should be accurate.

I have always been concerned that the nature of AI will lead to it referencing itself, which can make it spit out things that are completely wrong, yet somehow become facts. Ironically, the best answer I got was AI generated:

"When AI starts referencing itself, it can create a feedback loop where AI-generated content is used to train new models, potentially leading to inaccuracies and a decline in the quality of information. This process can result in models that produce less reliable outputs, as they may rely on flawed or misleading data from previous AI generations."

And I agree 100 percent.

I know it's fashionable in MAGAland these days to be anti-intellectual, but good part of science is refinement.

I hope you realize that trying to connect this to Trump somehow is kind of disingenuous, and alerts the worker to the concept that politics is as important as science ion the upcoming argument. Not always, but a non-zero chance.

The guy is expressing skepticism, usually considered a good trait in matters of science.

Maybe we should start over again.

The authors of the paper are using a rather large number of assumptions - indeed they admit the paper is a Gedankenexperiment.

And despite some folks disagreement - Gedankenexperiment is more or less mental mutual masturbation. It's more or less normal, despite the rude term. I'm no expert on cosmology, but I left more skeptical after reading the paper.

No. These people aren't saying "whatever you want"; they're presenting the latest evidence-based model, for peer-review and further refinement passes.

Just between us chinchillas, I'm hard pressed to consider Gedankenexperiment as evidence based model. YMMV. I suspect Ms Hossenfelder will have a field day with this one.

It's also symbiotic with urban parking lots. For very little additional cost vs. installing the panels alone, you can install them as a roof over parking lots. Shaded parking is a perk, it's not like a solar parking lot is uglier that a parking lot already is, and there's a colossal amount of big parking lots all over in the US.... something like the whole state of Rhode Island. All of it nearby power grid infrastructure, too. I never understand when people say solar takes up a lot of land. Just use the parking lots.

Combining solar panels with agriculture of various sorts turns out not to be a huge problem. You simply have lower density of solar panels positioned so that they only provide partial shade. The position of the sun relative to the ground moves, so the shadow moves and, even when in shade from direct sunlight, there's ambient light. Not to mention that the panels themselves could be engineered to let some light through. There are also plenty of plants that do just fine in partial or even full shade. So, yes, there is this thing called photosynthesis, and it's not incompatible with solar power generation.

Our solar farms here in PA have plenty of vegetation growing beneath them. They even serve as nesting places for birds on the underside. The idea that everything under them is just dirt with no plants, held by some, is incorrect. They even help a number of animals.

Sorry, but your calculations are off by a lot. There was a shitload more power needed to generate the power the fusion device needed. Qtot is around .01. That's the important number. Qin to Qout looks good on press releases, but ignores the power needed to produce the Qin.

> Commonwealth Fusion Systems have a solution to the problem youâ(TM)re alluding to on their ARC reactor.

They do not.

Forget the reactor for a moment. Let's just talk about getting the energy out of some black box and turning that into electricity. For all realistic* designs, that's a Rankine cycle steam loop. Those cost about 50 cents per watt peak, and the associated transformers and switchyard generally push that up to around $1. In the case of a system where radioactively is present, you need to use a three-loop system with a closed first loop (this is true even if it's not radioactive, but anything "nasty", like sodium metal or what have you). This drives the cost into the $2 to $4 range.

That is four times the cost of a complete PV farm end-to-end, and twice as much as a hybrid design with batteries.

Note that I have not built the reactor yet. And even if it's free, it's still out of the money.

CFS does not have a solution to this problem. No one does.

* There are a number of companies that state they have some non-heat extraction method. They are all full of baloney.

This. So much this. We orgasm over tiny increments, while ignoring the elephant in the room. I've made jokes about needing a fission reactor beside every fusion power source, for tw things. One is to create the tritium the fusion reactor will gullible up, and the other is to provide 10 times the power of the output of the fusion reactor.

All while there is already a well functioning fusion reactor some 93 million miles away. And we're capturing power from it already.

Thanks for correcting me about Bernie Sanders.

Ultimately there's all kinds of people in all so-called generations, which are delineated somewhat arbitrarily (although I think WW2 makes sense as a time separation). Assuming that one's generation determines one's personality is not that far from astrology. It makes a lot more sense to me to explain behaviours, including group behaviours, based on environment and experience.

There is a certain amount of arbitrariness to the assignments of so called generations. Certainly there is some overlap as well, which fuzzes things a bit.

Generalizations follow

As a mid stage boomer, many of us tried something different in raising our children. The business of being our children's best friends, and protecting them from all adversity. That really didn't work out as we thought it would. Many didn't grow to be adults. In the University environment, things got a little strange. When the millennials started coming to college, the cell phone became an electronic umbilical cord. The young folk who never were taught the boundaries they needed, might call mommy or daddy about some professor they didn't like, and mommy or daddy would call wanting the professor fired. Sometimes the parents would come along on job interviews. Cringe level 1000.

We ended up separating the parents from their children for one get together on the orientation weekends. Told them that at 18, their children were now adults, and part of the college experience was for the kids to become adults and make their own decisions and take their own responsibility.

It wasn't super successful, but a few parents paid attention.

And there is something I believe we can lay at the feet of the boomers. The desire to protect their little buddies from all adversity, the refusal to allow the kids any time not supervised by adults, and some social issues I won't go into here, resulted in a non-optimal situation. Physical adults who didn't quite grow up.

That is the big failing of the boomers.

And time marches on.
