Sure but the advantage of crops is you can easily scale your solar collectors by planting more acres. There are soybean farms with a half million acres out there that would produce significant amounts of biodiesel if used for that purpose. Now algae is a lot more efficient in a physics sense, but an equivalent algae facility would be on the order of 100,000 acres. The water requirements and environmental impacts of open algae pools would be almost unimaginable. Solar powered bioreactors would increase yields and minimize environmental costs, at enormous financial costs, although possibly this would be offset by economies of scale.

Either way a facility that produces economically significant amounts of algae biodiesel would be an engineering megaproject with higher capital and operating costs than crop based biodiesel, but an algae based energy economy is a cool idea for sci fi worldbuilding. In reality where only the most immediately economically profitable technologies survive, I wouldnâ(TM)t count on it being more than a niche application.

It isn't just fanboys. Tesla stock is astronomically overpriced based on the sales performance and outlook of what normal people consider its core business -- electric cars (and government credits). For investors, Tesla is *all* about the stuff that doesn't exist yet, like robotaxis.

Are they wrong to value Musk's promises for Tesla Motors so much? I think so, but it's a matter of opinion. If Tesla actually managed to make the advances in autonomous vehicle technology to make a real robotaxi service viable, I'd applaud that. But I suspect if Musk succeeds in creating a successful robotaxi business, Tesla will move on to focus on something other than that. Tesla for investors isn't about what it is doing now, it's about not missing out on the next big thing.

The real problem with biodiesel would be its impact on agriculture and food prices. Ethanol for fuel has driven global corn prices up, which is good for farmers but bad in places like Mexico where corn is a staple crop. Leaving aside the wildcat homebrewer types who collect restaurant waste to make biodiesel, the most suitable virgin feedstocks for biodiesel on an industrial scale are all food crops.

As for its technical shortcomings, if it even makes any economic sense at all then that's a problem for the chemists and chemical engineers. I suspect biodiesel for its potential environmental benefits wouldn't attract serious investment without some kind of mandate, which would be a really bad thing if you're making it from food crops like oil seeds or soybeans.

I have cars with very basic controls, but even then, one of them has a screen (and a number of basic controls for AC anyway).. I know foe sure that a phone in my hand with the map on it or with a YouTube channel (I listen, I watch the road) is much easier from point of view of reaction speed than the car's touchscreen. A phone I can glance at for a fraction of a second and control it from memory mostly, the car's screen is so much slower, it requires much longer time to deal with its interface Using a touchscreen in a car is more dangerous than a phone, for sure.

Just one point: "free love" actually has a historical definition. It means that sexual activity should not be regulated by governments. That would also, technically, include the right to practice celibacy.

They will have to increase the price eventually as demand for transport overall rises. The point of the pricing is to deter driving enough that the street network operates within its capacity limits; if driving becomes more desirable than status quo ante, they aren't charging enough and will have to raise prices to keep demand manageable.

Think of it this way: either way, traffic will reach some equilibrium. The question is, what is the limiting factor? If using the road is free, then the limiting factor is traffic congestion. If you widen some congested streets, the limiting factor is *still* congestion, so eventually a new equilibrium is found which features traffic jams with even more cars.

The only way to build your way out of this limit, is to add *so* much capacity to the street network that it far outstrips any conceivable demand. This works in a number of US cities, but they're small and have an extensive grid-based street network with few natural barriers like rivers. There is simply no way to retrofit such a street architecture into a city of 8.5 million people where land costs six million dollars an acre.

So imposing use fees is really is the only way to alleviate traffic for a major city like New York or London. This raises economic fairness issues, for sure, but if you want fairness, you can have everyone suffer, or you can provide everyone with better transportation alternatives, but not necessarily the same ones. Yes, the wealthy will be subsidizing the poor, but they themselves will also get rewards well worth the price.

Well, yes -- the lies and the exaggerations are a problem. But even if you *discount* the lies and exaggerations, they're not *all of the problem*.

I have no reason to believe this particular individual is a liar, so I'm inclined to entertain his argument as being offered in good faith. That doesn't mean I necessarily have to buy into it. I'm also allowed to have *degrees* of belief; while the gentleman has *a* point, that doesn't mean there aren't other points to make.

That's where I am on his point. I think he's absolutely right, that LLMs don't have to be a stepping stone to AGI to be useful. Nor do I doubt they *are* useful. But I don't think we fully understand the consequences of embracing them and replacing so many people with them. The dangers of thoughtless AI adoption arise in that very gap between what LLMs do and what a sound step toward AGI ought to do.

LLMs, as I understand them, generate plausible sounding responses to prompts; in fact with the enormous datasets they have been trained on, they sound plausible to a *superhuman* degree. The gap between "accurately reasoned" and "looks really plausible" is a big, serious gap. To be fair, *humans* do this too -- satisfy their bosses with plausible-sounding but not reasoned responses -- but the fact that these systems are better at bullshitting than humans isn't a good thing.

On top of this, the organizations developing these things aren't in the business of making the world a better place -- or if they are in that business, they'd rather not be. They're making a product, and to make that product attractive their models *clearly* strive to give the user an answer that he will find acceptable, which is also dangerous in a system that generates plausible but not-properly-reasoned responses. Most of them rather transparently flatter their users, which sets my teeth on edge, precisely because it is designed to manipulate my faith in responses which aren't necessarily defensible.

In the hands of people increasingly working in isolation from other humans with differing points of view, systems which don't actually reason but are superhumanly believable are extremely dangaerous in my opinion. LLMs may be the most potent agent of confirmation bias ever devised. Now I do think these dangers can be addressed and mitigated to some degree, but the question is, will they be in a race to capture a new and incalculably value market where decision-makers, both vendors and consumers, aren't necessarily focused on the welfare of humanity?

His slogan should be "Everyone's listening!", because it's going to be FBI, CIA, IRS, DHS, DOT, FHA but also the ruzzians and Chinese and Hegseth's wife.

Well, I think it is only possible to make this movie now, after a decade and a half of bullshit that has been pushed onto everyone by various pro trans, pro socialist or even pro Marxist movements.

Now that Trump is running (and likely ruining) the place, it is possible to come out with anything I think and who is going after Brooks, what are they going to do, cancel him? :)))

CPB and the government have been collected data directly from the airlines ever since the aftermath of 9/11 through a number of programs, for example to check passengers against watch lists and to verify the identity of travelers on international flights.

What has changed is that by buying data from a commerical broker instead of a a congressionally instituted program, it bypasses judicial review and limits set by Congress on data collected through those programs -- for example it can track passengers on domestic flights even if they're not on a watch list.

Fascism isn't an ideology; it's more like a disease of ideology. The main characteristic of fascist leaders is that they're unprincipled; they use ideology to control others, they're not bound by it themselves. It's not just that some fascists are left-wing and others are right-wing. Any given fascist leader is left-wing when it suits his purposes and right-wing when that works better for him. The Nazis were socialists until they got their hands on power and into bed with industry leaders, but it wasn't a turn to the right. The wealthy industrialists thought they were using Hitler, but it was the other way around. The same with Mussolini. He was socialist when he was a nobody but turned away from that when he lost his job at a socialist newspaper for advocating militarism and nationalism.

In any case, you should read Umberto Eco's essay on "Ur-Fascism", which tackles the extreme difficulties in characterizing fascism as an ideology (which as I stated I don't think it is). He actually lived under Mussolini.

I think people expect commercial social media networks to be something they can't be -- a kind of commons where you are exposed to the range of views that exist in your community. But that's not what makes social networks money, what makes them money is engagement, and consuming a variety of opinions is tiresome for users and bad for profits. When did you ever see social media trying to engage you with opinions you don't agree with or inform you about the breadth of opinion out there? It has never done that.

The old management of Twitter had a strategy of making it a big tent, comfortable for centrist views and centrist-adjacent views. This enabled it to function as a kind of limited town common for people who either weren't interested in politics, like authors or celebrities promoting their work, or who wanted to reach a large number of mainly apolitical people. This meant drawing lines on both sides of the political spectrum, and naturally people near the line on either side were continually furious with them.

It was an unnatural and unstable situation. As soon as Musk tried to broaden one side of the tent, polarization was inevitable. This means neither X nor Bluesky can be what Twitter was for advertisers and public figures looking for a broad audience.

At present I'm using Mastodon. For users of old Twitter, it must seem like an empty wasteland, but it's a non-commercial network, it has no business imperative to suck up every last free moment of my attention. I follow major news organizations who dutifully post major stories. I follow some interest groups which are active to a modest degree, some local groups who post on local issues, and a few celebrities like George Takei. *Everybody's* not on it, but that's OK; I don't want to spend more than a few minutes a day on the thing so I don't have time to follow everyone I might be interested in. Oh, and moderation is on a per-server basis, so you can choose a server where the admins have a policy you're OK with.

No, there are all kinds of information the government has that are legitimately not available. Sensitive data on private citizens, for example, which is why people are worried about unvetted DOGE employees getting unfettered access to federal systems. Information that would put witnesses in ongoing criminal investigations at risk. Military operations in progress and intelligence assets in use.

The problem is ever since there has been a legal means to keep that information secret, it's also been used to cover up government mistake and misconduct. It's perfectly reasonable for a government to keep things from its citizens *if there is a specific and articulable justification* that can withstand critical examination.

And sometimes those justifications are overridden by public interest concerns -- specifically when officials really want to bury something like the Pentagon Papers because they are embarrassing to the government. "Embarrassing to the government" should be an argument against secrecy, because of the public interest in knowing the government is doing embarrassing things. In the end, the embarrassment caused by the Pentagon Papers was *good* for the country.

All you need to know about RFK's fitness for office is out in public for everyone to see.
