> a single line, over a relatively short distance, through terrain that isn't too challenging, going at moderate speeds,

None of this is true, or remarkable.

Almost all high-speed rail lines are a single line.

This line would have been 520 miles, or about 800km. That's longer than almost every high speed rail line in the world. For point of reference, all high speed rail in the UK put together is 1,377km. All high speed rail in Japan is 2,760km. While this single line would not be close to the world's longest (China has a single high speed rail line of nearly 2300km), it's about 30% of the total length of all Japanese high-speed lines put together.

This line was planned to have a max speed of 220mph, which is faster than all but one system in the world.
It's drastic. I'm not taking a position either way because I don't know enough about the tradeoffs. But it's really bad out there, particularly here in SF; maybe worse than you realize.

When mobs of zombies start shuffling out of the Pacific and swarming coastal cities, you call the National Guard and impose martial law, "government overreach" be damned. And when things reach this level of dysfunction in the housing market, it is appropriate to start rationally examining practices we've always taken for granted in the past like unfettered real estate investment.
So they are basically in Real World testing already?

Out of all the battery breakthrough news I read, I think this is the first time any were actually being put into use.
Not just limiting but banning people that don't live in the country more than 70% of the time from living here. We n2eed to ban foreign investment.

Kind of, yes. If you're wrong intentionally, we have all sorts of other words for that, including trolling, propaganda, misdirection, incitement, lying, fraud, perjury, all of which have their own connotations for your intent. We wouldn't really call any of those situations a "mistake".
Nobody cares what people think they want. In 5 years you'll be able to play AAA games on a $500 pc, pay by minute, and it'll be the only way to play them, and people will. Grudgingly, maybe, but they will. Everything on the server ('cloud gaming') is the only air tight DRM method, and publishers will jump on it as soon as it becomes viable at scale.
This. Looking at the route through the SF peninsula, it seemed like every other city wanted a completely different system. Palo Alto wants a trench! Menlo Park wants it elevated! Burlingame wants it at grade! Hell, the damn thing would have had more hills than a rollercoaster.

If your interest is 2% and you believe you can get 4% from some other investment, then some people might ask themselves why 'invest' in paying off your mortgage?
The US Navy is a military organization, they are disciplined and have very clear procedures. Even so, accidents do happen. Also naval scale reactors are safer. Commercial utility size reactors are upscaled versions of naval or laboratory reactors, where you cannot make the same safety guarantees. Take it from Alvin Weinberg:

https://youtu.be/iW8yuyk3Ugw

Also, in the case of an accident, the ship usually goes down and the reactor is naturally cooled and shielded by water. Then the accident us probably classified, because we don't want Russia recovering an US sub, like the CIA did at great taxpayer expense.

I think that SMRs are a way forward, even if it's a temporary solution until other safer, non pressurized reactors are developed. They draw from navy reactors and can be produced in a factory under strict QA, transported on site by truck and installed by qualified staff using clearly documented and reproductible procedures.
The same kind of ethics that can justify every terrible action.

As usual if you feel fine and inline with the company's ethic then go for it.

If your family sits down for dinner and one person gobbles up all the food before anyone else eats, were they within their rights? Will the rest of the family ever invite that person to dinner again?

No. We implement these controls on consumption in all areas of life. "Limit 2" when there's a coupon, for example. "All you can eat" restaurants don't allow take home and sometimes charge you for what you do not actually eat.

We must limit the wealthy's ability to consume all the goods so there are goods left over for people who need to live in them.

How does this not make sense? Why do you think it's better that someone owns 2 houses leaving 1 without a home, than two families owning 2 homes (one each).

Isn't that a better world?
Open source libraries like React should not be attributed to companies. It just so happened that Jordan Walke worked for FB when he wrote the library.

Its not like any of these companies specifically target creation of such tools as part of their business goals.
It also largely answers the question in the first paragraph:

So it's "no, they're just done by default and hidden". Seems like a reasonable thing to do.
> I could never understand why export subsidies are bad for the importing countries

The best explanation I can give is an inversion of the saying "Give a man a fish, and you feed him for a day. Teach him to fish, and you feed him for life."

If you give a man who can feed himself free fish until he loses those skills, he'll become dependent on you and you'll have power over him.

> And while the Chinese are kind enough to help us pay for their products with their own money we can focus instead on other stuff which we’re really great at building/providing as a service.

The Chinese don't seem to be interested in buying any of that (except farm products and raw materials). They're working on domestic substitutes for high-tech things they do by from the US [1]. Maybe the US pursue a "back to the countryside/back to agriculture" movement to adapt to the export subsidies?

Au contraire, the biggest issue that HSR faced was landowners fighting it every step of the way. Between fighting eminent domain and fighting with CEQA (California environmental quality act) it's surprising anything got done.
The early, first generation tube-based computers had tube failures more or less daily. Higher reliability tubes specifically intended for computers were eventually introduced. One trick was to run the tube filaments "derated", or under the rated voltage. The tubes worked fine as logic elements at the lower voltage although that probably messed up their normal response curves. When I saw the Colossus rebuild at Bletchley Park, I asked about tube failure and they confirmed that they run the tubes (or valves, as they call them) on the Colossus at derated voltage, greatly reducing the failure rate.
Digging holes through mountains etc is easy. Getting bureaucrats to approve wildlife impact surveys? Now there’s a challenge.

This narrative is highly suspicious.

Zukerberg openly and repeatedly said that he doesn't care about anyone's privacy for well over a decade[1]. The whole company is built around collecting and selling private information. Why would people who care about privacy interview with Facebook in the first place?

zero-cost abstractions are abstractions where the hand-written code wouldn't be any better than the abstraction.

An example is how Option<Box<T>> optimises down to a single pointer in Rust — the compiler uses its knowledge of how Box<T> is non-nullable, and coopts the null value to represent the None value for the Option.

>Being sentenced to prison had no significant effects on arrests or convictions for violent crimes after release from prison, but imprisonment modestly reduced the probability of violence if comparisons included the effects of incapacitation during imprisonment.

So in the final accounting, probation increases the probability of violence while imprisonment reduces it. Imprisonment reduces violence while the offender is in prison, and it doesn't seem like it increases arrests or convictions afterward.
Yes exactly. Another aspect of this is that as soon as we can actually start completing these projects successfully, their benefits will be incredibly obvious and people will want more. As you said, not even for political reasons or whatever, but just because they're better.

In the long term, streamed games (Stadia or similar) are definitely going to become dominant. Steam, et al, can still be storefronts, if they position themselves as such – we still need content curation.

All one needs is a screen with support (e.g. smartTV, chromecast, steam box), internet, and controllers. Classic game systems might be needed for another 5-10 years. Controllers & form factors matter (e.g. Switch, VR), but the "power" of PCs & game systems are no longer differentiators.
Most of the system follows 150 year old rail right of ways.

Places where it doesn't is through Pacheco Pass and the San Gabriels. Pacheco Pass already has a aqueduct tunnel. Boring a tunnel through that just costs money.

San Gabriels are trickier, really depends engineering vs money vs how fast do you want to go vs surface disruption.
You: Labor organizing is bad.

Also you: a free market alternative to <organized labor> is <organized labor>.

You hate the word union. You seem to have a problem with how unions function in the US. I agree! Having all carpenters represented by a single union isn't necessarily as good an answer as having all carpenters represented by several unions. It creates other problems (unions competing against each other leading to race to the bottom rating, mass firings, etc) but it's really no different than companies just hiring non-union laborers now and would hopefully lead to a larger percentage of labor represented by orgs and not individuals.

There absolutely should be laws in place preventing retaliation and allowing organizations, I just don't think the US model has done well.
The thing is, my observation is true about the broader housing market in the Bay Area. Most homes are not homes owned by individuals with multiple homes. And at worst, they're homes on the rental market, and so still help to meet housing demand. Vacant houses are such a small fraction of the housing stock, that even if all of them were full of resident owners, the price problem would still exist.

Yes, assuming we have a World with infinite resources then your suggestion would be compelling. As we could just manufacture more, and move these people in to other industries, producing ever more stuff for the people higher up the wealth scale.

How do you think that's going to play out with energy production becoming problematic due to climate change, with water becoming hard to come by even in some Western regions, with resources like sand (!) growing in short supply.

Oh, sure, we'll just buy our way out with our endless resources and our ever increasing consumption. WCGW.

The real "half full", ie optimistic, outlook is that we find a way societally to do something like UBI, or spread jobs across more people (3 day week, etc.), or something else, without having to get there through violent revolution or similarly disturbing means.

You're right, I don't know _the_ answer, but I do know it's not greater consumption (ie shift truckers in to a job producing something else), unless we first solve energy production in a massively transformative way.
$3000 monthly is less than 10% of the household income so I don't see how that could ever be considered frivolous.
Thanks for the reply! Isn't enough data about behavior (scrolling speed, typing speed, mouse movements etc) enough to identify an individual, especially when it's combined with something like Browser version? I'd assume those don't change much across sites, i.e. Alice behaves similarly when reading reviews for a new phone or reading the local news.

Height, weight, hair color and year of birth aren't PII, but if you combine them, you're getting pretty close to identifying individuals, it's a behavioral finger print - and though I have no idea if it holds true in general, I'd assume that there's even a strong transfer across devices (a power user scrolls faster on both mobile and desktop).

Is there a way to really solve it? It seems to me that all you actually can do is up the ante, make it harder to do, but with full browser control, it'll be hard to lock them out. And if I'm looking at the behavior of users on my site, I can probably build pretty good replay users that visit the site you're protecting. I remember the "attack" on IRC channels back in the day where you'd join a bunch of bot users that would then have a conversation that is replayed from another channel (possibly in a different language), so timing, interaction etc looked very real (though they may seem a bit rude for not reacting to other people).
Boeing should buy Tesla, they seem to be of the same mind as it pertains to safety.
I honestly don't see the problem here.

It's simple: teachers, nurses, baristas, garbagement, plumbers, etc. won't be able to live there. Nor do they need to.

These people can live somewhere else, far away, and commute in. To entice them to make this ridiculous commute, their pay will have to be extremely high, and they'll probably want shorter hours too (so they can spend half their work-time commuting), so they'll have to hire twice as many people.

So if some wealthy homeowner needs a plumber, it's no problem. Remember, plumbers are usually contractors.
They can call up the plumbing company, who will send a plumber who will drive 2-4 hours to get there, and the same amount to go home. This will result in an enormous charge just for fixing a leaking pipe. But that's OK, because the homeowner is wealthy, remember? They can afford $3k for a service call. If they can't, well maybe they need to rethink where they're living, and sell and move someplace cheaper.

Some jobs just don't even need to be done. Baristas, for instance, aren't really needed. They can be paid a fortune to drive 3 hours each way every day, and this can be reflected in the coffee prices, but will wealthy people pay $30 for a latte? If they do, fine: baristas can commute. If they don't, oh well, the coffee shop can go out of business (or maybe have self-serve lattes), and the wealthy homeowners can go without.

The same goes for teachers. If the wealthy people aren't willing to pay enough taxes for teachers to have $250k salaries to live there, then they don't really need to have teachers, and their kids can go without an education. Maybe they can send their kids to boarding school somewhere cheaper.

Seriously, I think that if people stop fretting about these lower-paid people, and just let the chips fall where they will, the problem will resolve itself one way or another. Either the wealthy people will cave in and get local government to approve more affordable housing construction, or the local real estate market will collapse because people don't really want to live in a place where there's no garbage collection.
Still cheaper than widening I-5, which is the primary alternative.

My theory is that prison is only effective on people that are already fairly morally grounded and with pretty healthy social and mental dynamics. So those folks can and do bounce back.

Can you add more details on how you handle seasons? This is something I've been wondering about. Do you shorten/lengthen your sleep? Or just shift it to always wake up at sunrise? I think shifting seasons might be one "natural" thing which our biology is not "naturally" attuned to, and a fixed-length day would probably be better (maybe we'll have it in the future on a space colony, by I digress).
Fair enough. I'm more familiar with East-West driving than North-South on 93. My perception is that the morning commute into Cambridge/Boston (and the reverse commute) via either the Pike or Route 2 is worse than it was ten years ago. But that may just reflect how relatively built-up Cambridge has become. TBH, the issue is mostly how long it takes to move on surface streets within the city.
I think that a wealth (or capital) tax makes more sense than a land tax.

Why hasn't it happened yet? I can see two reasons. Pick which one you think is more believable.

Reason 1: The rich don't like the idea of a wealth tax, and the rich have a lot of political clout.

Reason 2: The consequences could be rather negative. If the US creates a wealth tax, you'd see an exodus of assets and rich people. It would become a less attractive location for businesses (including startups). Would that be a net win for the US?
