Is there any reason to think that freshly squeezed juice is chemically different from, for example, frozen juice concentrate?

There is reason to think the differences are biotic vs. abiotic, between the two. Our digestive system is dependent on healthy microbiota. Pasteurization would be the difference here.

So it's essentially the same argument as for raw milk, but at least it's less likely to make you sick (?).

Raw milk is on the fringes of the same argument that whole foods play a more beneficial role in healthy gut microbiota and digestion, and that our current models focusing on nutrient composition are incomplete. It says that our measurements are off, and that there’s more to nutrition than composition alone. https://pmc.ncbi.nlm.nih.gov/articles/PMC11901572/

From the Wikipedia page on orange juice:

> Commercial orange juice with a long shelf life is made by pasteurizing the juice and removing the oxygen from it. This removes much of the taste, necessitating the later addition of a flavor pack, generally made from orange products.

https://en.wikipedia.org/wiki/Orange_juice


The same article goes into additional detail:

> Commercial squeezed orange juice is pasteurized and filtered before being evaporated under vacuum and heat. After removal of most of the water, this concentrate, about 65% sugar by weight, is then stored at about 10 °F (−12 °C). Essences, Vitamin C, and oils extracted during the vacuum concentration process may be added back to restore flavor and nutrition.

So essentially there are components that vaporize during processing. The make sure to condense the same components and add them back in so that the orange juice contains all the components of fresh orange juice.


yes it’s been frozen and concentrated..

You can freeze and concentrate a substance without chemically altering it

The difference is that Australia is on earth... where we all live.

In fact, Australia already had people living on it.


Ability to walk up stairs?

I think there are a lot of good futures that involve things being better on Earth


Good futures, sure. But not as cool. No Tannhauser Gate, no Kessel Run.


You know what's cool? Lifting a billion people out of poverty on earth. If you don't think so and still are more motivated by space opera fantasies, there is something wrong with your morals.


Sure, that would be astoundingly amazing.

But the second sentence there is unwarranted. Someone can lament their hopes and dreams dying while still caring about the realistic needs of the world around them.


You don't know me or what motivates me. You're crossing into personal attacks and that's not ok.


are you equally upset that Harry Potter isn’t real?

I don’t mean to come across as rude, I just can’t really understand what you mean unless you’re saying that you’re sad magic isn’t real


If you believed magic was real, wouldn't you be sad to learn it wasn't?

You're saying you never, ever, not once thought interstellar travel and space colonies might happen one day. Far into the future, of course.

My dream of interstellar travel died once I grew up a bit and learned about relativity. But colonies in our solar system and the rest are dead because of money more than anything else.


Yes, only anti-truckers can haul anti-matter since normal CDLs only let you transport ordinary matter. You have to be very careful not to let the anti-trucker go to a ordinary truck stop because things really go down if they run into a ordinary trucker.


There is some good greta joke hidden there but I had enough dovnvotes for today


Why wouldn't it be trained to do that? You can easily include that in the training data.

It's not like the people building Waymo have never heard of flashing your brights before.


Even if it didn't make sense to build new nuclear, that doesn't mean it makes sense to shut of existing nuclear.


Right? Why do we even need all-day trading?

I have seen a once-daily auction proposed, which seems like a sensible approach to me.


That wouldn't be enough liquidity, and also wouldn't solve the problem if the auction happened at a specific time. Day traders would all put in their bid at the last possible moment.

What solves the day trading problem is doing chunked actions at random small intervals (like between 2-7 seconds). Then you can't put your bid in at the last moment because you won't know when it is. So your best bet is to put in your bid when you've chosen a price, knowing that it will resolve within seven seconds or less.


I do see your point regarding timing, but I don't see why daily isn't enough liquidity when, for decades, funds from trades have taken multiple days to clear.

The very existence of holiday weekends shows that it's actually totally fine if you go 72 hours without any trades resolving.


There are whole books on this, but the short summary is that there are infinite times when information can change that would affect the value of a company. Anything less than infinite trading is a compromise where the price is no longer reflective of the value. The bigger the gap in the time, the bigger the gap between price and value.

For example, if you could only trade once a day, let's say a company announces midday that some huge customer has just left their platform. Their price should drop, but without trading it can't. So now everyone knows that their value is lower, but can't do anything about it. So people who own that stock will hold their money and not make other trades, because they know they are going to lose a bunch when trading happens again.

> The very existence of holiday weekends shows that it's actually totally fine if you go 72 hours without any trades resolving.

Trading never stops. There is an entire secondary market that has after hours/weekend trading, and a tertiary private market when that one isn't open. It's just you (and all the other retail traders) who can't trade.

Which if anything proves the opposite of your point. Liquidity is so important that wealthy people set up an entire system to keep trading just so they can still have it.


Is it even wasted if a child gets an education?


All of the children get an education, but you have to divide up the attendance across the available schools.

A single child going to the incorrect school isn’t going to break the system, but when it starts happening at scale it starts diluting the per-student funding in a district, increasing class sizes (reducing the teacher to student ratio) and eventually puts the school over limits and forces nearby children who should be going there into schools that are farther away.


One or two students don't make a difference. But if a number of people lie, then that dilutes the experience of the legit students. So it's not just as simple as you make it sound.

Here's an extreme example. One boy I know went to a school from kindergarten. He was tall and expected to start on the basketball team. Suddenly,in his junior year, several great players showed up from out of nowhere. There were lots of rumors about whether they were legitimately allowed to enroll, but in the end several lifelong students were bumped from the team. The coach was happy. The principal loved the idea. The kids presumably enjoyed the new school. But there were several others who lost an opportunity.

There are downsides to open door policies like you're endorsing. Most of the time, they're not so visible. But when resources are finite, people get hurt.


The correct way to address this is to not have school funding be based on how expensive the nearby houses are.


Can’t speak for Chicago, but in my city the schools get similar funds on a per-student basis yet still have very large differences in academics from school to school.

The reason parents try to get into different schools isn’t to chase funding, it’s to get into the one with the best outcomes. A lot of that comes from parental involvement and having a critical mass of engaged students and parents, not the dollar amount spent on each student.


"A lot of that comes from parental involvement and having a critical mass of engaged students and parents, not the dollar amount spent on each student."

FYI, parent engagement is also heavily proportional to parent income/property prices.

Very hard to be engaged at school with double/triple working class jobs.


In Chicago subrubs school funding is largely based on local property taxes. Expensive neighborhoods have better funded schools. Of course there's also federal funding for poor schools so really the worst funded schools are the ones where everyone is lower middle class but the best funded schools are in the richest districts. Of course as you point out parental involvement is more important than funding, but they tend to be correlated and funding still matters.


I'm glad that's how it works where you live. In Illinois, most school funding comes directly from property taxes, meaning rich areas get more.

For state funding, they use a system called EBF which is better than straightforwardly giving out money based on local property taxes. However, it is far from fair. As an example, part of the calculation is what's called a "regionalization factor" - where funding is reduced for areas with lower local average incomes.


Then "school district fraud" shouldn't be a problem. If a parent is willing to committing a crime to get their kid into a good school, they're heavily engaged and involved.


Schools have limited capacity. If they fill up with students from far away, nearby students who have a real right to be there get pushed out.

This isn’t a topic where you can think in terms of a single child only.


School bodies expand and contract over time as the demographic makeup of a district and school changes. "Limited capacity" isn't strictly true.


School sizes do change over long time horizons as demographics grow. This is true.

But school buildings have limited capacity and teacher:student ratios should be maintained. These cannot be changed instantly. Planning happens according to people actually living there, so if a lot of people are circumventing the rules and cheating their way in it breaks the system.


> School sizes do change over long time horizons

Not even very long horizons. For example, a hot housing market can cause a rush of young families into a district as older retirees cash out and move to Florida or whatever. Schools adapt to this.

I agree following rules is important. What kind of example are you setting for your kids, right? But having some perspective is also important.


How do you propose schools be funded?


Not OP, but IMO pretty much any funding mechanism other than local property taxes funding the local school is better.


How about only taxing households with school-age residents?


Will work out great for you for a the first two decades.


Yeah, that's the opposite direction I was thinking. Everyone benefits from having an educated next generation.


Federally. Every child deserves the same educational opportunity.


Bingo.
